ABSTRACT
This paper evaluates the wear characteristics of hardfacing coatings. Regenerative hardfacing coatings were applied with the method TIG (Tungsten Inert Gas) The solid welding wires were used to obtain the coatings marked as: EL-500 HB, EL-650 HB, EL-3348 of Most. Tribological analysis of samples was conducted at room temperature. The wear rate was evaluated with a ball-on-disc tribotester THT 1000 Anton Parr, in accordance to ASTM G-133 norm. The counterbody (static partner) consisted of balls with the diameter of 6 mm made of Al2O3. The test was performed with the sliding speed of the friction pair 0,4 m/s, track radius 10 mm, normal load 20 N, acquisition rate 10 Hz and sliding distance 2000 m. During the test, one registered the friction coefficient and wear rate. The multi-criteria assessment of the construction materials discussed, while taking into account five criteria, showed that the best material is EL-3348 HB. For multi-criteria assessment and statistical processing of data computer applications were used.
