The Scientific and Educational Center «Perspective Technologies and Materials» of the Sevastopol State University has developed a technology for obtaining a universal additive to motor oils based on nanodispersed tungsten disulfide from metalworking waste. Currently, nanoparticles are increasingly being used as lubricant additives. Due to their small size (2-100 nm), they easily penetrate into the friction zone, fill microroughnesses and form protective films, and also have a self-healing effect on worn surfaces. At the same time, tungsten disulfide has the best anti-wear and lubricating properties.
then we sinter them with sulfur particles. This is a production waste, so the cost of an additive to oils will be significantly lower. So far, we have received trial micrograms in the laboratory and are looking for approaches to make scaling. We sent proposals for cooperation to Tomsk, St. Petersburg and Moscow, — quotes the press service of the director of the center Vladimir Gavrish.
There are no major producers of tungsten sulfide in Russia. In world markets, it is inferior to the United States and China. The creation of a domestic technology for the production of highly effective additives will allow Russian industrial consumers to reduce their dependence on foreign suppliers and develop new innovative oils, meet the needs of the domestic market and compete for external ones.
