Layer System and Component

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

This invention relates to a multilayer coating system designed for metallic components. The system consists of at least one adhesive (bonding) layer followed by multiple functional nanolayers. Each functional nanolayer includes a first nanolayer made of a hard metal nitride (such as MoN, CrN, TiN, etc.) and a second nanolayer composed of a metal (such as copper, silver, gold, etc.). The layer structure provides a wear-resistant and low-friction surface, especially when lubricants are present, significantly improving the durability and performance of metal machine parts.

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

• Wear-resistant coatings for machine parts such as cam followers, chain components, rolling bearings, control pistons, bushings, rocker arms, and sliding bearings.
• Coatings for automotive engine components where reduced friction and extended lifespan are important.
• Surface protection for industrial tools, dies, and cutting instruments.
• Application on moving mechanical assemblies in robotics and automation to reduce wear and friction.
• Enhanced coatings for high-performance sports equipment and aerospace components.

BenefitsContent extracted from patent full text and abstract with AI.

• Reduces friction between moving components, particularly effective when used with lubricants.
• Greatly improves wear resistance and extends service life of coated parts.
• Applicable at relatively low coating process temperatures (<350°C), enabling use on a broad range of metallic substrates without adversely affecting their properties.
• Enables tailored surface properties by selecting different combinations of metal nitrides and metals in nanolayers.
• Offers strong adhesion to metallic substrates due to the multi-step bonding layer design.
• Helps decrease maintenance needs by providing more durable and reliable machine components.
• Can be mass-produced using established PVD (Physical Vapour Deposition) methods for industrial scalability.

Patent Abstract

The invention relates to a layer system (1) comprising at least one adhesive layer (2a, 2b) and multiple functional layers (3, 4, 5, 6) which are arranged on the at least one adhesive layer (2a, 2b). Each functional layer (3, 4, 5, 6) comprises a first nanolayer (3a, 4a, 5a, 6a) made of a first metal nitride comprising a first metal component and a second nanolayer (3b, 4b, 5b, 6b) made of metal. Each functional layer (3, 4, 5, 6) has a thickness d ranging from 1 to 100 nm. The invention further relates to a component (100) comprising a metal substrate (10) and the layer system, which is at least partly arranged on the surface of the substrate (10).
