| 摘 要： | 采用电化学极化和失重法研究了纯铜管、304不锈钢管于开口、低氧密闭两种状态下在不同浓度氨溶液中的腐蚀性能.结果表明:304不锈钢管的耐氨蚀性能明显优于纯铜管;溶解氧是影响氨蚀的关键因素,但对铜、304不锈钢的影响不同,促进铜管的腐蚀却能抑制304不锈钢的腐蚀;氨浓度也是影响氨蚀的重要因素,但在氧充足条件下对304不锈钢的腐蚀影响甚微.

| Abstract: | The corrosion performance of tubes of copper and 304 stainless steel in ammonia solutions with different ammonia concentration are studied by electrochemical polarization and weight-loss method.The test conditions include:in open atmosphere and in airtight solution being short of O2.It shows that 304 stainless steel tubes possesses much better corrosion resistance rather than copper tubes in ammonia solution.Dissolved oxygen is the key factor which affects ammonia corrosion,which has different impacts on co... |
