Coefficient of friction and wear of sputtered a-C thin coatings containing Mo
Original language description
The paper reports on preparation of ~3000 nm thick a-C coatings containing Mo, interrelationships between their mechanical properties, a coefficient of friction and wear rate and the effect of Mo content in the a-C coating on these interrelationships. The Mo-C coatings were prepared by sputtering using an unbalanced magnetron (UM) equipped with a graphite targets (diameter 100 mm, 99.9 % purity) fixed to the UM cathode with Mo ring of different inner diameter. The content of Mo in the a-C coating was controlled by inner diameter of Mo ring. It is shown that coefficient of friction and wear rate of the coating strongly depend not only on its hardness H but also on its effective Young's modulus E*, the ratios H/E*, H^3/E*^2 and the elastic recovery. Theratio H^3/E*^2 characterizes the resistance of coating to plastic deformation. Coatings with a low amount of Mo composed of nanograins of carbides dispersed in a-C matrix exhibit low values of coefficient of friction 0.07 and wear rate 10
