DUPLEX TREATMENT OF NICKEL ALLOY APPLIED TO LOW-CARBON STEEL BASE

摘要

We studied the structure, morphology and elementary composition of Ni-based coatings (PG-10N-01 and PGAN-33) from 60 to 110 μm thick applied by plasma detonation followed by fusing with a pulsed plasma jet and an electron beam. It is shown that that duplex treatment produces solid and plastic intermetallide compounds (FeCr, Fe{sub}7Mo{sub}6, CrB) in the coatings and smoothes the surface relief. It has been established that microhardness grows 4.5 times; wear reduces from 9 to 90 times, resistance to corrosion in the sulfuric acid solution increases as well.
