Abstract

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.
