									<p data-start="836" data-end="1458">The ability to accurately characterize tooth surfaces, including micro-roughness and 3D surface topography at the nanometer scale, enables advanced research and applications in orthodontics and dental materials science. Non-contact optical profilometry provides a precise method for measuring dental surface roughness and analyzing tooth surface morphology without damaging delicate structures. These measurements support the development of composite dental materials that replicate the natural surface roughness of enamel, as well as the design and fabrication of patient-specific dental casts and restorative components.</p><p data-start="1460" data-end="1982">Low surface roughness plays a primary role in limiting bacterial adhesion and plaque formation, thereby reducing the risk of cavities. An increase in average roughness (Ra) above 2 µm leads to a steep increase in biofilm formation in vivo.¹ An Ra of 0.2 µm is considered the threshold value below which no further reduction in bacterial adhesion can be expected.²</p><p data-start="1984" data-end="2182">Reconstruction of the tooth’s 3D surface topography enables the fabrication of dental casts, which are essential for accurate diagnosis, treatment planning, and the fabrication of dental appliances.</p>								</div>

Chromatic Light technology offers significant advantages over classical touch probe techniques. It acquires data points from deep crevices and complex geometries without introducing measurement errors or artifacts caused by local plastic deformation and without requiring extensive data manipulation.</p><p data-start="715" data-end="1135">Compared to focus variation systems, single-point optical sensing provides superior lateral and height accuracy, with X/Y resolution below 0.5 µm, maximum vertical resolution of 1.9 nm, and the ability to measure surface angles up to 87°.

					<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 [&#8230;]</p>

									<p>图 2、图 3 和图 4 分别显示了代表性时间的假色视图、三维视图和干燥油漆形貌的二维剖面图。图像中的假色有助于检测不易辨认的特征。不同的颜色代表样品表面不同区域的高度变化。三维视图为用户提供了从不同角度观察油漆表面的理想工具。在测试的前 30 分钟，油漆表面的假色逐渐从暖色调变为冷色调，表明在此期间高度随时间逐渐降低。这一过程会减慢，正如在 30 分钟和 60 分钟时比较油漆的颜色变化轻微所显示的那样。</p><p>样品的平均高度和粗糙度 Sa 值与涂料干燥时间的函数关系如图 5 所示。 表 1 列出了干燥 0、30 和 60 分钟后涂料的完整粗糙度分析。可以看出，在干燥时间的前 30 分钟内，油漆表面的平均高度从 471 微米迅速下降到 329 微米。溶剂汽化的同时，表面纹理也随之形成，导致粗糙度 Sa 值从 7.19 微米增加到 22.6 微米。此后，涂料干燥过程减慢，导致样品高度和 Sa 值逐渐下降，在 60 分钟时分别降至 317 微米和 19.6 微米。</p><p>这项研究强调了 NANOVEA 3D 非接触式轮廓仪在实时监测干燥涂料的 3D 表面变化方面的能力，为了解涂料干燥过程提供了宝贵的资料。通过在不接触样品的情况下测量表面形态，轮廓仪避免了滑动测针等接触式技术可能对未干涂料造成的形状改变。这种非接触式方法可确保对干燥涂料表面形态进行准确可靠的分析。</p>								</div>

<p>在这一应用中，我们展示了 NANOVEA ST500 3D 非接触式轮廓仪在监测干燥过程中涂料表面形态演变方面的能力。高速光学线传感器可产生一条由 192 个光点组成的线，同时扫描样品表面，从而在确保无与伦比的精确度的同时提高了研究的时间效率。</p>
<p>采集软件的宏功能可对三维表面形态进行编程自动测量，特别适用于在特定目标时间间隔内进行多次扫描的长期测量。它大大减少了时间、精力和用户出错的可能性。在涂料干燥的过程中，表面形态的渐进变化会被持续监测和实时记录，为了解涂料的干燥机理提供有价值的信息。</p>
<p>此处显示的数据仅代表分析软件中可用计算的一小部分。NANOVEA 轮廓仪几乎能够测量任何表面，无论是透明表面、暗表面、反射表面还是不透明表面。</p></div></div></div>

