| Abstract: | Manganese phosphating process for piston made of aluminium was investigated. Surface uniformity and wear-resistance as quantitive parameters, the effects of major components, additives, temperature and time on the properties of the phosphating film were investigated. The optimum phosphating process was obtained. The results show that the process is characterized by stable capability and easy maintenance. Phosphating film is gray-black, bright and uniform with good corrosion resistance, wear resistance and thermal resistance. The analysis of phosphating mechanism indicates that the phosphaing film is made of aluminium phosphate and manganese phosphate. |
