The quality, structure, chemical composition and mechanical properties of bimetallic materials prepared by argon- arc surfacing of copper alloys MNZhKT 5-1-0.2-0.2, Sv-MN18, Sv-MNZhMtsTK 40-1-1-0.3-0.1, MMts40, BrAZhNMts 8.5-4-5-1.5 and Monel NMZhMts 28-2.5-1.5 on high-strength low-alloy steel AB3 are investigated. It is shown that during surfacing copper alloys on steel, high-quality bimetal is provided without defects in the form of cracks, significant porosity, unmelted areas, or exfoliation.