									<p>传统上，根据ASTM D4060标准，采用Taber磨损试验来评估丙烯酸聚氨酯地坪漆的耐磨性。然而，正如标准中所提到的，"对于某些材料，由于测试过程中车轮的磨料特性发生变化，使用Taber磨料磨具进行的磨损测试可能会发生变化。“1这可能导致检测结果的可重复性差，并造成比较不同实验室报告的值的困难。此外，在Taber磨损试验中，耐磨性计算为在指定次数的磨损循环下的重量损失。而丙烯酸聚氨酯地坪漆的推荐干膜厚度为37.5 ~ 50 μm2。</p><p>Taber Abraser的侵蚀性磨蚀过程可以迅速磨穿丙烯酸聚氨酯涂层，并造成基材的质量损失，从而导致涂料重量损失计算的巨大误差。在磨蚀试验过程中，磨料颗粒植入涂料中也会造成误差。因此，一个控制良好的可量化和可靠的测量对于确保涂料的可重复性磨损评估至关重要。此外，还有 <a href="https://nanovea.com/scratch-tester/">划痕测试</a> 允许用户在实际应用中检测到过早的粘合剂/胶粘剂失效。</p>								</div>

									<p style="text-align: left;">NANOVEA 摩擦计用于评估摩擦学行为，例如摩擦系数、COF 和耐磨性。将 SS440 球头（直径 6 毫米，等级 100）应用于测试涂料。 COF 是现场记录的。磨损率K的计算公式为K=V/(F×s)=A/(F×n)，其中V为磨损体积，F为法向载荷，s为滑动距离，A为磨损轨迹的横截面积，n是转数。表面粗糙度和磨损轨迹轮廓由 NANOVEA 评估 <a href="https://nanovea.com/profilometers/">光学轮廓仪</a>，并使用光学显微镜检查磨损轨迹形态。</p>								</div>

									<p style="text-align: justify;">在不同转数(100、150、300和800循环)下，对每个样品进行了四次针对盘磨损试验，以监测磨损的演变。在进行磨损测试之前，用NANOVEA 3D非接触剖面仪测量样品的表面形貌，以量化表面粗糙度。所有样品的表面粗糙度均约为1 μm，如图1所示。COF在磨损试验中原地记录，如图2所示。图4为100、150、300和800循环后的磨损轨迹演变，图3为不同样品在磨损过程不同阶段的平均磨损率。</p><p> </p><p style="text-align: justify;">与其他三种样品的COF值~0.07相比，样品a的COF值在开始时要高得多，为~0.15，经过300次磨损循环后，COF值逐渐增加，稳定在~0.3。如此高的COF加速了磨损过程，并产生了大量的油漆碎片，如图4所示——样品a的面漆在前100转中已经开始被去除。如图3所示，样品A在前300个循环中磨损率最高，为~5 μm2/N，由于金属基体的耐磨性较好，磨损率略微下降到~3.5 μm2/N。样品C的面漆在150次磨损后开始失效，如图4所示，图2中COF的增加也说明了这一点。</p><p> </p><p style="text-align: justify;">相比之下，样品B和样品D表现出增强的摩擦学性能。样品B在整个测试过程中保持较低的COF - COF从~0.05轻微增加到~0.1。这样的润滑效果大大提高了它的耐磨性-面漆在800次磨损循环后仍然对底漆提供优越的保护。样品B在800次循环时的最低平均磨损率仅为~0.77 μm2/N。样品D的面漆在375次循环后开始分层，从图2中COF的突然增加可以看出。样品D在800次循环时的平均磨损率约为1.1 μm2/N。</p><p> </p><p style="text-align: justify;">与传统的Taber磨损测量相比，NANOVEA摩擦仪提供了良好控制的可量化和可靠的磨损评估，确保了商业地板/汽车涂料的可重复性评估和质量控制。此外，原位COF测量的能力使用户能够将磨损过程的不同阶段与COF的演变联系起来，这对于提高对各种油漆涂层的磨损机制和摩擦学特性的基本认识至关重要。</p>								</div>

									<p>断口分析是对断裂表面特征的研究，历史上一直通过显微镜或 SEM 进行研究。根据特征的大小，选择显微镜（宏观特征）或SEM（纳米和微观特征）进行表面分析。两者最终都可以识别断裂机制类型。尽管有效，但显微镜具有明显的局限性，并且在大多数情况下，除了原子级分析之外，SEM 对于断裂表面测量来说是不切实际的，并且缺乏更广泛的使用能力。随着光学测量技术的进步，NANOVEA <a href="https://nanovea.com/profilometers/">3D 非接触式轮廓仪</a> 现在被认为是首选仪器，能够通过宏观尺度 2D 和 3D 表面测量提供纳米级测量</p>								</div>

