Abstract

Results of the developed industrial technology of restoration of a surface corrosion-resistant staly are presented by method of laser building up. The comparative analysis of a microstructure of the built-up wearproof layer, an alloyage zone with material of a basis and diffusive zone at the different technological modes of building up is given. Influence of morphology of particles of additive powder on parametrical characteristics of the roller received by laser gas powder building up is investigated. The optimum modes of building up on a substrate from steel 12Cr18Ni10Ti are set. Tests for firmness against intercrystalline corrosion of the built-up powder compositions are executed by the AM method. Metalgraphic assessment of corrosion resistance is presented.
