THE STRUCTURE AND PROPERTIES OF 2Cr13 STEEL STRENGTHENED BY LASER SURFACE ALLOYING

It is the purpose to improve surface properties of 2Cr13 steel with laser surface alloying. In different parameters of technology, observing microscopic structure strengthened by laser surface alloying with a scanning electron microscopy and measuring microhardness strengthened by laser surface alloying with a microsclerometer. Result in laser surface alloying can greatly strengthen hardness and hardwearing of 2Cr13 steel surface, and develop application of 2Cr13 steel.
