Wear Resistance of TiN/TiCN and TiN/TiBN Multilayer Coatings Applied on Hot Work Tool Steel

Abstract:

T This paper examines the abrasive and erosive wear of duplex multilayer TiN/TiCN and TiN/TiBN coatings deposited on quenched and tempered hot work tool steel grade X37CrMoV5-1. The coatings were produced by duplex method composed of a plasma nitriding and pulsed direct current (DC) plasma-assisted chemical-vapor deposition (PACVD). Measurements of the thickness of the deposited coatings were determined by calotest. Adhesion of the layers were determined by the Rockwell-C indentation test and the microhardness profile in a diffusion zone beneath the surface was determined by Vickers method (HV 0.05). Tests of abrasive wear resistance were carried out using "Dry Sand-Rubber Wheel” method. Test of erosion resistance of the base material and of duplex layers was carried out by exposing test samples to impact erosion of fine sand particles and determining the loss of mass after 60 minutes of wear. Worn surface were analysed by stereomicroscopy. The results show increasing wear resistance of duplex multilayer coatings of TiN/TiCN and TiN/TiBN in relation to plasma nitrided and uncoated steel (in the quenched in tempered condition).
