AB The article focuses on technological procedures of coating of metal molds made from Al-Si alloys, espe-cially used for making tyres. The idea is to create coating on aluminium based metal molds in order to reach a higher number of production cycles between individual cleaning operations in tyre making tech-nology. The experiment was based on a preparation of experimental samples, which were coated with a teflon based product with the addition of nanoparticles (eg. TiO2), in other words, particles as large as tens of nanometres, which were mixed into the teflon solution in a particular concentration. After creat-ing the coating, the experimental samples were put under a thermal load in various thermal modes. Fu-thermore, roughness, coating resistance, and changes after the thermal load were subjects of the study.
