对热喷涂底锌面铝复合涂层与铝涂层做了耐硫化物应力腐蚀的对比试验．试验结果表明：锌铝复合涂层并没有保持锌、铝的各自优点，改善原来的不足；相反，在底锌面铝复合涂层中，由于腐蚀介质渗透到底锌层，使锌层优先溶解，导致面铝层开裂脱落，进而使整个涂层失效．同时，探讨了锌铝复合涂层在ＮＡＣＥ的标准饱和Ｈ２Ｓ水溶液的应力腐蚀失效过程，指出了热喷涂锌铝复合层设计的不合理性．
A comparison test on the stress corrosion resistance of sulfide coated with aluminum coating on the thermal sprayed zinc-bottom aluminum composite coating and the aluminum coating was carried out. The experimental results show that the zinc-aluminum composite coating does not maintain the respective advantages of zinc and aluminum and improves the original deficiencies. On the contrary, in the bottom zinc-aluminum composite coating, the zinc layer dissolves preferentially due to the infiltration of the corrosive medium into the bottom zinc layer, Resulting in aluminum surface cracking off, leaving the entire coating failure. At the same time, the stress corrosion failure process of zinc-aluminum composite coating in standard saturated H2S aqueous solution of NACE was discussed, and the irrationality of thermal sprayed Zn-Al composite layer design was pointed out.
