| 摘 要： | 选择四种不同脱氧程度的碳钢,在pH=10的3%(质量分数)NaCl溶液中进行极化试验,比较钢的点蚀诱发敏感性;在人造海水中进行模拟闭塞腐蚀电池试验和室内挂片试验,评价钢的点蚀扩展速度.结果表明:沸腾钢A,B钢中的主要夹杂物为橄榄状硫化物和土豆状氧化锰夹杂,镇静钢C,D钢的主要夹杂物为条片状硫化物夹杂和硅酸盐夹杂.在相同条件下,沸腾钢比镇静钢表现出更弱的点蚀诱发敏感性和更小的点蚀扩展速度.同是镇静钢,过低的磷含量可显著促进蚀孔的扩展.

| Abstract: | Four carbon steels with different deoxidization degrees had been selected.Pitting susceptibility of steel was compared by means of polarization tests in 3%NaCl with pH=10.The ability to propagate of pits was evaluated by occluded corrosion cell and hanging plates.The results showed the main inclusions in steel A and steel B were olivelike sulphide and MnO,while the typical inclusions in steel C and steel D were the strip-like silicate and sulphide inclusions,respectively.Under the same condition,the killed ... |
