Sliding friction behavior of HVOF sprayed hardmetal coatings under different load conditions
Original language description
The HVOF sprayed hardmetal coatings, thanks to the combination of hard particles and tough matrix, show superior behavior in applications requiring the wear resistance. Among other types of wear, sliding friction and wear behavior is one of the most common. In dependence on application, the working conditions varied in terms of load, velocity, temperature, lubrication etc. In the paper, the influence of load condition on the sliding friction and wear behavior of the WC-based and CrC-based HVOF sprayed hardmetal coating was studied using four different friction and wear tests: ASTM G 99 (Pin-on-disc test), ASTM G 77 (Block -on-ring test), ASTM D5707 (SVR test) and high loaded friction wear test (Pin-on-cylinder test). Several types of lubricants were used to compare the dry and lubricated sliding friction and to study the lubricants influence of the coefficient of friction and wear of selected coatings with respect to the load conditions. Based on the results, the suitability of the WC-
