چکیده انگلیسی
The aim of this work is to present the effect of synergy interaction hybrid surface treatment of tool ceramics using methods of CVD chemical coating deposition and selective laser texturing on the structure and properties of obtained hybrid surface layer. Comprehensive research results in scanning electron microscopy (SEM), morphology with atomic force microscope (AFM) as well as chemical composition of produced coatings with EDS scattered energy spectrometer are presented. Exploitative properties, including adhesion with the "scratch test" method, wear resistance using the "pin on disc" method, roughness were also tested. As a result of the research, it was found that the creation of a hybrid layer of the CVD coating/laser texturing on the tool ceramics contributes to the improvement of the exploitative properties of the tested material. The honeycomb texture (in the micro-scale) created as a result of the selective laser treatment with the nanoripples (in nano scale) causes a decrease in the friction coefficient and the width and depth of the wear. Nanoripples LIPSS are a barrier to the damage propagation in the coating after exceeding the critical load confirmed during the adhesion tests.
