					<description><![CDATA[<p>SHOT PEENED SURFACE ANALYSIS USING 3D NON-CONTACT PROFILOMETER Prepared by CRAIG LEISING INTRODUCTION Shot peening is a process in which a substrate is bombarded with spherical metal, glass, or ceramic beads—commonly referred to as &#8220;shot&#8221;—at a force intended to induce plasticity on the surface. Analyzing the characteristics before and after peening provides crucial insights for enhancing process comprehension and control. The surface roughness and coverage area of dimples left by the shot are especially noteworthy aspects of interest. Importance of 3D Non-Contact Profilometer for Shot-Peened Surface Analysis Unlike traditional contact profilometers, which have traditionally been used for shot-peened surface analysis, 3D non-contact measurement provides a complete 3D image to offer [&#8230;]</p>

					<description><![CDATA[<p>PAINT SURFACE MORPHOLOGY AUTOMATED REAL-TIME EVOLUTION MONITORINGUSING NANOVEA 3D PROFILOMETER Prepared by DUANJIE LI, PhD INTRODUCTION Protective and decorative properties of paint play a significant role in a variety of industries, including automotive, marine, military, and construction. To achieve desired properties, such as corrosion resistance, UV protection, and abrasion resistance, paint formulas and architectures are carefully analyzed, modified, and optimized. IMPORTANCE OF 3D NON-CONTACT PROFILOMETER FOR DRYING PAINT SURFACE MORPHOLOGY ANALYSIS Paint is usually applied in liquid form and undergoes a drying process, which involves the evaporation of solvents and the transformation of the liquid paint into a solid film. During the drying process, the paint surface progressively changes its [&#8230;]</p>

<p>このアプリケーションでは、NANOVEA ST500 3D非接触型プロフィロメーターの能力を、乾燥過程における塗料表面の形態変化をモニターすることで紹介しました。サンプル表面を同時にスキャンする192個の光スポットからなるラインを生成する高速光学ラインセンサーにより、比類のない精度を確保しながら、時間効率の高い研究が可能になりました。</p>
<p>取得ソフトウェアのマクロ機能は、その場で3D表面形状の自動測定をプログラミングすることを可能にし、特定の目標時間間隔で複数のスキャンを含む長期測定に特に有用である。これにより、時間、労力、ユーザーエラーの可能性が大幅に削減される。表面形状の漸進的な変化は、塗料が乾燥するにつれてリアルタイムで連続的にモニター・記録されるため、塗料の乾燥メカニズムに関する貴重な知見が得られます。</p>
<p>ここに示したデータは、解析ソフトウェアで利用可能な計算のほんの一部です。NANOVEAプロフィロメーターは、透明、暗色、反射性、不透明を問わず、事実上あらゆる表面を測定することができます。</p></div></div></div>

					<description><![CDATA[<p>Flooring Wear Testing Progressive Wear Mapping of Flooring​ using Tribometer with integrated Profilometer Prepared by FRANK LIU INTRODUCTION Flooring materials are designed to be durable, but they often suﬀer wear and tear from everyday activities such as movement and furniture use. To ensure their longevity, most types of ﬂooring have a protective wear layer that resists damage. However, the thickness and durability of the wear layer vary depending on the ﬂooring type and level of foot traﬃc. In addition, diﬀerent layers within the ﬂooring structure, such as UV coatings, decorative layers, and glaze, have varying wear rates. That&#8217;s where progressive wear mapping comes in. Using the NANOVEA T2000 Tribometer with [&#8230;]</p>

									<p>床材は耐久性があるように設計されていますが、移動や家具の使用などの日常活動によって磨耗することがよくあります。耐久性を確保するために、ほとんどの種類のフローリングには損傷を防ぐ保護摩耗層が付いています。ただし、摩耗層の厚さと耐久性は、床材の種類や歩行量によって異なります。さらに、UV コーティング、装飾層、釉薬など、フローリング構造内のさまざまな層の摩耗率は異なります。そこで、プログレッシブ ウェア マッピングが登場します。統合された NANOVEA T2000 トライボメーターを使用する <a style="background-color: #ffffff;" href="https://nanovea.com/profilometers/">3D非接触形状測定装置</a>床材の性能と寿命を正確に監視、分析することができます。さまざまな床材の摩耗挙動に関する詳細な洞察を提供することで、科学者や技術専門家は、新しい床材システムを選択および設計する際に、より多くの情報に基づいた意思決定を行うことができます。</p>								</div>

