摘　　要：选取碳钢和微弧氧化船用钛合金材料制成试样,通过绝缘性能试验、盐雾加速腐蚀试验和耐磨性试验等来研究海洋环境下碳钢和船用钛合金的腐蚀行为。研究结果表明:在未装配微弧氧化船用钛合金材料的情况下,试样的失质量为0.007 0 kg;装配微弧氧化船用钛合金材料后,试样的失质量为0.006 5 kg。两种情况下试样失质量无明显差异,说明装配微弧氧化船用钛合金材料没有加速碳钢的腐蚀。经微弧氧化后的钛合金材料绝缘性能优良,可与碳钢材料构件组合使用,但其耐磨性能有限,必须与绝缘垫圈或垫片配合使用。The carbon steel and micro-arc oxidation marine titanium alloy materials were selected assamples. The corrosion behaviors of carbon steel and marine titanium alloy in marine environments werestudied through insulation performance tests, salt spray accelerated corrosion tests, and abrasion resistancetests. The results show that the mass loss of the sample is 0.007 0 kg without the use of micro-arc oxidationmarine titanium alloy. Micro-arc oxidation marine titanium alloy material is assembled, the mass loss of thesample is 0.0065 kg. Since there is no significant difference in the mass loss of the sample in both cases, itindicates that the assembly of micro-arc oxidation marine titanium alloy material does not accelerate thecorrosion of carbon steel . The titanium alloy material oxidized by micro -arc has excellent insulationproperties, so it can be used in combination with carbon steel members, however due to its limited abrasionresistance, it must be used in conjunction with insulating washer or gaskets.
