PTFE Based Multilayer Micro-Coatings for Aluminum AlMg3 Forms Used in Tire Production

The basic prerequisite for obtaining the coating of good quality is production a layer without occurrence surface defects. A possible solution to defects on functional form application polytetrafluoroethylene (PTFE)-based coating. helps reduce roughness and “smooth” like pores micro-shrinkage. For this reason, new type methodology were prepared achieve more cycles between individual cleaning processes during tire. subject study was analysis surface-applied micro-coatings, including chemical composition by using energy-dispersive X-ray (EDX) microstructure in area coatings. Detailed microstructural characterization Alfipas 7818 Alfiflon 39 its imaging structures studied atomic force microscopy. To examine coatings, metallographic specimens cross-sections (by means mold) examined light electron This multilayer micro-coating with thickness 20–25 μm has been found prevent contamination tire extend 200–400% process cleanings. finding actually tested tires environment large manufacturing company.
