| 摘 要： | 采用极化曲线、盐雾试验和自然暴晒等方法,研究了热喷涂Al或Zn层在3%NaCl溶液、西安工业区降水(相当于酸雨)和海南海洋大气条件下的耐腐蚀性能。提出了喷涂层出现不同面积剥落时的腐蚀速率和低碳钢基体允许裸露的平均面积比率,为设备在不同地区和不同使用寿命要求下的涂装工艺设计、使用维护提供依据。

| 关 键 词： | 热喷涂 腐蚀性 腐蚀速率 裸露面积 |

| Abstract: | Corrosion resistance of thermal sprayed Al or Zn coatings on steel in 3% sodium chloride solution,snow water(equivalent to acid rain) and marine environment in Hainan island was examined by means of electrochemical measuements,salt spray tests and exposure in atmosphere.The average corrosion rate of coatings with a certain area of bare steel was obtained.These results could be applied to design and maintainance of coating systems in various places and with various demands for life-span. |

| Keywords: | Thermal spray Corrosion-resistance Bare area Corrosion rate |
