Tribological Behaviour of Nitrocarburized Superficial Layer after Thermo-Magnetic Treatments Applied to Steels, During Friction Process
Keywords:
thermomagnetic treatments, tribosystem, tribomodel, superficial layer
Abstract
Two types of steels subjected to a nitrocarburized thermo-chemical treatment after thermomagnetic treatments. The contact problems are studied employing the concept of tribosystem and tribomodel. 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. The performed tests allowed establishing the influence of the thermal, magnetic and mechanical parameters on behaviour of these two steels taking in study during friction process.
