Исследование процесса легирования наплавленных покрытий, полученных из поверхностно-легированной проволоки бором с дополнительно нанесенным гальваническим покрытием хрома и меди

Abstract

Researches on distribution of chrome and copper in the fused coating received from the superficial alloyed wire by boron with in additionally applied electroplated coating of chrome and copper were executed. The structure of the fused coating consists of dendrites on which borders the boride eutectic is located. It is established that the content of chrome in dendrites is 1,51,6 times less than in the borid; distribution of copper on structure is uniformed. Coefficients of digestion of chrome and copper at an argon-arc welding from a wire electrode with electroplated coating are established. The assimilation coefficient for chrome is equal to 0,9-1,0; for copper 0,6-0,75.

Выполнены исследования по распределению хрома и меди в наплавленном покрытии, полученном из поверхностно-легированной проволоки бором с дополнительно нанесенным гальваническим покрытием хрома и меди. Структура наплавленного покрытия состоит из дендритов, по границам которых расположена боридная эвтектика. Установлено, что содержание хрома в дендритах в 1,5-1,6 раза меньше, чем в боридах; распределение меди по структуре равномерное. Установлены коэффициенты усвоения хрома и меди при аргонно-дуговой наплавке из проволочного электрода с гальваническим покрытием. Коэффициент усвоения для хрома равен 0,9-1,0; для меди 0,6-0,75.
