Studying the properties of the nitrided layer steel ШХ 15 and its wear in abrasive environments.
Abstract
Experimental study of the properties of the surface layer of steel SHH15 after ion nitriding among the mixture of nitrogen and argon in their different ratios for different technological regimes. Investigated thickness, hardness, wear resistance and phase composition of the nitrided layers. Studies were conducted on the durability of the machine mechanical friction at specific load 0,5 MPa and slip speed 1,32 m / s in the environment model abrasive solution. On the basis of the plan of experiments investigated the analytical properties depending on the technological parameters of the process of ion nitriding. Constructed graphic dependence of the nitrided layer thickness and hardness of the surface of the technological parameters of the process of ion nitriding. The kinetics of the process of wear of the nitrided layers in the model abrasive solution. Conducted comparing the intensity of wear steel SHH15 after quenching and ion nitriding. An optimization study properties of the nitrided layer by setting the maximum hardness of the surface, the thickness of the hardened layer and its durability. Found optimum conditions of ion nitriding steel SHH15 for each of the studied characteristics. Established that the wear resistance of steel SHH15 after ion nitriding 2,5 times higher compared to its durability after quenching.References
