Evaluation of the Adhesion Strength of Metal Spray Coating System in Steel using High-frequency Arc Metal Spray Method

고주파 아크 금속용사기를 이용한 금속용사 코팅계의 부착강도 평가

The purpose of this study is to analyze the adhesion strength of metal spray coating system in steel using high-frequency arc metal spray method. For the purpose the experimental factor such as surface roughness was selected at 3 levels. As a result of experiment, it appeared that high-frequency arc metal spray method had higher adhesion strength than existing metal spray method. Especially, Al-Mg showed the highest adhesion strength than other metals. In case of surface roughness, the higher roughness steel has, the higher adhesion strength appeared.
