High power diode laser surface hardening of U74 rail steel

WANG Zhi-yong,SU Guo-qiang,ZHANG Hui,ZUO Tie-chuan(National Center of Laser Technology,College of Laser Engineering at Beijing University of Technology,Beijing 100022,China)  
A new kind of high power diode laser was developed in surface hardening on U74 rail steel.The results show that the grain of the rail steel is refined,and that the hardness HV10/20 of the harden layer increases to 800~900,which is 3 to 4 times higher than that of the base steel.There is different between feed direction along fast beam axis and slow beam axis.The harden layer is deeper when scan along slow beam direction,as well as the hardness fall down rapidly within the transition zone.The efficiency of surface hardening along slow axis is 4 times than that along fast axis.
