Abstract

The invention relates to an apparatus, systems and methods involving a cold spray coating. A cold spray coating system (100) comprising, a cold spray coating gun (102) having a nozzle member (214) operative to emit a stream of gas and granules of a coating material from a nozzle opening (218) defined by the nozzle member (214) such that the granules of the coating material impact and bond with a first region of a substrate (406), and a heat source member (202) operative heat the first region of the substrate (406).

Description

technical field [0001] Cold spray systems and methods are used to apply various types of coatings to substrate objects. For example, a mechanical component made of steel may be coated with a layer of protective material to prevent corrosion of the mechanical component. Background technique [0002] Cold spray methods use spray guns that receive high-pressure gases such as helium, nitrogen, and air, for example, and coating materials such as metals, refractory metals, alloys, and composite materials in powder form, for example. The powder particles are directed under high pressure into the air stream in the spray gun and ejected from the nozzle. The gas flow velocity may be supersonic. Particles are accelerated to supersonic velocities in the gas flow. [0003] The powder impacts the substrate at high velocity. The kinetic energy of the powder deforms and flattens the powder particles upon impact with the substrate. Flattening promotes metallurgical bonding, mechanical b...
