A Study on the Optimum Conditions in Stainless Steel Arc Spraying

스테인레스강 아이크 용사에 있어서의 최적 용사조건에 관한 연구

In this study, the experiments were earried out for the purpose of the clarifying the optimum metal arc spraying conditions, such as spraying distance, wire feed speed, arc current, etc, by using the stainless steel wire ER 308L. Main results obtained are as follows: 1. Optimum spraying distance is closely related to the equilibrium temperature of base material in back surface. 2. The size fused metal particles is increased according to the temperature of fused metal. 3. The maximum adhesion strength of coatings is obtained under the optimum spraying conditions of which the temperature of fundamental is maximum.
