| Abstract: | Surface hardening of 1Cr18Ni9Ti steel dies by liquid borating is investigated and the optimized processing parameters for borating have been obtained. It was showed that there was a Fe2B layer on the hardened surface of the dies and the hardness of the surface was up to Hvl450, and wear-resistance was greatly improved. The matrix mi-crostructure was austemite so that non-magnetic property was assured. The application of the dies showed that the service life after the borating was increased by three times. |
