Abstract
Corrosion resistance of metal of 30Kh20MN and 30Kh22MN types, produced by submerged arc surfacing using different techniques and technologies of surfacing was investigated. The feasibility of increasing the corrosion resistance of the deposited metal by proper selection of the surfacing technology was found. The best results on corrosion resistance were obtained in a pulsed surfacing using flux-cored wire at its feeding with 0.5 Hz pulse. The results of investigations can be used in restoration of worn-out parts and manufacture of the new ones of hydraulic equipment. 6 Ref., 2 Tables, 5 Figures.
