Abstract The main objective of this work is to model wear a disc which was subjected dry contact with ball in unidirectional sliding. Tribological tests sliding pairs were carried out using tribological tester T-11 ball-on configuration. Stationary balls made 100Cr6 steel hardness 62 ± 2 HRC co-acted rotating discs 42CrMo4 40 2HRC. Discs machined by lapping, grinding, milling, and vapour blasti...

In this study, the deposition of martensitic stainless-steel (Metco 42C) powder on 42CrMo4 structural steel by direct laser (DLD) was investigated. Clads were produced varying power, scanning speed, feed rate, and preheating. The effect these processing variables microstructure microhardness clads analyzed, as well their soundness, yield (measured dilution), geometric characteristics (height, w...
