This study was chosen for the 40Cr matrix materials, use of the HL-1500 helium-free cross-flow CO2 laser processing machine to its surface to carry out large areas of laser transformation hardening processing, analysis of different process parameters obtained under the conditions of the surface material and performance. The results showed that: a large area laser transformation hardening by the main martensite, a small amount of residual austenite, Technology for 1.5mm lap, lap than the technology-1mm to reduce the wear and tear when 0.0752g, to increase the maximum hardness The HK 162.8.
