Physical-chemical-metallurgical characteristics of contact layers in tribo-mechanical systems depend on the operating conditions and the conditions under which the work surfaces were created. That is the reason the influence of the processing procedures and regime, used in the contact surfaces formation, on development of the wear process of contact elements, is being considered ever more. To determine the influence of the hard-facing technology on characteristics of the gears\u2019 working surfaces, the experimental investigations were performed on samples hard-faced on the steel for cementation, by varying the filler metals (FM) and the hard-facing regimes. The samples tested were hard-faced by five \u201chard\u201d and three \u201csoft\u201d filler metals. Experimental investigations included measuring the hard-faced layers\u2019 hardness and determination of their microstructure, as well as the wear resistance in the laboratory conditions, on tribometer and on a specially designed device for tests in the real operating conditions of gears. The wear intensity was monitored by the wear trace\u2019s width in the laboratory conditions and by the share of the teeth surfaces affected by the destructive pitting in the operating conditions. The results obtained were compared to results of the base metal (BM) tests, which provided the certain conclusions on which filler metal and which welding procedure are the optimal ones for regeneration of the worn teeth surfaces.<\/jats:p>","DOI":"10.3390\/ma15217795","type":"journal-article","created":{"date-parts":[[2022,11,7]],"date-time":"2022-11-07T03:02:22Z","timestamp":1667790142000},"page":"7795","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Analysis of Filler Metals Influence on Quality of Hard-Faced Surfaces of Gears Based on Tests in Experimental and Operating Conditions"],"prefix":"10.3390","volume":"15","author":[{"given":"Svetislav","family":"Markovi\u0107","sequence":"first","affiliation":[{"name":"Faculty of Technical Sciences \u010ca\u010dak, University of Kragujevac, 32000 \u010ca\u010dak, Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vuki\u0107","family":"Lazi\u0107","sequence":"additional","affiliation":[{"name":"Faculty of Engineering, University of Kragujevac, 34000 Kragujevac, Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0326-0898","authenticated-orcid":false,"given":"Du\u0161an","family":"Arsi\u0107","sequence":"additional","affiliation":[{"name":"Faculty of Engineering, University of Kragujevac, 34000 Kragujevac, Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3042-8916","authenticated-orcid":false,"given":"Ru\u017eica R.","family":"Nikoli\u0107","sequence":"additional","affiliation":[{"name":"Research Centre, University of \u017dilina, 010 26 \u017dilina, Slovakia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Djordje","family":"Ivkovi\u0107","sequence":"additional","affiliation":[{"name":"Faculty of Engineering, University of Kragujevac, 34000 Kragujevac, Serbia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5694-4284","authenticated-orcid":false,"given":"Robert","family":"Ulewicz","sequence":"additional","affiliation":[{"name":"Department of Production Engineering and Safety, University of Technology, 42201 Czestochowa, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9928-2332","authenticated-orcid":false,"given":"Otakar","family":"Bokuvka","sequence":"additional","affiliation":[{"name":"Faculty of Mechanical Engineering, University of \u017dilina, 010 26 \u017dilina, Slovakia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,4]]},"reference":[{"key":"ref_1","unstructured":"Lazi\u0107, V., and Arsi\u0107, D.
