Abstract

In this work, the compositions of the charge of experimental flux-cored wires for the technology of electric arc metallization are developed. As modifying additives selected powders of niobium Nb content in the charge flux-cored wire is 0,1%, 0,3%, 1% and 5% by weight.X-ray spectral analysis and scanning scanning electron microscopy studied the composition and structure of wear-resistant coatings.

Tribological studies have shown that the wear of the samples is reduced by an order of magnitude, starting with the addition of 0.3% niobium. When the content of niobium powder wire 1% and 5% wear resistance remains high, but the mass loss of samples and counterbody are balanced, due to the grinding of the microstructure and increased uniformity of the micromechanical properties.
