摘要为提高1Cr18Ni9Ti不锈钢在NaCl和酸溶液环境中的耐磨损性能，利用等离子喷涂制备两种晶粒WC-10Co-4Cr涂层，研究其在3.5%（质量分数，下同）NaCl溶液与酸溶液（pH=5.0）中的耐腐蚀性能。结果表明：涂层中含有WC，W₂C，W以及η相（Co_xW_xC）。两种涂层在3.5% NaCl溶液中的腐蚀电位均高于1Cr18Ni9Ti基体的腐蚀电位。在不同温度酸溶液（pH=5.0）中，纳米WC-10Co-4Cr涂层的电位差随温度的变化最小。涂层在NaCl和酸溶液中腐蚀机制分别为：WC-10Co-4Cr涂层表面吸附氧粒子与涂层中的Co和WC在3.5% NaCl溶液中形成电偶；在酸溶液中（pH=5.0），涂层中的Co溶解形成Co²⁺离子，和WC相直接形成电偶腐蚀，导致涂层表面出现孤立的WC颗粒。

Abstract：In order to improve the wear resistance of 1Cr18Ni9Ti stainless steel in NaCl and acid solution environment, the WC-10Co-4Cr coatings with two grain sizes were prepared by plasma spraying, and the corrosion resistance in 3.5%(mass fraction, the same below)NaCl and acid solution(pH=5.0) were investigated. The results show that the WC, W₂C, W and η (Co_xW_xC) exist in these coatings. The corrosion potential of these coatings is higher than that of 1Cr18Ni9Ti substrate in 3.5% NaCl solution. In the acid solution (pH=5.0) at different temperatures, the potential difference for the nanometer WC-10Co-4Cr coatings has little change with the temperature. The corrosion mechanism of the coatings in NaCl and acid solution is shown as follows:the oxygen atoms adsorbed on the surface of WC-10Co-4Cr coating, can impel the Co and WC to form the galvanic couple in 3.5% NaCl solution. In the acid solution (pH=5.0), Co phase in the WC-10Co-4Cr coatings is dissolved to Co²⁺, and formed the galvanic corrosion with WC phase, so the isolated WC particles are formed on the coating surface.

Key words： electrochemical corrosion WC-10Co-4Cr plasma spraying salt solution acid solution
