However, the performance of DLC-coated parts depends on the compatibility and interaction between the coating and lubricant additives. To obtain high-

Known parameters that affect coating performance include contact pressure, rolling velocity, sliding velocity, lubricant film thickness, and surface roughness. In the bulk form, polymers may show lower dimensional stability because of high thermal expansion as the local temperature and the frictional contacts in the bulk polymers may be higher due to low dissipation of heat as compared to the thin polymer coatings. Moreover, the tribological response of the coatings depends upon many other factors such as the properties of the substrate and adhesion to the substrate, which in turn depends upon the cleanliness and the pre-treatment procedures. Tribological performance of the developed hybrid nanocomposite coating was evaluated using a 6.3 mm diameter stainless steel (440C) ball as the counterface in a ball-on-disk configuration. Tests were carried out at different normal loads (7 N, 9 N, 12 N, and 15 N) and a constant sliding velocity of 0.1 m/s. The present study addresses the influence of the gradient microstructure of nanocrystalline TiAlSiN coatings on their tribological behaviour.

2015-6-2 · The tribological performance of a Bi+WS2 composite coating has been evaluated and compared with the performance of a STD Bi coating such as those currently used as overlay coatings in bearing applications in automotive market. The novel composite coatings exhibits

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. If the cause of failure is wear, an extension of tool life could be achieved by the application of PVD coatings. Materials and Coatings These advanced alloys and composites represent a major advancement for the field of bearings and related mechanisms.
