Abstract
Purpose of this work to probe the tribologichnu conduct of PEO glowed, synthesized on the easy alloys of AMg-6 and D16T in the clean mineral olive of I-20, with an appendix to it of the distilled water and water solution of glycerin at a contact from stalyami 45 and U8 . The tribological behavior of steels 45 and Y8 in pairs with PEO layers synthesized on light alloys AMg-6 and D16T in mineral oil I-20 with the application of distilled water and an aqueous solution of glycerin was investigated. They found a difference in the frictional behavior of plasma-electrolyte layers synthesized on aluminum alloys with increased magnesium content (AMg-6) and with an increased copper content (D16T) in contact with steel counterweights. In the case of contact between the plasma-electrolyte layers synthesized on the AMg-6 alloy with the steels under investigation, as a result of tribochemical reactions in the contact zone on the steel surface, a spinel-type oxide layer is synthesized with the general formula FeAl2O4, which protects them from wear by exposure to hydrogen, Loads not exceeding 4 MPa. In the case of contact between the plasma-electrolyte layers synthesized on the D16T alloy, oxygen-free wear of steel counter-bodies occurs and such a contact pair is operable to loads above 10 MPa with a low frictional heating temperature. Investigational tribological behavior of pair of dielectrics – an explorer (ceramics are a metal) glowed on the example of PEO, synthesized on the easy alloys of AMg and D16T in a contact with iron-carbon alloys – steel 45, U8.
