Abstract

A modified ASTM G 65 rubber wheel test was used in wet and dry conditions using 220 nm titania particles and 368 μm sand particles, respectively. Both tests were conducted on WC-CoCr coatings produced with two powders varying in carbide grain size; conventional and sub-micron, to address the effect of carbide size, as well as abrasive medium characteristics on the wear performance. The same spot with low and high magnification before and after abrasion wear test was analysed in detail using SEM to visualize wear mechanism. It was shown that the mechanism of the wear depends on the relative size of the carbide and abrasive particle. Quantitative analysis of wear also was done on the samples. By tailoring the carbide size the wear performance can be improved. Some of the mechanical properties of coatings were evaluated for comparison purposes.
