Abstract

In the present study samples of AISI 4140 steel pre-treated by plasma nitriding and coated by a hydrogen-free hard carbon film were investigated with respect to microhardness, surface roughness, residual stress, scratch adhesion and dry sliding wear resistance. To examine the influence of the nitrided zone on the performance of the coating-substrate composite, the coating was deposited on hardened as well as on plasma nitrided samples, nitrided under two different nitriding conditions.

Wear tests showed that in all cases a hydrogen-free hard carbon coating produced a reduction in the coefficient of friction of about one order of magnitude. Wear scar profiling and weight loss calculations showed that the wear resistance of the duplex treated steel was dramatically improved compared to uncoated steel. It was also found that nitriding of the substrate improves the wear resistance of the hydrogen-free hard carbon coating compared to the coating deposited on a hardened substrate.
