Abstract
A first metal powder is supplied to a substrate to form a beginning part of a clad layer. After the beginning part is formed, the second metal powder is supplied to the substrate. A concentration of at least one of Si, Ni, Mo, and Al in the first metal powder is lower than a concentration thereof in the second metal powder.
Claims13
A method of producing a clad layer comprising:
- supplying metal powder that is copper-based metal powder to a surface of a substrate made of aluminum or aluminum alloy, emitting a laser beam to the metal powder, and melting the metal powder, the metal powder including a first metal powder and a second metal powder;
- and
- moving a supply position of the metal powder and an emission position of the laser beam in a predetermined direction along the surface of the substrate and forming the clad layer on the surface of the substrate in the predetermined direction,
- wherein the first metal powder is supplied from a first feeder to the substrate to form a beginning part of the clad layer, and after the beginning part is formed, the second metal powder is supplied from a second feeder to the substrate, and a concentration of at least one of Si, Ni, Mo, and Al in the first metal powder is lower than a concentration of the at least one of Si, Ni, Mo, and Al in the second metal powder so that a powder alloy components of the first metal powder are different from powder alloy components of the second metal powder, and wherein the second feeder is different from the first feeder.
