The Influence of Laser Hardening on the Microstructure and Wear Resistance of Disk Opener

Abstract:

Article Preview

The microstructure and properties of hardened layer of 45 steel disk opener with a variety of parameters of HLD1001.5 solid-state laser were studied by SEM, Rockwell hardness tester and wear tester. The results showed that under the conditions of the laser power from 400W to 600W, the hardened layer is composed of melted zone, phase transformation zone and heat affected zone, and the hardness is up to 58.5-61HRC, and the disk openers have excellent wear resistance after the laser hardening, which is best in the disk opener with the treatment of laser power 500W.
