Effects of preparation technique for MK-5 material on frictional and wear response

A study has been made on how the method of making a tribotechnical material affects the frictional and wear behavior. The materials have been made from identical initial powders, which corresponded in composition to standard MK-5 powder material, but different methods were used: traditional sintering under pressure and plasma spraying. The tribological properties of material made by plasma spraying are better than those of ones made by the traditional method, because of the presence of oxides formed during the spraying.
