Heat Resisting Plasma Spray Coating on a Cylinder Head of Aluminum Alloy 871207

A new method was developed to help determine the conditions that would create adhesion strength of heat-resisting coatings formed in plasma spraying. This method is a combination of an experiment design that uses a Latin square and multiple regression analysis. Since it allows the direct analysis of experimental data, conditions can be determined in one third of the number of tests required by conventional experimental methods. The multiple regression equation gained through this study is also effective in comparing the heat resistance of the heat-resisting coating.
