摘要
奥氏体不锈钢是一种应用非常广泛的金属耐蚀材料,但强度较低,影响了它的使用寿命。长期以来,其表面强化与耐蚀性能之间的矛盾一直未能根本解决。本文综合评述了一种近年来发展较快的不影响奥氏体不锈钢耐蚀性能的表面强化工艺--奥氏体不锈钢低温渗碳技术,论述了该技术的工艺特点,探讨了该技术的强化原理,并预测了它的发展前景。
Austenite stainless steels are widely applied as a metal corrosion resistance material, but the properties of low surface strength influence its service life. Contradiction between surface enhancement and corrosion resistance hadn＇t been thoroughly solved so far. In this paper a fast developing method is made comprehensive review for hardening surface of austenite stainless steels without any reduction of corrosion resistance,which is called austenite stainless steels low temperature carburizing. The process features is described, the strengthening mechanism discussed and its prospect is forecasted also.
