Laser enhancements of cold sprayed deposits

摘要

A process for depositing a powder metal onto a substrate (10) is performed by providing a substrate (10), depositing at least one layer of powder metal onto a surface (24) of the substrate (10) using a non-oxidizing carrier gas so that the powder metal plastically deforms without melting and bonds to a surface (24) upon impact with the surface (24), and subjecting the at least one powder metal deposited layer to a treatment to improve density and/or raise a temperature of the at least one powder metal deposited layer. In a preferred embodiment of the present invention, the treatment to improve density and/or raise a temperature of the at least one powder metal deposited layer is a laser treatment effected by a laser (60).
