Формирование электродугового покрытия осуществляется с помощью аппарата для автоматической дуговой сварки ASAW-1250 с применением новой хромсодержащей порошковой проволоки на пластины из стали марки Ст3. Для исключения перемешивания наплавляемого металла со сталью подложки проводят многослойную наплавку. Режим наплавки рассчитывается и уточняется экспериментальным путем. Авторы исследовали состав и свойства поверхности электродугового покрытия после наплавки. В качестве заменителя аморфного углерода используется углеродфторсодержащий материал (пыль газоочистки алюминиевого производства). Наплавку осуществляли под флюсом, изготовленным из шлака производства силикомарганца с повышенным содержанием серы. Проведенный регрессионный анализ показывает влияние химического состава наплавленного слоя на его твердость и скорость износа. В работе получены математические модели исследуемых эксплуатационных характеристик электродугового покрытия. При увеличении содержания хрома, вольфрама, углерода и кремния повышаются твердость наплавленного металла и устойчивость его к абразивному износу. Результаты проведенных исследований позволяют выработать мероприятия для обеспечения требуемого уровня эксплуатационных характеристик электродугового покрытия и могут использоваться для составления прогноза твердости наплавленного слоя и его износостойкости при изменении химического состава металла, прогнозировать эксплуатационную стойкость прокатных валков, наплавленных проволоками типа ПП-Нп-35В9Х3СФ. Математические модели твердости наплавленного слоя и его износостойкости позволяют уточнить механизм упрочнения и формирования защитных свойств поверхностных слоев прокатных валков посредством электродуговых покрытий, наплавленных порошковыми проволоками.</p></abstract><trans-abstract xml:lang="en"><p>The paper considers research of quality of the electric arc coating obtained using flux-cored wire of the Fe – C – Si – Mn – Cr – W – V system with additives of carbon-fluorine-containing material and titanium. The formation of an electric arc coating was carried out using an automatic arc welding machine ASAW-1250 with a new chromium-containing flux-cored wire on plates made of St3 steel. To exclude mixing of the deposited metal with the substrate steel, multilayer surfacing was conducted. The surfacing mode was calculated and refined experimentally. The authors studied the composition and properties of the surface of the electric arc coating after surfacing. As a substitute for amorphous carbon they used a carbon-fluorine-containing material (dust of gas purification of aluminum production). Surfacing was carried out under a flux made from slag produced by silicomanganese with a high content of sulfur. A regression analysis of influence of the deposited layer’s chemical composition on its hardness and wear rate was carried out and mathematical models of the investigated performance characteristics of the electric arc coating were obtained. With an increase in the content of chromium, tungsten, carbon and silicon, hardness of the deposited metal and its resistance to abrasive wear increase. The results of the conducted research make it possible to develop measures ensuring the required level of performance characteristics of the electric arc coating and can be used to make a forecast of hardness of the deposited layer and its wear resistance when the chemical composition of the metal changes, to predict the operational resistance of rolling rolls deposited with wires of the PP-Np-35V9Kh3SF type. Mathematical models of hardness of the deposited layer and its wear resistance help to clarify the mechanism of hardening and formation of protective properties of the surface layers of rolling rolls by means of electric arc coatings deposited with flux-cored wires.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>порошковая проволока</kwd><kwd>электродуговое покрытие</kwd><kwd>многослойная наплавка</kwd><kwd>прокатные валки</kwd><kwd>твердость</kwd><kwd>скорость износа</kwd></kwd-group><kwd-group xml:lang="en"><kwd>flux-cored wire</kwd><kwd>electric arc coating</kwd><kwd>multilayer surfacing</kwd><kwd>rolling rolls</kwd><kwd>hardness</kwd><kwd>wear rate</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Metlitskii V.A.
