淬火淬火quenching将金属工件加热到某一适当温度并保持一段时间,随即浸入淬冷介质中快速冷却的金属热处理工艺。常用的淬冷介质有盐水、水、矿物油、空气等。淬火可以提高金属工件的硬度及耐磨性,因而广泛用于各种工、模、量具及要求表面耐磨的零件(如齿轮、轧辊、渗碳零件等)。通过淬火与不同温度的回火配合,可以大幅度提高金属的强度、韧性及疲劳强度,并可获得这些性能之间的配合(综合机械性能)以满足不同的使用要求。另外淬火还可使一些特殊性能的钢获得一定的物理化学性能,如淬火使永磁钢增强其铁磁性、不锈钢提高其耐蚀性等。淬火工艺主要用于钢件。常用的钢在加热到临界温度以上时,原有在室温下的组织将全部或大部转变为奥氏体。随后将钢浸入水或油中快速冷却,奥氏体即转变为马氏体。与钢中其他组织相比,马氏体硬度最高。钢淬火的目的就是为了使它的组织全部或大部转变为马氏体,获得高硬度,然后在适当温度下回火,使工件具有预期的性能。淬火时的快速冷却会使工件内部产生内应力,当其大到一定程度时工件便会发生扭曲变形甚至开裂。为此必须选择合适的冷却方法。根据冷却方法,淬火工艺分为单液淬火、双介质淬火、马氏体分级淬火和贝氏体等温淬火4类。
