A GOALI award supports studies of the microstructure, mechanical properties, and tribological behavior of thermal spray functionally graded coatings. The university team will study the fundamental behavior of the coatings and coordinate with the two industrial partners who will prepare the coatings and test them under bench and field conditions. Two families of coatings will be studied - hard wear resistant WC-Co coatings produced by Caterpillar, and abradable MCrAlY coatings for high temperature sealing applications produced by Solar Turbines.

GOALI奖支持热喷涂功能梯度涂层的微观结构、机械性能和摩擦学行为的研究。 大学团队将研究涂层的基本行为，并与两个工业合作伙伴协调，他们将准备涂层并在实验室和现场条件下进行测试。 将研究两类涂层--卡特彼勒生产的硬质耐磨WC-Co涂层和Solar Turbines生产的用于高温密封应用的耐磨MCrAlY涂层。
