9610440科尔本研究的目的是开发实验技术和预测性的理论理解所需的工程涂层，优化用于基本的机械部件，如轴承和齿轮。 研究的第一步是设计等轴涂层，这些涂层有望比目前的柱状结构具有更好的面内强度。 所提出的处理技术涉及涂层的再成核和/或高电流、低能量离子轰击。 这些涂层的机械和物理性能及其接触疲劳抗力将被确定，并与微观结构相关。 将开发理论模型来解释相关性并将其推广。 ***

9610440 Keer The purpose of this study is to develop the experimental techniques and predictive theoretical understanding needed to engineer coatings that are optimized for use on basic mechanical components such as bearings and gears. The first step of the study is to engineer equiaxed coatings which are expected to have better in-plane strength than the current columnar structure. The proposed processing technique involves renucleation of coating layers and/or high current, low energy ion bombardment. The mechanical and physical properties of these coatings and their contact fatigue resistance will be determined and correlated with microstructure. Theoretical models will be developed to account for the correlations and to generalize them. ***
