Coated articles and methods and systems for coating the articles are described herein. The methods and systems described herein include, but are not limited to, steps for actively or passively controlling the temperature during the coating process, steps for providing intimate contact between the substrate and the support holding the substrate in order to maximize energy transfer, and/or steps for preparing gradient coatings. Methods for depositing high molecular weight polymeric coatings, end-capped polymer coatings, coatings covalently bonded to the substrate or one another, metallic coatings, and/or multilayer coatings are also disclosed. Deposition of coatings can be accelerated and/or improved by applying an electrical potential and/or through the use of inert gases.

The invention relates to a coating system for a component of a turbomachine, which includes at least two different base powders. Each of the at least two different base powders has an individual predetermined distribution within the coating system. Further, each of the at least two different base powders is responsible for a specific property of the coating system.

A thermal spray apparatus to apply coatings to external and internal surfaces in restricted areas is provided. The apparatus includes: a combustion chamber having a primary passage for combustion of fuel received through a fuel input line with oxygen or air received through an oxidizing gas input line; a divergence section located downstream of the combustion chamber; an elbow housing located downstream of the divergence section. A nozzle housing retaining a nozzle having an injection zone and a nozzle throat; a convergence section retained between the elbow housing and the nozzle housing; a feedstock injector for the injection of feedstock material into the injection zone of said nozzle; and a plurality of passageways extending through the combustion chamber, the divergence section, the elbow housing, and the convergence section for passing a coolant therethrough.

A thermal spray cabin comprising a table to hold a part to be coated and a robot with a robot body and an arm, a spray gun mounted on the arm of the robot, a ventilation system comprising an air inlet and a suction hood designed to create a gas flow with a main stream from the air inlet to the suction hood thereby passing the table in an operating state of the thermal spray cabin. The air inlet, the table, the robot and the suction hood are arranged in such a way, that the robot body is positioned outside the main stream of the gas flow in the operating state.

A nozzle for a thermal spray gun and a method of thermal spraying are disclosed. The nozzle has a combustion chamber within which fuel is burned to produce a stream of combustion gases. The streams of heated gases exit through a pair of linear exhausts which are located on either side of an aerospike. The streams converge outside the nozzle and powdered coating material is introduced into the converging streams immediately downstream of the aerospike. The coating material is heated and accelerated before impacting on a substrate to be coated.

A nozzle for a thermal spray gun and a method of thermal spraying are disclosed. The nozzle has a combustion chamber within which fuel is burned to produce a stream of combustion gases. The stream of heated gases exits through an annular exhaust which is located around an aerospike. The stream converges outside the nozzle and powdered coating material is introduced into the converging stream immediately downstream of the aerospike. The coating material is heated and accelerated before impacting on a substrate to be coated.
