Low friction and wear resistant coatings are critical for increasing life cycles, lowering maintenance costs, and reduced environmental impact of engineering systems. This application outlines the need for purchase of a depth-sensing nanoindenter that will be used to evaluate new coatings developed for improved friction and wear performance. Two types of coatings will be examined: ultra-thin polymer-based nanocomposite coatings and boronized steel coatings covered with a thin layer of boron nitride. The depth-sensing nanoindenter will be used to examine the mechanical properties of these coatings, which is intrinsically linked with the wear resistance capabilities of the coatings. While friction performance is less clear, correlated measurements with tribometers (for friction performance evaluation), atomic force microscopy, and rheology will allow for interdisciplinary interpretation of the results, making the relationship between mechanical properties and material structure revealed through depth-sensing nanoindentation measurements more meaningful in applications. The proposed indenter will be housed in a collaborative laboratory within the Schulich School of Engineering at the University of Calgary, and be used in the training of highly qualified personnel throughout the school. Additionally, the proposed equipment will be used to bridge the gap between the evaluation of materials for industrial applications in heat exchanges, typically performed with tribometers, microindentation, and rheology, to the fundamental material structure-property relationships that can be accessed through nanoscale inquiry using atomic force microscopy, atomistic simulations, and electron microscopy, thus unifying both fundamental research and innovation arms of scientific investigation.

低摩擦和耐磨涂层对于延长生命周期、降低维护成本和减少工程系统的环境影响至关重要。该应用程序概述了购买深度传感纳米压痕仪的需求，该压痕仪将用于评估为改善摩擦和磨损性能而开发的新涂层。将研究两种类型的涂层：超薄聚合物基纳米复合涂层和覆盖有氮化硼薄层的硼化钢涂层。深度传感纳米压痕仪将用于检查这些涂层的机械性能，这与涂层的耐磨性能有着内在的联系。虽然摩擦性能不太清楚，但与摩擦计（用于摩擦性能评估），原子力显微镜和流变学相关的测量将允许对结果进行跨学科的解释，使得通过深度传感纳米压痕测量揭示的机械性能和材料结构之间的关系在应用中更有意义。拟议的压头将被安置在卡尔加里大学Schulich工程学院的一个合作实验室内，并用于整个学校的高素质人员的培训。 此外，所提出的设备将用于弥合热交换中工业应用材料的评估（通常使用摩擦计、微压痕和流变学进行）与基本材料结构-性能关系之间的差距，基本材料结构-性能关系可以通过使用原子力显微镜、原子模拟和电子显微镜的纳米级查询来访问。把基础研究和科学研究的创新两个方面统一起来。
