New evaluation method for the characterization of coatings by electroerosive alloying

Abstract The running-in coatings were formed on the surface of tin bronze QSn10-1 by electroerosive alloying (EEA) with soft antifriction materials such as silver, copper, Babbitt B83 and graphene oxide (GO). mass transfer, roughness, coating thickness dry friction coefficient measured analyzed a precision electronic balance, three-dimensional optical profiler, metallographic microscope, scanning electron microscope (SEM), energy dispersive spectrometer (EDS) wear tester. An evaluation indicator system for characterization was constructed based six factors, including material price, time, alloying. Shannon entropy method used to calculate weight different indices, comprehensive performance proposed combining technique order preference similarity ideal solution (TOPSIS) multicriteria decision-making technique. TOPSIS model employed ranking
