渗硼硬化法是一种从钢材表面渗入硼,并使之扩散形成表面硬化层的新工艺。利用这种方法可以获得非常坚硬的表面硬化层(Hv高达1400～2000)。该硬化层具有优异的耐磨性,直到目前为止还没有一种可以与它相比拟的理想的硬化方法。该硬化层还具有优良的耐腐蚀性和耐氧化性;由于此工艺不必进行淬火等热处理,因此不会产生渗碳的变形和裂纹等弊病。所 Boron hardening method is a new technology that infiltrates into the steel from the surface of steel and makes it diffuse to form a hardfacing layer. Using this method can be very hard case hardened layer (Hv up to 1400 ~ 2000). The hardened layer has excellent abrasion resistance, and so far no ideal hardening method comparable to it has been found. The hardened layer also has excellent corrosion resistance and oxidation resistance; as the process does not require quenching and other heat treatment, it does not produce carburizing deformation and cracking defects.
