摘要:
通过T2纯铜和1060纯铝在R22制冷剂和5％的HCI、H2SO4、NaOH、NaCl溶液中的纯腐蚀和电偶腐蚀实验,比较了铜和铝的腐蚀特性.结果表明铜在各介质中腐蚀速度都相当低,表现出良好的耐蚀性,而铝在这5种介质中的纯腐蚀速度差别巨大.铝在制冷剂R22中表现出了与铜相似的耐蚀性,腐蚀速度只有0.041 mm·a-1.在NaCl中的腐蚀速度也较低,为0.063 mm·a-1.但在HCl和NaOH中腐蚀极严重.铜-铝电偶腐蚀结果表明铝被加速腐蚀,而铜的腐蚀过程受到抑制.铝可以代替铜作为冰箱换热器材料,但应进行必要的表面涂覆处理.
Abstract:
The corrosion behaviours of T2 copper and 1060 aluminum are compared via pure corrosion and gal.vanic corrosion test in R22 refrigerant and $% HCl, H,$O,, NaOH, and NaCl solution. The results show thatthe pure corrosion speed of copper in all these media is quite low, showing good corrosion resistance, mean.while the pure corrosion speed of aluminum in these media is of great difference, Aluminum in R22 refrigerantshows similar corrosion resistance to copper, and the corrosion speed is only 0. 041 mm a-1. The corrosionspeed in NaCl is 0. 063 mm · a-1. However, the corosion of aluminum in HCl and NaOH is catastrophie.T’he results of copper-aluminum galvanic corrosion show that the corrosion of aluminum is accelerated and thecorrosion of copper is inhibited. Aluminum can replace copper as refrigerator heat exchanger materials, butsurface coating treatment is necessary.