									<p>与SEM不同，3D非接触式轮廓仪几乎可以测量任何表面和样品尺寸，只需最少的样品准备，同时提供优于SEM的垂直/水平尺寸。使用轮廓仪，从纳米到宏观范围的特征都可以在一次测量中捕捉到，而样品反射率的影响为零。可以轻松地测量任何材料：透明的、不透明的、镜面的、扩散的、抛光的、粗糙的等等。三维非接触式轮廓仪提供了广泛和用户友好的能力，以SEM的一小部分成本，最大限度地提高表面断裂研究。</p>								</div>

									<p>在这个应用中，我们展示了NANOVEA ST400 3D非接触式轮廓仪是如何精确表征断裂表面的全部地形（纳米、微观和宏观特征）的。从三维区域中，可以清楚地识别出表面，并且可以快速提取子区域或剖面/横截面，并通过无尽的表面计算列表进行分析。亚纳米级的表面特征可以通过集成的AFM模块进一步分析。</p><p>此外，NANOVEA还在其Profilometer阵容中加入了一个便携式版本，这对于不可移动的裂缝表面现场研究来说尤其重要。有了这些广泛的表面测量能力，使用一台仪器进行断裂表面分析从未如此简单和方便。</p>								</div>

									<p>摩擦和磨损对于皮带驱动的机器中的皮带来说是不可避免的。足够的摩擦确保有效的动力传输而不打滑，但过度的摩擦可能会迅速磨损皮带。不同类型的磨损，如疲劳、磨损和摩擦，都发生在皮带传动操作中。为了延长皮带的使用寿命，减少皮带维修和更换的成本和时间，可靠地评估皮带的磨损性能对于提高皮带寿命、生产效率和应用性能是可取的。准确测量皮带的摩擦系数和磨损率，有利于研发和皮带生产的质量控制。</p>								</div>

									<p>在这项研究中，我们展示了NANOVEA T2000摩擦仪在以良好的控制和定量方式评估皮带的摩擦系数和磨损率方面的能力。在皮带的使用性能中，表面纹理对皮带的摩擦和耐磨性起着关键作用。有纹理的皮带表现出稳定的摩擦系数约为0.5，并拥有较长的使用寿命，从而减少了工具维修或更换的时间和成本。相比之下，光滑皮带对钢球的过度摩擦会迅速磨损皮带。此外，皮带上的负载是影响其使用寿命的一个重要因素。过载会产生非常大的摩擦，导致皮带加速磨损。</p>
<p>NANOVEA T2000摩擦仪采用符合ISO和ASTM标准的旋转和线性模式，提供精确和可重复的磨损和摩擦测试，并在一个预集成的系统中提供可选的高温磨损、润滑和摩擦腐蚀模块。&nbsp;<span style="font-size: 16.8px;">NANOVEA的&nbsp;</span>无与伦比的产品系列是确定薄或厚、软或硬的涂层、薄膜和基材的全部摩擦学特性的理想解决方案。</p>								</div>

									<p>化石是埋在古代海洋、湖泊和河流下的沉积物中的植物、动物和其他生物的痕迹的保存遗迹。软体组织通常在死后腐烂，但硬壳、骨骼和牙齿会成为化石。原有的贝壳和骨骼发生矿物替换时，微观结构的表面特征往往被保留下来，这为了解天气的演变和化石的形成机制提供了启示。</p>								</div>

									<p><span style="font-size: 16.8px;">在这个应用中，我们使用NANOVEA Jr25便携式非接触式轮廓仪全面研究了腕足类和腕足类茎化石的三维表面特征。我们展示了该仪器可以精确描述化石样品的三维形态。然后进一步分析了样品有趣的表面特征和纹理。腕足类样品拥有分歧的沟槽纹理，而腕足类茎部化石则显示出优先的纹理各向同性。详细而精确的三维表面扫描被证明是古生物学家和地质学家研究生命进化和化石形成的理想工具。</span></p><p><span style="color: var( --e-global-color-text ); background-color: rgba(255, 255, 255, 0);">这里显示的数据只代表了分析软件中的一部分计算结果。NANOVEA轮廓仪几乎可以测量任何领域的表面，包括半导体、微电子、太阳能、光纤、汽车、航空航天、冶金、加工、涂层、制药、生物医学、环境和许多其他领域。</span></p>								</div>
