This article deals with a possibility of another extension longer lasting addition of coatings of titanium dioxide. The research based on the use of nanoparticles has development at present. Potential of added nanoparticles has large use. Particles of Nano size, i.e. below 100 nm exhibit other properties than larger particles and because of that this area is being explored in all possible sectors. This article deals specifically with the possibility of extending the lifetime of working surface molds made of aluminium alloy injection rubber mixtures used in automotive. Lifetime is longer lasting with PFTE coatings. Subsequently, it shows the effect of adding these particles at different mechanical properties in coatings on various surfaces (separated on a band saw, milling work, ground roughness 800 and 80 polished). In these cases roughness and hardness are evaluated. In the last part particles, their even distribution and size are identified. This is evaluated by electron microscopy.
