Multi-ion beam (MIB) surface modification techniques are used to treat Cr12MoV cold die work steel. The modified layers of steel treated by MIB is improved with low friction coefficient, high wearing resistance and strong adhesion with the matrix through results of hardness, scratch and wearing test. The modified layers include (Ti2N +TiN), (а-Fe+TiN) and (а- Fe(N)+Cr7C3) three layers from surface to inside by analysis of SEM, EPMA and TEM. And the surface layer presents nano-size grain refining. The service life of the Cr12MoV cold die steel treated by MIB can be prolonged 3-5 times longer than the untreated one.

Metal Arc Welding

The influence of welding heat input on the microstructure and mechanical properties of 5Cr5MoV die steel was studied in order to improve the mechanical properties of the cold working die and extend its service life. Shielded metal arc welding (SMAW) method was used with different heat inputs in the range from 4.2 to 6.61 kJ/cm to repair the 5Cr5MoV die steel. Microhardness and tensile properties were performed to evaluate the repaired quality of the cold working die steel. The microhardness of the weld repaired zone gradually decreased from the weld to the tempering zone. The highest microhardness in the weld repaired zone was 863 HV, and finally, it decreased to about 300 HV. With the increase of heat input, the tensile strength of the weld and the heat affected zone increased; nevertheless, the tensile strength of the tempering zone increased first and then decreased. As a result, 6.6 kJ/cm is the best value of heat input judged from the microhardness distribution and the tensile properties.
