Opis:: The paper deals with the problems of nanoparticles and nanomaterials applied in technical practice. The research on the use of nanoparticles has at present a great development. Their potential has a large of use. Particles of nano-size, i.e. below 100 nm exhibit other properties than larger particles and because this area is being explored in all possible sectors. The effect of adding these particles at different mechanical properties in coatings on various surfaces neat (separated on a band saw, milling work, ground roughness 800 and 80 polished) dependent on quality prepared nanoparticles by different conditions of milling. One of the possibilities for an extension of the duty cycle of tyre production molds is applying a protective coating. Due to the functionality of the desktop is needed a very thin coating layer. A suitable type of coating is thus a PTFE coating, which prolongs the service life of hundreds of percent. Better possibility how to improve an extension of the duty cycle is the addition of the coating titanium dioxide particles into the PTFE medium. This is the way how to create nanocomposite directly on the mold surface.
