Laser cladding technology capable of prolonging life of H13 hot forging die

Abstract

The invention discloses a laser cladding technology capable of prolonging the life of an H13 hot forging die. The laser cladding technology includes the specific steps that firstly, the H13 hot forging die is pretreated at the temperature of 300 DEG C to 400 DEG C; and then the laser cladding technology is adopted for cladding the surface of the die with cobalt-based alloy powder. According to the laser cladding technology capable of prolonging the life of the H13 hot forging die, laser cladding of the Co-based alloy power is conducted on the work face of the H13 hot forging die, the Co-based alloy powder and a die base body form a metallurgical bonding state, the H13 hot forging die can obtain performance of high temperature resistance, extrusion resistance, wear resistance, crack resistance, collapse resistance and the like, the fatigue rate of the die is reduced, the service life of the die is prolonged by one or more times, the cost of the die is reduced by 50%, the die changing downtime is shortened, and the production efficiency is improved.

Description

technical field [0001] The invention relates to a surface treatment process of an H13 hot forging die, in particular to a laser cladding technology for improving the service life of the H13 hot forging die. Background technique [0002] The working conditions of the H13 hot forging die are relatively harsh, and the working surface of the die is easily damaged by the roughening of the workpiece. The traditional quenching and tempering treatment methods in the past cannot overcome the above defects, resulting in the H13 hot forging die being easily damaged and having a short service life. , The precision of the products produced is poor. Contents of the invention [0003] In order to make up for the above deficiencies, the present invention provides a laser cladding technology for improving the life of the H13 hot forging die, which effectively prolongs the life of the H13 hot forging die. [0004] The technical scheme adopted by the present invention in order to solve the ...
