High-temperature oxidation influence on composition and structure of aluminide coating on ion implanted surface of nickel alloy

Abstract

The paper discusses the influence of hightemperature oxidation on composition and structure of vacuum-plasma coating VSDP-11 deposited on TsNK7P alloy substrate implanted with ytterbium ions. The elements redistribution in the coating after exposition at 850 oC was studied and the interdependence between the elements redistribution and the life cycle of the protective coating was established. The ion implantation benefits resulting in the increase of the alloy surface heat resistance were shown for the additional nickel alloy surface treatment for the purpose of vacuum-plasma coating deposition.
