PURPOSE:To remelt easily, securely and automatically a melt-sprayed film, by measuring continuously the remolten surface temp. of the melt-sprayed film and controlling the moving speed of a heat source or an object to be treated so that the measured value is kept between preset max. and min. heating temps. CONSTITUTION:A melt-sprayed film on an object 1 to be treated is heated and remelted by a heat source 3, and the temp. on the remolten surface 5 thereof is continuously measured with a thermometer 6. The measured value of the thermometer 6 is inputted into a computer incorporated in a controller 7. The max. heating temp. and min, heating temp. on the remolten surface are beforehand set in the computer according to the characteristics of the melt-spraying material for forming the melt-sprayed film and therefore the controller 7 controls the moving speed of a moving device 4 for the heat source or the base of the object 1 so that the measured value is kept within the range of the set values. |
