摘要： A method of improving corrosion resistance of a cylinder cover including a port that is an intake port or an exhaust port. The cylinder cover is configured such that an annular cooling water passage is formed between an inner peripheral surface of the port and a valve seat ring when the valve seat ring is inserted in the port. The method includes forming a weld overlay layer on each of sealed regions of the inner peripheral surface of the port by laser metal deposition using a welding material made of a nickel-based alloy, a copper alloy, stainless steel, or a titanium alloy, the sealed regions being positioned at both sides of the cooling water passage, respectively.

摘要： A method of manufacturing a preliminary formed body includes an ironing step and a thickening step. In the ironing step, a predetermined range of a plate is formed into a tapered shape in such a manner that while rotating the plate, a transform target portion of the plate is locally heated by induction heating, and a processing tool is pressed against the transform target portion. In the thickening step, a peripheral portion that is a distal end of the tapered shape of the plate is expanded inward in such a manner that while rotating the plate, the peripheral portion is locally heated, and a forming roller is pressed against the peripheral portion to push the peripheral portion in a direction orthogonal to a thickness direction of the peripheral portion.

摘要： According to a spinning forming device, while a plate is rotated by a rotating shaft, a transform target portion of the plate is pressed by a processing tool and locally heated by a heater that performs induction heating. The heater includes a coil portion having a doubled circular-arc shape and is inclined by an inclining device relative to a direction from the rotating shaft toward the processing tool. A measuring unit measures distances each from the coil portion to an outer peripheral original portion of the plate at a plurality of measurement points distributed in a circumferential direction of the rotating shaft. A controller controls the inclining device based on a measurement result of the measuring unit such that an angle difference between the coil portion and the outer peripheral original portion becomes not more than a predetermined angle.

摘要： In a spinning forming method, a plate including a peripheral portion at which a ring-shaped projection is provided is used, the projection projecting in a thickness direction of the plate. Further, while rotating the plate, a transform target portion of the plate is locally heated, and a processing tool is pressed against the transform target portion to transform the plate. According to this configuration, a heat capacity of the peripheral portion of the plate can be increased. With this, when heating the vicinity of the peripheral portion of the plate, the peripheral portion can be prevented from becoming high in temperature. As a result, deformation of the peripheral portion of the plate can be suppressed.
