“…The COF reaches the similar values between 0.8 and 1.2 after run-in period for all of three investigated coatings independently from deposition conditions. This could be associated with the tribooxidation of Fe-W alloys at the early stages of fretting test, as it was noticed earlier [1]. Abrasive particles -iron oxides, may act as the third body particles that slide against the hard corundum counter body and result in high values of COF.…”

“…Therefore, for the alloys which undergo abrasive wear the resistance remains relatively unaffected with increasing the hardness and, in some cases, even decreased. For instance, the wear resistance of hard electrodeposited Fe-W alloys at dry friction is rather low, due to severe oxidation of the coating during fretting (tribooxidation) [1]. Formed oxides act as the third body, thus leading to the increase of coefficient of friction (COF) and larger wear volume, as compared to Co-W alloys evaluated at similar conditions.…”

“…At present, alloys of iron group metals, co-precipitated with tungsten, Co-W [7], which are promising for industrial use as thermo-wear-resistant magnetic-hard materials [8,9] with high microhardness, are of great interest. Such alloys can be an alternative to chromium coatings [10][11][12][13].…”

“…За фазовим складом бінарні покриви є твердими розчинами вольфраму в α-Co або α-Fe [3,23] [38,39], які досліджували молібден-вольфрамвмісні бінарні і тернарні системи. Отже застосований авторами підхід до формування вольфрамвмісних покривів з металами родини заліза у різних режимах електролізу є цілком виправданим і корисним.…”
