Název v původním jazyce

Tribological studies of high velocity oxy-fuel (HVOF) superalloy coatings

Popis výsledku v původním jazyce

High technology coatings layers on super alloys hardfaced by HVOF technology have very high wear resistance under extreme working conditions - adhesion, abrasion, corrosion cavitaion and vibrations. In the present work investigations have been carried out on wear of coating layers formed by HVOF under the conditions of dry friction on abrasive surface. The total number of studied samples is 12 powder compositions coated on nickel matrix (502P, 602P, 80M60) and tungsten matrix (6P50W, SX199, WC-12Co) at one and the same temperature of hardfacing. From each of the powders are obtained coatings without preliminary heating and with preliminary heating of the substrate in a chamber at 650oC. New and interesting results are presented on the wear characteristics and the loads plus the friction path. The influence of the preliminary heating on the wear rate and the relative wear resistance is tested and also the connection between abrasive wear and the hardface of the coatings.
