Abstract
Several kinds of experiments have been carried out on acid electroless plating,alkaline electroless plating and multi-component plating.The properties of three catings have been tested in experiment.In order to improve hardness of coating,the chemical coatings have been heat-treated at different temperature.The test results show that the property of corrosion resistance of multi-component Ni-Cu-P plating-coating is the best,acidic electroless plating-coating takes the second place and alkaline electroless plating-coating is the worst.The hardness of the coatings was increased to the maximal value between 400 ℃and 500 ℃,multi-component electroless plating-coating reaches the highest hardness and lower frictional coefficient,so it has very good wear resistance.
