Izvleček
The tribological properties of the multi-layer PVD and CVD coatings deposited onto the Si3N4 nitride tool ceramics are compared in the paper in relation to the fundamental mechanical properties like hardness, adhesion. The inserts made from Si3N4 were multilayer coated in the PVD process with the TiN + multiTiAlSiN + TiN, TiN + TiAlSiN + TiN, and TiN + TiAlSiN + AlSiTiN coatings and in the CVD process with the TiC, Ti(C, N), Al2O3 and TiN. Additional investigations were carried out to compare coatings obtained in this way on inserts from various manufacturers offering the nitride tool ceramics with the CVD coatings based on the Al2O3 and TiN layers. Basing on the tribological test made with the "pin-on-disk" method in respect to the hardness and adhesion investigations the correlation was revealed between these two properties. Machining tests results and roughness tests results for the machined grey cast iron surface are also presented. The CVD coatings demonstrate high abrasion resistance in comparison with the PVD ones, whose adhesion to the nitride ceramics is low.
