Method for Coating a Component and Coated Component

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a method for coating a component by first roughening its surface using a laser, which creates crater-shaped indentations. The roughened surface is then coated through a cold gas spraying technique. This combination improves the adhesion between the coating and the component, resulting in a robust, high-quality coated part. The patent also covers components produced by this method.

Use CasesContent extracted from patent full text and abstract with AI.

• Protective coatings on machine parts to increase wear and corrosion resistance
• Repairing damaged industrial components by recoating with the original material
• Applying specialized surface layers (e.g., anti-friction, thermal barrier) to turbine blades, engine parts, or aerospace structures
• Coating medical instruments for enhanced durability and biocompatibility
• Improvement of electronic or electrical component surfaces to increase reliability

BenefitsContent extracted from patent full text and abstract with AI.

• Provides significantly stronger bonding between the coating and the substrate compared to conventional methods (such as sandblasting before coating)
• Allows thicker and more reliable coating layers, extending component life
• Reduces risk of thermal or chemical damage to the base material during preparation and coating
• Enables precise, repeatable surface preparation using a laser for better quality control
• Applicable to a broad range of materials, including metals, ceramics, polymers, and composites
• Can be performed under protective gas atmospheres to further prevent oxidation and contamination
• Offers potential for both new part manufacturing and refurbishment of worn or damaged parts

Patent Abstract

The object of the invention is to further develop the coating of a component (4). The object of the invention is achieved by a method for coating a component (6), in which the surface to be coated of the component (8) is roughened by a laser and the roughened surface is coated by cold gas spraying. The invention also relates to a component (8) produced by the method that is coated with a layer (5).
