Purpose: The main aim of this research was investigation of the gradient and multicomponent coatings structure deposited by cathode arc evaporation physical vapor deposition (CAE-PVD) on a SiAlON substrate. Design/methodology/approach: The structure of investigated coatings was characterized by scanning and transmission electron microscopy. Chemical composition was determined by energy dispersive spectroscopy (EDS) method. Investigation of surface roughness was done. Findings: The results of the investigations of microstructure, chemical compositions and surface morphology of gradient TiAIN and multicomponent AlSiCrN coatings deposited by PVD techniques are given in the paper. The linear analyses of chemical compositions on cross-sections of the investigated coatings are given. In the gradient coatings the chemical composition changes continuously at the cross-section. The result of the investigations of thin foils performed with use of transmission electron microscope and selected a diffraction are given also. Research limitations/implications: In future the examination will progress for mechanical properties, e.g. microhardness, adhesion strength and abrasive wear resistance as well as for the technological machining test. Originality/value: Future examinations will progress for mechanical properties, e.g. microhardness, adhesion strength and abrasive wear resistance as well as technological machining tests.
