摘要： The nozzle for cold spray (25) used in a cold spray apparatus (2) is configured to include a tubular nozzle main body (252) and a cooling jacket (253) that surrounds the nozzle main body (252) to form a flow path (25e) for refrigerant (R) between the nozzle main body (252) and the cooling jacket (253). The cooling jacket (253) is provided with a seal retaining portion (253c) that retains an O-ring (253b) for the flow path (25e). The seal retaining portion (253c) and the nozzle main body (252) are joined in a socket-and-spigot joint fashion.

摘要： In a method for manufacturing a cylinder block provided with cylinder bores, the cylinder block is held by a clamp device, stress is generated in the cylinder block by a holding force of the clamp device to duplicate deformations of the cylinder bores after assembling hearing caps thereon, boring is carried out with the cylinder bores deformed in a condition where the stress is generated, and a thermally sprayed coating is formed, after the boring, on each inner surfaces of the cylinder bores deformed in the condition where the stress is generated. According to the method for manufacturing a cylinder block, superior cylindricity, after assembling the bearing caps, of the cylinder bores on each of which the thermally sprayed coating is formed can be brought, and workability degradation of finishing works (honing) for each inner surface of the cylinder bores (thermally sprayed coatings) can be restricted.

摘要： A sprayed coating forming method of forming a sprayed coating includes pre-heating a cylinder block defining a plurality of cylinders, supplying air into an enclosure that houses the cylinder block, inserting a spray gun sequentially into cylinder bores formed in the cylinder block while discharging the air at least from one side of the cylinder block, and spraying droplets of a molten metal onto an inner surface of each of the cylinder bores. The spraying includes spraying one of the cylinder bores first, then next spraying another of the cylinder bores that has at least one cylinder disposed between the another of the cylinder bores and the one of the cylinder bores sprayed first. The air flows around the cylinder block and also flows inside the cylinder bores.

摘要： In a method for a finishing work of a spray-coated surface, an inner surface of a cylindrical hollow member is roughened by forming a helical groove thereon. A thermal spray coating is formed on the inner surface that is roughened, and a finishing work is carried out by cutting the thermal spray coating along a helix of the groove by use of a cutting tool. According to the method for a finishing work, a finishing work of a thermal spray coating with non-uniform hardness can be carried out efficiently.
