Whatever the environmental temperature, coatings protect the surface of components and improve surface properties such as wear resistance, wear corrosion, and scratch resistance. Thin-film and tribological coatings Thin films can modify the superficial properties without affecting the basic bulk material characteristics. These functional coatings usually change both the hardness and toughness of the surface. They can also be tailored such that its durability, friction, and/or wear characteristics are dramatically improved. 2017-11-9 2000-8-3 · The fundamentals of coating tribology are presented in a generalised holistic approach to friction and wear mechanisms of coated surfaces in dry sliding contacts.

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.

Oils and additive packages, components size and surface finish, contact pressure and velocity bring new challenges for surface treatments and coatings. For decades, the performance of tribological coatings has been studied with the goal of developing practical surface treatments to enhance the friction and wear performance of mechanical components. 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.

Tribological dry coating is a system solution for mechanically stressed fastening elements and components, such as screws, nuts and washers. The coating is a non-electrolytically applied thin layer with integrated lubrication properties and additional corrosion protection.

2009-01-15 · One successful approach towards blending multiple lubricants and using their interaction with the environment to generate self-lubricating contact surfaces for a range of ambient conditions can be found in nanocomposite tribological coatings that employ a “chameleon” adaptive coating concept . Mustang has designed tribological coating equipment to impart hard wear resistant PVD coatings, such as DLC (Diamond-Like Carbon), Titanium Aluminum Nitride (TiAlN), Titanium Nitride (TiN) and Chromium Nitride or Chrome Nitride (CrN) coatings, for tools, medical instruments and implants, and automotive parts. the tribological properties of the coating. By using different doping elements such as W, Si and Cr it is possible to enhance and tailor certain properties, for instance increasing hardness, thermal stability and increasing affinity towards additives in lubricants. The presence of hydrogen in the DLC-coatings is due to the nature of the deposition Space tribology studies tribological systems that can operate under the extreme environmental conditions of outer space.
