    摘要： A film formation method in which a cylinder head rough material (3) having an annular valve seat part (16c), which is a film-deposited portion, and a nozzle (23d) of a cold spray device (2) are moved relative to each other along a film formation trajectory (T) in which a film formation starting point (P 2 ) and a film formation finishing point (P 5 ) of the film-deposited portion overlap to form an overlapping portion, and a coating film is formed on the film-deposited portion while a raw material powder is continuously sprayed from the nozzle, wherein the film is formed such that at the film formation starting point of the overlapping portion, an inclination angle ( θ ) of an end part of the coating film relative to a surface of the film-deposited portion is 45° or less.

    摘要： A method for processing a cylinder block is disclosed, wherein a protrusion protruding toward a crankcase is provided at a crankcase-side edge of a cylinder bore and a sprayed coating is formed on an inner surface of the cylinder bore and an inner surface of the protrusion continuous with the inner surface of the cylinder bore. After forming the sprayed coating, at least part of the protrusion is removed together with the sprayed coating formed on the inner surface of the protrusion. Accordingly, even in the case of removing the edge portion of the cylinder bore on the crankcase side, a sufficient margin to be removed can be ensured while a reduction in size of the cylinder block is achieved.

    摘要： The present invention comprises at least a pedestal (45) on which a cylinder head (12) is placed in a predetermined orientation, a base plate (26) disposed in a position away from the cylinder head, a rotation means (29) that causes the base plate to rotate about a rotational axis (C), a spray gun (23) mounted on the base plate so that a spray direction is directed toward the rotational axis, a high-pressure pipe (21b) which guides a working gas to the spray gun, and a rotating joint (21k) provided to a base end of the high-pressure pipe, the high-pressure pipe being arranged along the rotational axis.

    摘要： A film forming method for forming a coating film on a workpiece (3) having a plurality of film-deposited portions (16c) which are not continuous with each other by moving a nozzle (23d) of a cold spray device (2) relative to each other along a continuous movement trajectory (MT) including trajectories (T) of the plurality of film-deposited portions and a connecting trajectory (CT) linking the trajectories of the plurality of film-deposited portions while continuously spraying a raw material powder from the nozzle and the raw material powder is sprayed by cold spraying to form a coating film on each of the film-deposited portions, wherein a turnback point (TPi) where a relative speed between the workpiece and the nozzle decreases in the movement trajectory is set on the connecting trajectory.
