Способ относится к химико-термической обработке и может быть использован при сварке, механической обработке труднообрабатываемых сплавов с подогревом. При упрочнении поверхности короткой электрической дугой дисковыми электродами происходят частые замыкания междугового пространства каплями жидкого металла, что нарушает стабильность горения дуги и качество поверхности. Стабилизация дуги осуществляется за счет механического разрыва перемычек короткого замыкания при вращении дискового электрода. Увеличение окружной скорости до 15. . .20 м/с позволяет уменьшить интенсивность и длительность импульсов. При частоте вращения 5 - 60 с-1 достигается высокая стабильность и устойчивость горения дуги.The method relates to chemical-heat treatment and can be used when welding, machining difficult-to-work alloys with heating. When the surface is hardened with a short electric arc with disk electrodes, frequent short circuits of the intergapular space with drops of liquid metal occur, which violates the stability of the arc and the surface quality. The arc is stabilized by a mechanical break of the short-circuit jumpers during the rotation of the disk electrode. Increase the peripheral speed to 15.. .20 m / s allows to reduce the intensity and duration of the pulses. With a frequency of rotation of 5 - 60 s - 1 , a high stability and stability of the arc is achieved.
