Abstract

This paper reviews the behaviour of CVD diamond coatings when subjected to solid particle erosion. The high hardness, elastic modulus and strength of diamond coatings make them attractive options for use in components employed in erosive environments. Nevertheless, despite the disparity in properties between diamond and many common erodents such as silica, which can result in extensive damage to the impacting particles, repeated particle impacts can generate damage to the coating resulting in sudden and catastrophic failure. The factors affecting the erosion behaviour of diamond coatings are described, as well as the common features of erosion damage in diamond coatings, together with the mechanisms by which they were formed. Such understanding can assist in the design of coated components for use in erosive environments.
