| Abstract: | In order to prolong the life span of a diesel cylinder, this article analysed the shortage of high frequency quenching technology and the surface strengthening of diesel cylinder by laser. The new method of laser treatment was used to harden the cylinder and a netlike induration strap was formed as a result of laser scanning. The experimental study indicates that the life span would be increased by 7 times if the induration straps have a distance of 3 mm between two straps and strap width less than 2 5 mm, depth less than 0 25 mm, which were formed by laser with input power 1 200 W and spot diameter 3 mm. |
