Hard coke

The results indicate that the hard carbides coating on low cost steel surfaceare alloyed by laser, it can essentially change the chemical composition of steel surface, greatlyenhance its hardness and anti-abrasion property, and improve the mechnical properties of carbonsteel surface.

结果表明:利用激光在低质钢材表面涂覆高性能的硬质碳化物,经激光合金化处理之后,能使低质钢材表面化学成份发生根本性变化,硬度和耐磨性能均有较大的提高。
