The Influence of the Thermomagnetic Treatments on the Hardness Number of Steels and the Superficial Layers Nitrided Durability
Keywords:
thermomagnetic treatements, hardness number, wear process, durability
Abstract
Two types of steels subjected to a nitriding thermo-chemical treatment after thermomagnetic treatments. The structural aspects into superficial layer of these steels are studied during friction process by using of an Amsler machine, taking two sliding degrees, different contact pressures and testing time. I tried to determine the durability of these materials, the surface structure evolution at different tests after thermomagnetic treatments.
