Wear resistance is where PVD really shines

Protect your tools, components and engine parts with a highly wear-resistant coating deposited by a specifically configured Hauzer machine

Wear-resistant coatings

Wear reduction is one of the most important aspects of PVD coatings. Wherever there is a tribological contact – where two surfaces interact – the surface will get worn away eventually through abrasive, adhesive, fretting or erosion wear or surface fatigue. Each of these wear mechanisms needs to be countered with a specific set of coating properties for the best result. Hauzer machines can be configured for a wide range of wear-resistant PVD coatings, including metal nitrides, carbon-based coatings and metal oxides.

Why a Hauzer solution

As experts in PVD coatings, we have designed the Hauzer coating machines with the flexibility to provide the best wear-resistant coating for your application.

Hauzer machines can be configured with a wide range of deposition technologies and can deposit a multitude of wear-resistant PVD coatings
Our process engineering knowledge supports complex joint development projects to reach an optimal solution for your specific application
Metal nitride, metal oxide and diamond-like carbon (DLC) coatings each have their specific advantages
Hauzer has a proven track record as market leader supplying coating machines to OEMs and coating service providers

A coating family specifically important for wear resistance is DLC. Within DLC coatings, it is possible to distinguish several variations, all of which Hauzer machines can provide.

Metal-DLC: strong against rolling contact fatigue, so it is used to provide a longer lifetime for bearings
PACVD-DLC: a general coating, often used to protect tribological contact areas in automotive and industrial components
Doped DLC: a coating that is tuned to decrease the coefficient of friction or increase compatibility with specific lubricating oils
Sputter DLC: a coating with increased hardness, combining low friction and improved wear resistance
Hydrogen-free tetrahedral amorphous carbon (ta-C) coating: DLC coating with improved temperature resistance and compatibility with low-viscosity oils; increasingly popular in automotive because of increased engine temperatures

Applications for wear resistance

Because wear resistance is such a fundamental property of PVD coatings, these coatings are popular for a wide range of markets and applications.

For instance, in the automotive industry, engine components that are coated include fuel injection components, piston rings and pins, and valve train components.
The industrial components market is broad and varied, and items that need coating range from hydraulic components to bearings and needles.
The aerospace industry also applies wear-resistant coatings on a variety of items, from engine parts such as turbine vanes to the actuators for wing flaps, flight control components and even the guiding pins for assembling, disassembling and reassembling engines during maintenance.
The tool industry can generally be split into cutting tools and forming tools. Wear-resistant PVD coatings are used on cutting tools to maintain their performance. On forming tools, a coating improves the tool’s integrity. In both markets, PVD coatings help extend the useful life of the tools.

PVD coatings are also used in other sectors, such as heavy-duty industry and general industrial applications.

The Timken Company about their wear-resistant coating

“Once we apply wear-resistant coating on our products, we rarely hear any complaints from our customers. Our DLC coatings are now widely accepted as the solution to many challenging applications that were difficult to meet before,”

Tribo active coatings interact with lubrication

The conclusion of research, by facility of Surface Engineering Institute (IOT) at RWTH Aachen, was that under tribological loads, i.e. contact pressure and temperature, MoS2 and WS2 were formed as a result of the reaction of the coating with the lubricant additives. This resulted in reduced friction.

High productivity equipment in the automotive industry

“Conventional PVD coatings for piston rings are mostly CrN coatings. However, we developed a hydrogenfree carbon coating, ta-C and a-C, that offers many functional benefits, such as an average 20% reduced friction loss, very low wear and superior scuff resistance.”

Hard, low-friction coatings for tool applications

For tools to form and cut non-ferrous metals and plastics, the best coating is hard, with a low coefficient of friction, reducing built-up edge and keeping the cutting edge sharp. Cutting tests show that one of the diamond-like carbon (DLC) coatings, the tetrahedral amorphous carbon (ta-C) coating, applied with HiPIMS is an excellent solution for this application and many others.

Excellent Adhesion and Cohesion

New test results show that ta-C coating applied by HiPIMS, smoother than ta-C applied traditionally, has excellent cavitation wear resistance and adhesion. Ruud Jacobs, Process Manager Tribological Coatings, says: “From a technical perspective, we consider the HiPIMS carbon coating to be one of the best – if not the best – performing coatings available.”
