In this paper, the structure of nitrided titanium on carbon steel is studied, the interaction mechanism of nitrided titanium is analyzed, and the orthogonal process design of nitrided titanium is given. The mechanical properties of nitrided layer in different depth were studied, and the microstructure and mechanical properties of nitrided layer under different temperature and nitrogen-hydrogen ratio were analyzed. The microstructure, surface morphology, wear marks and element composition of the nitrided layer were observed and analyzed by means of Om, XRD, SEM and EDS, and the gradient hardness distribution, friction and wear properties of nitrided layer were tested and analyzed.

Electric Field Heat treatment has a significant effect on the superplasticity, recrystallization and phase transformation of metals, and can also improve the superplasticity and mechanical properties of materials. The effect of electric field on high temperature decarburization of high carbon steel was studied by comparing the decarburization degree of high carbon steel under electric field and non-electric field. The mechanism of the electric field is analyzed. The Electric Field promotes the migration of vacancy or vacancy + solute atoms to the grain boundary, dislocation or sample surface to realize the diffusion process.
