Coating is an engineering process in which by covering the surface with suitable materials, it is possible to increase the durability of parts, machines and equipment. With the development of nanotechnology, the process of coating parts was developed using this technology, which increases the life and efficiency of industrial parts and tools. Hard and durable Nano-coatings are a group of coatings that have dimensions of 1 to 100 nanometers in one of their components and also have special and unique properties compared to conventional and traditional coatings. In Nano-coating technology, due to the Nano-nature of coatings, different and unique properties will be created on the surface of the part.
