چکیده انگلیسی
The behaviour of the resulting laser claddings was thoroughly evaluated up to 600â¯Â°C, including the oxidation behaviour and reciprocating tribotesting using different counter body geometries (ball and flat pin). The self-lubricating coatings showed lower friction than the unmodified reference alloy at all tested temperatures, in addition to a significant microstructural stability after prolonged exposure at high temperatures. The addition of solid lubricants to the claddings was also found to be beneficial in terms of the counter body wear at HT, as no material loss could be measured for the bearing balls after testing at 600â¯Â°C against the self-lubricating claddings, despite the significant softening experienced by AISI 52100 bearing steel at HT.
