					<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>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>

									<p>フラクトグラフィーは、破壊された表面の特徴を研究するもので、歴史的には顕微鏡または SEM を使用して調査されてきました。フィーチャのサイズに応じて、表面分析には顕微鏡 (マクロ フィーチャ) または SEM (ナノおよびマイクロ フィーチャ) が選択されます。どちらも最終的には破壊メカニズムのタイプを特定できるようになります。顕微鏡には効果的ではありますが、明らかな限界があり、SEM は原子レベルの分析を除いて、ほとんどの場合、破面測定には非実用的であり、広範な使用能力がありません。光学計測技術の進歩により、NANOVEA <a href="https://nanovea.com/profilometers/">3D非接触形状計</a> ナノスケールからマクロスケールまでの 2D および 3D 表面測定を提供する機能を備え、現在、最適な機器とみなされています</p>								</div>

									<p>SEMとは異なり、3D非接触プロフィロメータは、SEMよりも優れた垂直・水平方向の寸法を提供しながら、ほぼすべての表面、サンプルサイズ、最小限のサンプル前処理で測定することができます。プロファイラでは、ナノからマクロレンジの形状を一度の測定で捉えることができ、試料の反射率の影響を受けることはありません。透明、不透明、鏡面、拡散、研磨、粗面など、あらゆる材質を簡単に測定することができます。3D非接触プロフィロメータは、SEMの数分の一のコストで、表面破壊研究を最大化するための広範でユーザーフレンドリーな機能を提供します。</p>								</div>

					<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>

					<description><![CDATA[<p>POLYMER BELTS WEAR AND FRICTION USING a TRIBOMETER Prepared by DUANJIE LI, PhD INTRODUCTION Belt drive transmits power and tracks relative movement between two or more rotating shafts. As a simple and inexpensive solution with minimal maintenance, belt drives are widely used in a variety of applications, such as bucksaws, sawmills, threshers, silo blowers and conveyors. Belt drives can protect the machinery from overload as well as damp and isolate vibration. IMPORTANCE OF WEAR EVALUATION FOR BELT DRIVES Friction and wear are inevitable for the belts in a belt-driven machine. Sufficient friction ensures effective power transmission without slipping, but excessive friction may rapidly wear the belt. Different types of wear [&#8230;]</p>

									<p>ベルト駆動の機械ではベルトの摩擦と摩耗が避けられません。十分な摩擦があればスリップすることなく効果的に動力を伝達できますが、過度の摩擦はベルトを急速に摩耗させる可能性があります。ベルトドライブの運転中は、疲労、摩耗、摩擦などさまざまな種類の摩耗が発生します。ベルトの寿命を延ばし、ベルトの修理や交換にかかる費用と時間を削減するためには、ベルトの摩耗性能を確実に評価することがベルトの寿命、生産効率、アプリケーションの性能を向上させるために重要です。ベルトの摩擦係数や摩耗量を正確に測定することで、ベルトの研究開発や品質管理が容易になります。</p>								</div>

									<p>本研究では、ベルトの摩擦係数と摩耗量を良好に制御し定量的に評価するナノビア T2000トライボメーターの能力を紹介しました。ベルトの摩擦と耐摩耗性には、表面のテクスチャが重要な役割を担っています。テクスチャを施したベルトは摩擦係数が0.5程度と安定しており寿命も長いため、工具の修理や交換にかかる時間やコストを削減することができます。一方、平滑ベルトは鋼球との過度な摩擦によりベルトが急速に摩耗します。更にベルトにかかる負荷は寿命の重要な要素になります。過負荷は非常に高い摩擦を引き起こし、ベルトの摩耗を加速させます。</p>
<p>NANOVEA T2000トライボメータは、ISOおよびASTMに準拠した回転モードとリニアモードによる精密で再現性の高い摩耗・摩擦試験と、オプションで高温摩耗、潤滑、摩擦腐食モジュールを1つのシステムに統合して使用することが可能です。&nbsp;<span style="font-size: 16.8px;">NANOVEAの&nbsp;</span>本装置は薄膜や厚膜、軟質や硬質のコーティング、フィルム、基材などのトライボロジー特性をフルレンジで測定できる理想的な装置です。</p>								</div>

					<description><![CDATA[<p>FOSSIL MICROSTRUCTURE USING 3D PROFILOMETRY Prepared by DUANJIE LI, PhD INTRODUCTION Fossils are the preserved remains of traces of plants, animals and other organisms buried in sediment under ancient seas, lakes and rivers. The soft body tissue usually decays after death, but the hard shells, bones and teeth fossilize. Microstructure surface features are often preserved when mineral replacement of the original shells and bones takes place, which provides an insight into the evolution of weather and the formation mechanism of fossils. IMPORTANCE OF A 3D NON-CONTACT PROFILOMETER FOR FOSSIL EXAMINATION 3D profiles of the fossil enable us to observe the detailed surface features of the fossil sample from a closer [&#8230;]</p>

					<description><![CDATA[<p>PROCESSED LEATHER SURFACE FINISH USING 3D PROFILOMETRY Prepared by CRAIG LEISING INTRODUCTION Once the tanning process of a leather hide is complete the leather surface can undergo several finishing processes for a variety of looks and touch. These mechanical processes can include stretching, buffing, sanding, embossing, coating etc. Dependent upon the end use of the leather some may require a more precise, controlled and repeatable processing. IMPORTANCE OF PROFILOMETRY INSPECTION FOR R&#38;D AND QUALITY CONTROL Due to the large variation and unreliability of visual inspection methods, tools that are capable of accurately quantifying micro and nano scales features can improve leather finishing processes. Understanding the surface finish of leather in [&#8230;]</p>

					<description><![CDATA[<p>ORGANIC SURFACE TOPOGRAPHY USING PORTABLE 3D PROFILOMETER Prepared by CRAIG LEISING INTRODUCTION Nature has become a vital pool of inspiration for the development of improved surface structure. Understanding the surface structures found in nature has led to adhesion studies based on gecko’s feet, resistance studies based on a sea cucumbers textural change and repellency studies based from leaves, among many others. These surfaces have a number of potential applications from biomedical to clothing and automotive. For any of these surface breakthroughs to be successful, fabrication techniques must be developed so surface characteristics can be mimicked and reproduced. It is this process that will require identification and control. IMPORTANCE OF PORTABLE [&#8230;]</p>

									<p style="text-align: justify;">Chromatic Light テクノロジーを活用した NANOVEA Jr25 ポータブル <a href="https://nanovea.com/profilometers/">光学プロファイラー</a> ほぼあらゆる材料を測定できる優れた能力を備えています。これには、自然界の幅広い表面特性に見られる、独特で急な角度、反射面と吸収面が含まれます。 3D 非接触測定により、完全な 3D 画像が提供され、表面の特徴をより完全に理解できるようになります。 3D 機能がなければ、自然の表面の識別は 2D 情報または顕微鏡画像のみに依存することになり、調査対象の表面を適切に模倣するのに十分な情報が得られません。製造を成功させるには、特にテクスチャー、形状、寸法などの表面特性の全範囲を理解することが重要です。</p>
