Improvement of technologies for increasing the resource of metal parts

popup.description2

 The report presents the results of research on the influence of chemical composition and technological parameters of arc surfacing on the properties of bimetallic layers of high-alloy wear-resistant cast iron. The dependencies of hardness, crack formation and porosity of the deposited metal on the content of silicon and aluminum in surfacing materials were established. Recommendations on the composition of flux-cored strips and charge for arc surfacing were developed. The proposed technological solutions are aimed at improving defect-free deposition and increasing the durability of metallic structures operating under abrasive and hydro-abrasive wear conditions.
