摘要:This paper evaluates the wear characteristics of hardfacing coatings. Regenerative hardfacing coatings were applied with the TIG (Tungsten Inert Gas) method. The solid welding wires were used to obtain the coatings markedas: EL-500 HB, EL-650 HB, and EL-3348. The tribological analysis of samples was conducted at room temperature. The wear rate was evaluated with a THT 1000 Anton Parr ball-on-disc tribotester, in accordance with theASTM G-133 standard. The counterbody (static partner) consisted of balls with the diameter of 6 mm made ofAl2O3. The test was performed with the sliding speed of the friction pair 0.4 m/s, track radius 10 mm, normal load20 N, acquisition rate 10 Hz and sliding distance 2000 m. During the test, the friction coefcient and wear ratewere recorded. The multi-criteria assessment of the construction materials discussed, while taking into accountfve criteria, showed that EL-3348 HB is the best material. Computer applications were used for multi-criteria assessment and statistical processing of data.
