【摘要】 用埋设试件的方法，研究了１Ｃｒ１３、１Ｃｒ１８Ｎｉ９Ｔｉ两种不锈钢在酸性、中性及碱性土壤中经过１、３、５年三个试验周期后的腐蚀特征．结果表明，两种不锈钢在酸性及中性土壤中腐蚀轻微，在高盐碱性土壤中腐蚀严重，以点蚀为主，其中１Ｃｒ１８Ｎｉ９Ｔｉ耐蚀性优于１Ｃｒ１３．土壤中Ｃｌ－及ＳＯ２－４是影响不锈钢腐蚀的主要因素，土壤ＰＨ值也是影响不锈钢腐蚀的重要因素，且自然腐蚀电位越负，腐蚀越严重．更多还原

【Abstract】 Corrosion behavior of 1Cr13 and 1Cr18Ni9Ti in soils were studied.The results showed that corrosion of stainless steels was mainly due to the contents of Cl - and SO 2- 4 in soils, and there was a good correlation between the weight loss of corrosion and the contents of Cl - and SO 2- 4 in soils.The pH of soils and corrosion potential were other important factors determining the corrosion rate of the stainless steels in soils.Some severe pitings of 1Cr13 were observed in alkaline soils.更多还原
