Tribological performance of different coating-lubricant systems Xin HE 01/2012—06/2012. Acknowledgements I would like to acknowledge and thank the following persons

Carbon-based coatings are used in many applications, particularly in sliding contacts to reduce friction and wear. To improve the tribological properties, these coatings are usually alloyed with metals; W is one of the most used since it helps improve the tribological performance at high temperatures.

A thin alumina layer was deposited on top of the a-C:H:Si coating to improve the tribological performance at high temperatures. The a-C:H:Si coating and alumina layer were prepared using plasma-activated chemical vapour deposition and atomic layer deposition Being deposited on various engineering materials, functional tribological coatings allow resolving contradictions between bulk and surface properties of engineering components. Precise control of wear and frictional properties is crucial for applied engineering applications. Tribological properties of nanostructural DLC/WC coatings were measured with a high temperature pin-on-disc CSM Tribometer in the range from room temperature (RT) up to 500 °C.

Tribological coatings

Coatings were electroplated using commercially available products—zinc acidic bath and a nanoparticle carrying plating additive. Electrochemical measurements were carried out to compare the anticorrosion performance of coatings. An investigation into the influence of Tribological dry coatings The surface systems are used to optimize the coefficient of friction and improve protection against corrosion. They consist of compositions such as organic solid lubricants and fluoropolymers and can be designed according your requirements. In cold forging processes the high tribological and mechanical loads often lead to early tool failure.

Surface coating of tribological applications is associated with deposition temperatures ranging from room temperature to over 1000°C, see Fig. 2. The coating thicknesses range from microns to several millimetres. Typically, the atomistic methods produce the thinnest coatings. The use of hard thin coatings on softer substrate materials is very popular in many tribological applications. The hard coating can provide good wear protection and, with a suitable choice of material and surface layer design, the friction can also be low, against an appropriate counterface.

Whatever the environmental temperature, coatings protect the surface of components and improve surface properties such as wear resistance, wear corrosion, and scratch resistance.

The very low friction that was expected for H-DLC, however, was not observed and the tungsten disulfide-based coating dominated the tribological behavior. It is concluded that the best coating system for foil bearing applications consists of placing the soft solid lubricant coating on the foil pad and the hard, wear-resistant coating on the disk.
