APPARATUS AND METHOD FOR COLD SPRAYING AND COATING PROCESSING

摘要

A nozzle element for applying powder material to a substrate is provided. The powdered material is applied from the nozzle element onto the substrate generating a coating of the powder material defined by a first film thickness and a first particle size of the powder material. A deformation nozzle element is provided for spraying shot toward the coating of powder material disposed upon the substrate deforming particles of the powder material disposed in the coating forming a second particle size being smaller than the first particle size and deforming the coating to define a second film thickness being less than the first film thickness.

1. A method of applying a coating to a substrate, comprising the steps of:
providing a nozzle element for applying powder material to a substrate; spraying the powdered material from said nozzle element onto the substrate thereby generating a coating of the powder material defined by a first film thickness and a first particle size of the powder material; providing a deformation nozzle element for spraying; spraying shot from the deformation nozzle element toward the coating of powder material disposed upon the substrate thereby deforming particles of the powder material disposed in the coating forming a second particle size being smaller than the first particle size and deforming the coating to define a second film thickness being less than the first film thickness.
