It is shown that under the conditions of hard abrasive wear, characteristic for parts of mining industry equipment, hardfacing with wear-resistant materials, in particular high-chromium cast iron, should be used. Such lining layers can be applied by electroslag hardfacing in a current-conducting mould of different cross-sections. Here, it is possible to apply both restorative and fabrication hardfacing. Features of hardfacing by each of these methods are shown. Industrial tests of deposited lining were performed in the case of components of jaw crusher SMD-11 and loader bucket. 7 Ref., 1 Tabl., 3 Fig.
