摘　　要：采用浸泡试验和慢线性电位扫描测量阳极极化曲线等方法,以304、316L不锈钢及45CT喷涂层为参照,研究了666非晶丝材在HCl(1mol/L)和Na Cl(w=3.5%)溶液中的腐蚀质量损失和电化学腐蚀行为,以及过氧化氢溶液液滴在四种涂层表面的氧化腐蚀特性。结果表明:在Na Cl和HCl溶液中,抗蚀能力排序为666非晶丝材>45CT>316L>304,666非晶覆盖层在HCl及Na Cl中的腐蚀速度较小,耐腐蚀性能亦佳;在过氧化氢溶液液滴表面的氧化腐蚀实验中,其抗氧化腐蚀的能力排序仍然为666非晶丝材>45CT>316L>304。由此可知,666非晶电弧喷涂丝材在酸性、中性和强氧化性介质中有明显的抗蚀效果。The corrosion mass loss and electrochemical corrosion behavior of iron-based amorphous spraying 666 typing coating in chlorhydric acid and NaCl solutions were investigated by immersion tests and implementing anodic polarization measurements; while oxidation corrosion properties in four kinds of coatings were studied by hydrogen peroxide droplets.The results show that 666 typing has better corrosion resistance in NaCl, HCl solutions and hydrogen peroxide droplets than304, 316 L and 45 CT. The comparative sequence of corrosion resistance in chlorhydric acid, NaCl solutions and hydrogen peroxide droplets can be expressed as 666〉45CT 〉316L〉304. In summary, iron-based amorphous spraying 666 typing coating improves the corrosion resistance of substrate in chlorhydric acid, NaCl solutions and hydrogen peroxide droplets.
