Copper based powder, surface coated copper based powder, mixed powder of these, laminated laminate, method for producing the same, and various metal parts

摘要

An object of the present inventionEspecially 1.2 μ When lamination is performed by irradiating a laser beam having a wavelength ofCopper powderIt is possible to form a powder layer with a small porosity and high densitySuitable for forming a layered material consisting of a high-density copper based materialCopper powderSurface coated copper based powder, mixed powder of these, laminated laminate and its manufacturing methodAndVarious metal parts formed using a laminated material are provided.Copper based powder of the present invention 1.2 μ Laser beam with wavelength of less than m is used as a material to be laminated and the average particle size is 50 μ The 50% particle diameter (D50) is 50 to 50 of the cumulative particle size distribution obtained by measuring the volume μ M and 10% particle diameter μ M.
