Abstract

The influence of the granulometric composition of ferroalloy components in the core of metal-cored wire (MCW) on the stability of the arc surfacing process, MCW melting characteristics, deposition quality, microstructural features, and properties of the multi­layer deposited metal was investigated. The MCW core contained an identical mixture of ferroalloy components designed to produce deposited metal of the 50Kh2N2MFS type. The difference between the studied CWs consisted in the granulometric composition of their core: 50…300 μm for the reference MCW and 50…100 μm for the experimental MCW. The feasibility of using ferroalloy compositions with a minimal particle size distribution (50…100 μm) in the MCW core for arc surfacing was demonstrated, as it improved MCW melting characteristics, process stability, and deposition quality, which in turn positively affected the structure and properties of the deposited metal.
