Purpose: The paper presents investigation results of functional properties of the sintered tool materials: high-speed steel matrix composites (HSSMC), cemented carbides, cermets and Al2O3 type oxide tool ceramics with (Ti,Al)N coating deposited in the cathodic arc evaporation CAE-PVD method and comparing them with the uncoated tool materials. Design/methodology/approach: Analysis of the mechanical and functional properties: surface roughness, microhardness tests, scratch tests, cutting tests. X-ray qualitative microanalysis of elements. Findings: Deposition of (Ti,Al)N coating onto high-speed steel matrix composites (HSSMC), cemented carbides, cermet and Al2O3 type oxide tool ceramics substrate causes increase of wear resistance as well as reduces the exceeding of steady stresses critical levels. It causes multiple (up to 800%) increase of tool life. As a result of metallographic observations it was stated that linear and uniform character of wear was achieved in case of all deposited samples. Practical implications: Employment of the hard coatings deposited onto sintered tool materials is reckoned as one of the most important achievements last year in the area of improvement of functional properties of cutting tools. Originality/value: Combination of substrates (especially coatings deposited on high-speed steel matrix composite) is unique and very interesting in respect of achieved functional properties.
