LASER SPRAYING METHOD AND DEVICE

摘要

PURPOSE:To enable the laminating of a high m.p. material on a low m.p. material by passing a material to be sprayed through laser beams so radiated that the beams pass by a substrate and generating plasma for a chemical reaction at the intersection of the beams and the material. CONSTITUTION:Laser beams 51 for melting a material M to be sprayed is radiated so that the beams pass by a substrate 20. The material M is fed to the substrate 20 from a prescribed angular direction so that the material M passes through the beams 51. Plasma is generated with a plasma generator 60 at the intersection Pc of the beams 51 and the material M to cause a chemical reaction and a sprayed film of a product is formed on the substrate 20.
