This paper describes the formation of a nanocomposite coating. It is a PTFE coating with the addition of TiAlV6 and WC (tungsten carbide) in size “nano”. Working with nanoparticles requires not only safety, but also preparation of nano size particles and their subsequent uniform deployment (the particles of this size affect electrostatic attractive forces and tend to aggregate). The first part describes preparation of particles by the process of mechanical grinding, the second part deals with the particle concentrations in relation to the total content of the solution that have been used. Further, the coating technology is described, since dispersed particles in solution during coating are susceptible to settling at the bottom of the coating vessel. The Scanning Electron Microscope (SEM) and Energy Dispersive Spectrometry (EDS) were used to evaluate the particle size and particle size distribution on the sample surface.
