CHANGE OF WEAR RESISTANCE OF STEEL 45 AT THE MAGNETRON SPUTTERING OF CU-BASED THIN ANTIFRICTION FILMS
In the present work., the effect of a thin-layer antifriction coating based on copper deposited by magnetron sputtering on a sample of steel 45 on the wear resistance during the runningin period in the friction pair "steel 45 - steel ШХ15" is studied. Comparison is made with a sample of steel 45 without applied antifriction coating. Using the Jeol JCM-5700 scanning electron microscope, the elemental composition of the thin-layer coating was studied before and after the period of workingin of samples. The study found that the coated sample, compared with the uncoated sample, has a lower friction moment during the runningin period and a much shorter runningin time, as well as lower mass wear.
