Project description:In the last decade, hard coatings based on nitrides or carbonitrides of transition metals play significant role in increasing the lifetime of the cutting and forming tools, but also in specific products of mobile devices. The main requirement for this type of material is high hardness and abrasion resistance. However, in the case of dynamic leading and frequent alternation of heat cycles, the adhesion of the coating to the substrate is the decisive factor. The object is just focused to this area with the main aim to find and optimize physical processes to enhance the adhesion ability of selected types of coatings and create a mathematical model that could describe the physical processes involved. The specific goal is to verify the influence of the initial state of the substrate surface prior to the coatings deposition both in terms of structural,thermal and deformation characteristics of the coatingsubstrate phase interface. Different methods for cleaning of substrates, surface exposition and deposition technologies will be utilized for these tasks. The techniques of plasma, magnetron and ion sputtering as well as cathodic arc evaporation will be mainly used. The experimental methods such as electron microscopy, X-ray diffraction analysis. Auger electron spectroscopy and optical emission spectroscopy as well as a special ion beam/ matter interaction based techniques (RBS, PIXE) will be utilized for the study and explanation of processes that could occur at the coating/ substrate phase interface. The method of FEM will be used for the clarification of effects of both internal and residual stresses to the coating/ substrate interface character. The output will be a comprehensive analysis of the influence of individual parameters of used processes on increasing of interface adhesion and drafting the proposals for their applications in the preparation of hard coatings with enhanced exploitative properties.