									<p>床材の試験では、従来、摩耗に対する耐久性を判断するために、サンプルの摩耗率を中心にしてきました。しかし、プログレッシブ摩耗マッピングでは、試験中のサンプルの摩耗率を分析し、その摩耗挙動に関する貴重な知見を得ることができます。この詳細な分析により、摩擦データと摩耗率の相関関係が明らかになり、摩耗の根本原因を特定することができます。摩耗試験において、摩耗量は一定ではないことに留意する必要があります。そのため、摩耗の進行を観察することで、試料の摩耗をより正確に評価することができます。従来の試験方法を超えて、プログレッシブ摩耗マッピングの採用は、床材試験の分野で大きな進歩に寄与しています。</p>								</div>

					<description><![CDATA[<p>ROUGHNESS MAPPING INSPECTION USING 3D PROFILOMETRY Prepared by DUANJIE, PhD INTRODUCTION Surface roughness and texture are critical factors that impact the final quality and performance of a product. A thorough understanding of surface roughness, texture, and consistency is essential for selecting the best processing and control measures. Fast, quantifiable, and reliable inline inspection of product surfaces is in need to identify the defective products in time and optimize production line conditions. IMPORTANCE OF 3D NON-CONTACT PROFILOMETER FOR IN-LINE SURFACE INSPECTION Surface defects in products result from materials processing and product manufacturing.

					<description><![CDATA[<p>WELd surface inspection using a portable 3d profilometer Prepared by CRAIG LEISING INTRODUCTION It may become critical for a particular weld, typically done by visual inspection, to be investigated with an extreme level of precision. Specific areas of interest for precise analysis include surface cracks, porosity and unfilled craters, regardless of subsequent inspection procedures. Weld characteristics such as dimension/shape, volume, roughness, size etc. can all be measured for critical evaluation. IMPORTANCE OF 3D NON-CONTACT PROFILOMETER FOR WELD SURFACE INSPECTION Unlike other techniques such as touch probes or interferometry, the NANOVEA 3D Non-Contact Profilometer, using axial chromatism, can measure nearly any surface, sample sizes can vary widely due to open staging [&#8230;]</p>

					<description><![CDATA[<p>INDUSTRIAL COATING SCRATCH AND WEAR EVALUATION USING A TRIBOMETER Prepared by DUANJIE LI, PhD &#38; ANDREA HERRMANN INTRODUCTION Acrylic urethane paint is a type of fast-dry protective coating widely used in a variety of industrial applications, such as floor paint, auto paint, and others. When used as floor paint, it can serve areas with heavy foot and rubber-wheel traffic, such as walkways, curbs and parking lots. IMPORTANCE OF SCRATCH AND WEAR TESTING FOR QUALITY CONTROL Traditionally, Taber abrasion tests were carried out to evaluate the wear resistance of acrylic urethane floor paint according to the ASTM D4060 standard. However, as mentioned in the standard, “For some materials, abrasion tests utilizing [&#8230;]</p>

									<p>従来、アクリルウレタン床用塗料の耐摩耗性評価には、ASTM D4060規格に準拠したテーバー摩耗試験が行われてきた。しかし、規格にあるように「材料によっては、試験中にホイールの研磨特性が変化するため、テーバー摩耗試験でばらつきが生じることがある」1ため、試験結果の再現性が低く、異なる試験所からの報告値を比較することが困難な場合があります。また、Taber摩耗試験では、耐摩耗性は指定された摩耗回数における重量減少として計算される。しかし、アクリルウレタン系床用塗料の推奨乾燥膜厚は37.5～50μm2である。</p><p>テーバーアブレーザーによる激しい摩耗は、アクリルウレタン塗膜を素早く摩耗させ、基材に質量損失を生じさせ、塗膜の重量減少の計算に大きな誤差を生じさせます。また、摩耗試験中に塗料に研磨粒子が混入することも、誤差の原因となります。したがって、塗膜の摩耗評価を再現性よく行うためには、十分に制御された定量的で信頼性の高い測定が重要です。さらに、その <a href="https://nanovea.com/scratch-tester/">スクラッチテスト</a> は、実際のアプリケーションで早期の接着剤/粘着剤の不具合を検出することができます。</p>								</div>

