Abstract
A process for depositing a powder metal onto a substrate is performed by providing a substrate, depositing at least one layer of powder metal onto a surface of the substrate using a non-oxidizing carrier gas so that the powder metal plastically deforms without melting and bonds to a surface upon impact with the surface, 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.

A process for depositing a powder metal onto a substrate comprising the steps of:
- providing a substrate;
- depositing at least one layer of powder metal onto a surface of said substrate using a non-oxidizing carrier gas so that said powder metal plastically deforms without melting and bonds to a surface upon impact with said surface;
- and
- subjecting said at least one powder metal deposited layer to a treatment to improve density and/or raise a temperature of said at least one powder metal deposited layer.
An apparatus for depositing a powder metal onto a substrate comprising:
- means for depositing at least one layer of powder metal onto a surface of said substrate using a non-oxidizing carrier gas so that said powder metal plastically deforms without melting and bonds to a surface upon impact with said surface;
- and
- means for subjecting said at least one powder metal deposited layer to a treatment to improve density and/or raise a temperature of said at least one powder metal deposited layer.
