Abstract
<p>This paper presents wear behavior of the plasma nitride 42CrMo4 steel. This steel is used in mechanical industry; it has been assessed by evaluating tribological properties and surface hardness by using a pin-on-disk wear machine and microhardness tester. Experimental results showed that the nitrides ε-Fe<sub>2-3</sub>N and γ’-Fe<sub>4</sub>N present in the compound layer increase the microhardness. It is found that plasma nitriding improves the wear rate and the presence of a hard and brittle compound layer on the surface causes an increase in wear of the specimen surface.</p>
