    Abstract: A nozzle (4) for use in a cold spray technique has a passageway (18) for spraying a powder material, the passageway (18) having a converging section (100) and a diverging section (102), and at least the diverging section (102) being formed from polybenzimidazole. In one embodiment of the nozzle, the converging section (100) is also formed from polybenzimidazole.

    Abstract: 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).

    Abstract: A process for restoring a worn edge (106) of a component used in an engine is provided. The process comprises providing a component with a worn edge (106), and depositing at least one layer of powder metal material onto the worn edge (106) using a non-oxidizing carrier gas so that the powder metal material plastically deforms without melting and bonds to the worn edge (106) upon impact with the worn edge (106).

    Abstract: A method for depositing a metallic material onto a substrate (10) comprises the steps of placing the substrate in a vacuum chamber (52), inserting a spray gun nozzle (20) into a port (50) of the vacuum chamber (52), and depositing a powdered metallic material onto a surface of the substrate (10) without melting the powdered metal material. The depositing step comprises accelerating particles of the powdered metal materials within the vacuum chamber (52) to a velocity so that upon impact the particles plastically deform and bond to a surface of the substrate (10).
