Thanks to the coating of metallic surfaces subjected to friction, REWITEC Nanocoating offers ideal protection for wind turbine transmission and bearings, even under the most extreme environmental conditions.
The metal-silicate layer created improves tribological properties, reduces pitting and grey staining, increases the scuffing load capacity, reduces the need for replacement components, extends operational lifecycles and, in consequence, increases system profitability.
Nanocoating uses for wind turbines.
Abrasion and wear in engines, gearboxes, bearings and other mechanical systems are caused by friction between metallic surfaces. Traditionally, the application of lubricants attempts to create a separating film to prevent direct contact between metal surfaces. However, as conventional lubricants are unable to provide long-term protection for metallic surfaces under all operating conditions, REWITEC GmbH developed a product that improves the superficial structure of metallic components subjected to friction on an enduring basis.
The REWITEC coating technology is not based on modifications to the lubricating film, but instead relies on the modification of the superficial structure of components subjected to friction and the formation of a new and extremely smooth silicate layer. This silicate layer possesses excellent emergency running properties in the case of total oil loss and significantly reduces the lubricant and fuel consumption of internal combustion engines. In many cases, even previously damaged metallic surfaces can be reconstructed and sealed.
The coating concentrate is simply added to the original lubricant and is transported by it to the points at which friction occurs. The silicates occupy and fill the smallest holes and cracks in the metallic surfaces and combine with the metal to create and extremely wear-resistant metal-silicate layer. Metal-silicate surfaces created in this manner have not only a much lower friction coefficient, but also enable much better and faster creation of lubricant films.
