摘要: <正> 一、前言 马氏体时效不锈钢采用超低碳基体的高合金化,利用在韧性为的Fe-Ni板条马氏体基体中大量析出金属间化合物,从而保证了它在获得超高强度的同时仍具有足够的韧性。正因为该类钢的这一突出优点、使得人们的研究一直侧重于其机械性能和强化机理,而忽略了对其耐蚀性的进一步探讨。本文作者试图从热处理入手,就其对该类钢钝化特性的影响进行一些有意义的探索,为改善其耐蚀性提供一定的参考。
Abstract:The passive property of new type maraging stainless steel 0 Crl2Ni5MnMoCuAlTiREB is researched in the passive state formation, the stability, and localized damage of passive film by means of various electrochemical detection methods and TEM. The results show that the passive pioperty of the steel in solid solution state is not so good and it can be improved by short time aging. After a long time aging, the passive property will gradually lower again because of the precipitation of intermetallic compound. Optimum stability of passive film is obtained with proper heat treatment, but the critical passive current density i. is larger. Deformation in solid solution state decreases the stability of passive film formed on aged steel, but hardly affects the pitting breakdown potential φ_b.
