ピストン構造。 A protrusion with a machining center is provided on the piston head surface, while semi-finishing machining is performed on the outer peripheral surface of the piston where no ring groove is provided.
The protrusions and the outer peripheral surface of the piston are masked with paint, vinyl tape, etc., and in this state, a dispersion material having heat resistance, heat insulation, etc. is applied to the piston head surface. In a piston structure in dispersion plating of a piston in which the masking is removed and then ring groove machining and finish machining are performed on the outer circumferential surface of the piston using the machining center of the protrusion, the outer diameter of the lower part of the protrusion is defined as the outer diameter of the head. 1. A piston structure for dispersion plating of a piston, characterized in that the protrusion is formed relatively large, and the angle formed by the outer surface of the protrusion and the piston head surface is an obtuse angle.
