摘　　要：对耐热不锈钢 ( 1Cr1 1Ni2W2MoV、Cr1 7Ni2 )和钛合金 (TA7) ,在 3.5%NaCl水溶液中的电偶腐蚀敏感性进行了评价。研究了试样表面状态和阴阳极面积比对两类材料接触腐蚀行为的影响规律 ,探讨了腐蚀机理。The susceptibility of the galvanic corrosion for titanium\|alloy (TA7) coupled to heat\|resistant stainless steels (1Cr11Ni2W2MoV and Cr17Ni2) in 3.5% NaCl solution was estimated. The effect of the surface states and cathode\|anode area ratios (Ac/Aa) on the behavior of galvanic corrosion for the two kinds of materials and the corrosion mechanisms were studied.
