Purpose: The paper presents investigation results of structure and properties of steel matrix composites (SMC) uncoated and coated with hard (Ti,Al)N gradient coatings with use of physical vapour deposition process. Design/methodology/approach: Powder Metallurgy, PVD, TEM, SEM, XRD, GDOES, Microhardness tests, Scratch test. Findings: Depositing of gradient (Ti,Al)N coatings onto SMC materials meets the requirements connected with hybrid technology of production, joining powder metallurgy and physical vapour deposition techniques, in area of producing modern composite gradient tool materials. Sintered steel matrix composites reinforced with hard carbide phases and deposited with gradient PVD coatings can be widely employed in industry for tools, especially for machining and plastic forming processes. Practical implications: Tool materials used especially for tools employed especially in machining and plastic forming processes. Originality/value: Modern methods of powders’ forming application make possible to achieve gradient structure of tool, which is very advantageous in respect of mechanical properties. Employed compositions of technologies joining powder metallurgy and physical vapour deposition techniques give the possibility to achieve high properties characteristic of cemented carbides with the high ductility characteristic of steels.
