Surface treatment was conducted on aluminum alloy, ADC 12, by chemical tin plating, electroless nickel plating, electroless nickel plating (hardening), molybdenum disulfide coating on zinc phosphating, and hard anodizing; and on aluminum alloy, ADC 7, by hard anodizing. Then, the surfaces of above treated alloys were combined with steels, FC 15, S 15C, and S 15C (hardening), and subjected to wear tests to study the effects of surface treatment.The results obtained were summarized as follows:(1) Hard anodizing showed the most remarkable effect and electroless nickel plating (hardening) showed the second.(2) The treatment by hard anodizing was easier to conduct on ADC 7 than on ADC 12, and the wear resistance after treatment was higher in the former than in the latter. It was found that the hardness of the surface treated by electroless nickel plating was increased by heat treatment and its wear resistance was also improved. However, little effects were shown by soft and thin films such as treated by molybdenum disulfide coating and chemical tin plating.(3) When 3 kinds of steel materials, FC 15, S 15C, and S 15C (hardening), were combined with surface treated aluminum alloys, the tendency to toward wear resistance was nearly the same.
