The automatic control system for spray fused coatings was developed. In this ysstem, V_x(=V_<max>・A) which is the traverse speed of a heat source, varies with the temperature of a just treated area, where V_<max> is the maximum speed of a heat source, and A is variable (named the temperature coefficient) calculated with a next equation. A={(t-T_L)/(T_H-T_L)}^n where t is the temperature of a just treated area, measured with a pyrometer, T_L and T_H are lower and higher limit temperatures of treatment set in advance, respectively, and n is a natural number. The system was designed for carrying out above control, and the performance of this system was confirmed. This automatic control system was applied actually to spray fused coatings of a self-fluxing Ni-base alloy. This system made it possible to spray and fuse the alloy satisfactorily, and the most suitable condition of treatment was calrified.
