CORROSION AND COUNTERMEASURES ON AUTOMOBILE AND ITS MATERIALS
汽车用其用材的腐蚀与对策：中国·瑞典10年合作研究

In a co-operative Chinese-Swedish research project an investigation on the cor- rosion status of 2000 trucks and buses in China and Sweden has revealed the parts most sen- sitive to corrosion attack and the influence of changes in material or of the surface protective means on corrosion behaviors. In a stationary exposure at 6 Chinese and 3 Swedish sites the corrosivity of coupous and the effects of environmental parameters have been investigated. An extensive coupon exposure under buses displayed corrosion behaviors on free surfaces and in crevices, involving different construction materials, painting systems and temporary an- tirust agents. The corrosion mechanism of materials used for automobile, the affecting fac- tors, accelerated outdoor and indor corrosion test methods have also been researched.
