European emission standards are becoming more and more important in China for both western OEMs as well as Chinese ones. As a result of that trend, Hauzer Techno Coating, a supplier of leading technology for functional coatings in auto engines, has seen its market grow significantly in China.
Physical Vapour Deposition (PVD) and Plasma Assisted Chemical Vapour Deposition (PACVD) coatings are used for several purposes. In automotive engines these coatings are mainly applied on components to achieve wear reduction and reduce the friction between components. The end result is a longer engine life and considerable fuel savings combined with lower CO2 emissions.
One reason that component manufacturers use PVD coatings is because of reduced wear. Many vehicle and engine manufacturers demand a service life of one million kilometres without incurring significant wear. A Chromium Nitride (CrN) coating, for example, on the piston rings, can increase the engine life significantly.
Another advantage of tribological PVD and PACVD coatings is a reduction of friction. In a passenger car, up to 15% of the energy input is consumed by friction losses. By applying tribological coatings on valve train components, friction loss can be reduced by 50%, resulting in 1%t less CO2 emissions output. An example of a coating used for these purposes is Diamond Like Carbon (DLC) coating. For DLC coatings produced by PACVD, no expensive target materials are necessary, which makes it a very cost-effective solution.
Many component producers and job coaters all over the world use Hauzer’s CrN, me-DLC and DLC coatings to improve the performance of their components. Diesel fuel injection parts, piston rings, gears, journal bearings, piston pins and valve train components are just a few of the applications where PVD and PACVD coatings are applied full scale.
Hauzer Techno Coating will serve the Chinese market for tool and tribological coatings even better now that the company has opened a competence centre in Shanghai. In this competence centre Chinese customers are able to receive local customer support and training by experienced Chinese engineers. In the second half of 2009, the competence centre will be fully operational and pilot production, process qualification and coating development for customers are possible. Component manufacturers, tool manufacturers and job coaters will profit.
Hauzer is a worldwide expert in the field of automotive tribological coatings. The Dutch company supplies coating equipment to most leading component manufacturers and job coating centres all over the world. Hauzer is well-known for sharing its technological knowhow with its customers. Hauzer’s hi-tech coating systems are robust and flexible and they are always provided with leading edge technology for the best possible coating result. Hauzer has competence centres in China, the Netherlands and Japan.