									<p style="text-align: justify;">各試料について，異なる回転数（100，150，300，800サイクル）で4回のピンオンディスク摩耗試験を実施し，摩耗の進行を観察した。摩耗試験を行う前に，NANOVEA 3D非接触プロファイラで試料の表面形状を測定し，表面粗さを定量化した．図1に示すように、すべてのサンプルの表面粗さは約1μmと同等であった。COFは、図2に示すように、摩耗試験中にその場で記録されました。図4は、100、150、300、および800サイクル後の摩耗痕の変化を示し、図3は、摩耗プロセスの異なる段階での異なる試料の平均摩耗速度をまとめたものである。</p><p> </p><p style="text-align: justify;">他の 3 つのサンプルの COF 値が ~0.07 であるのに対して、サンプル A は初期に ~0.15 という非常に高い COF を示し、徐々に増加し 300 回の摩耗サイクルの後に ~0.3 で安定しました。このような高いCOFは摩耗プロセスを加速し、図4に示すように相当量の塗料カスを発生させます。サンプルAのトップコートは、最初の100回転で除去され始めています。図 3 に示すように、サンプル A は最初の 300 サイクルで ~5 μm2/N という最高の摩耗率を示し、金属基材の耐摩耗性が向上したため ~3.5 μm2/N にわずかに減少しています。サンプルCのトップコートは、図4に示すように、150摩耗サイクルの後に破損し始め、これは図2のCOFの増加によっても示されています。</p><p> </p><p style="text-align: justify;">これに対し、試料Bと試料Dは、トライボロジー特性が向上しています。試料Bは試験中ずっと低いCOFを維持しており、COFは~0.05から~0.1へとわずかに増加しています。このような潤滑効果は耐摩耗性を大幅に向上させ、800回の摩耗サイクルの後でもトップコートは下地のプライマーに対して優れた保護効果を発揮しています。サンプルBでは、800回の摩耗サイクルで、最小の平均摩耗量である〜0.77μm2/Nが測定されています。サンプルDのトップコートは、図2のCOFの急激な増加によって反映されているように、375サイクル後に剥離し始めます。サンプルDの平均摩耗量は、800サイクルで約1.1μm2/Nです。</p><p> </p><p style="text-align: justify;">ナノビアトライボメータは、従来のテーバー摩耗測定と比較して、再現性のある評価と市販の床・自動車塗料の品質管理を保証する、定量的で信頼性の高い摩耗評価を提供します。さらに、COFのその場測定が可能なため、摩耗プロセスのさまざまな段階とCOFの変化を関連付けることができ、さまざまな塗膜の摩耗メカニズムや摩擦特性に関する基礎的な理解を深める上で重要な役割を果たします。</p>								</div>

					<description><![CDATA[<p>FRACTOGRAPHY ANALYSIS USING 3D PROFILOMETRY Prepared by CRAIG LEISING INTRODUCTION Fractography is the study of features on fractured surfaces and has historically been investigated via Microscope or SEM. Depending on the size of the feature, a microscope (macro features) or SEM (nano and micro features) are selected for the surface analysis. Both ultimately allowing for the identification of the fracture mechanism type. Although effective, the Microscope has clear limitations and the SEM in most cases, other than atomic-level analysis, is unpractical for fracture surface measurement and lacks broader use capability. With advances in optical measurement technology, the NANOVEA 3D Non-Contact Profilometer is now considered the instrument of choice, with its [&#8230;]</p>

					<description><![CDATA[<p>FIBERGLASS SURFACE TOPOGRAPHY USING 3D PROFILOMETRY Prepared by CRAIG LEISING INTRODUCTION Fiberglass is a material made from extremely fine fibers of glass. It is used as a reinforcing agent for many polymer products; the resulting composite material, properly known as fiber-reinforced polymer (FRP) or glass-reinforced plastic (GRP), is called &#8220;fiberglass&#8221; in popular usage. IMPORTANCE OF SURFACE METROLOGY INSPECTION FOR QUALITY CONTROL Although there are many uses for Fiberglass reinforcement, in most applications it is crucial that they are as strong as possible. Fiberglass composites have one of the highest strength to weight ratios available and in some cases, pound for pound it is stronger than steel. Aside from high strength, [&#8230;]</p>

									ガラス繊維強化材には多くの用途がありますが、ほとんどの用途において可能な限り強度を高めることが極めて重要です。ガラス繊維複合材料は、重量に対する強度が最も高い材料の一つであり、場合によっては鋼鉄よりも高い強度を持つこともあります。高い強度の他に、露出した表面積をできるだけ小さくすることも重要です。グラスファイバーの表面積が大きいとケミカル・アタックや材料の膨張に対して構造体がより脆弱になる可能性があります。そのため、表面検査は品質管理生産において非常に重要です。								</div>
