Abstract
1. Способ нанесения покрытия на внутреннюю поверхность трубы, включающий коаксиальное размещение в вакуумной камере электродов, в качестве одного из которых используют обрабатываемую трубу, а в качестве второго - мишень, длина которой не меньше длины обрабатываемой поверхности, инициирование вакуумного электрического разряда между электродами путем создания разности потенциалов и воздействие плазмы разряда на наружную поверхность мишени при наложении на разрядную зону скрещенного с электрическим магнитного поля, отличающийся тем, что магнитное поле создают пропусканием электрического тока через мишень или через мишень и проводник, расположенный в полости, выполненной в мишени. ! 2. Способ по п.1, отличающийся тем, что магнитное поле создают пропусканием переменного электрического тока.1. The method of coating the inner surface of the pipe, including coaxial placement of electrodes in a vacuum chamber, one of which uses the processed pipe, and the second target, the length of which is not less than the length of the processed surface, initiating a vacuum electric discharge between the electrodes by creating potential differences and the effect of the discharge plasma on the outer surface of the target when a magnetic field crossed with an electric field is applied to the discharge zone, characterized in that a magnetic field is created by passing an electric current through the target or through the target and the conductor located in the cavity made in the target. ! 2. The method according to claim 1, characterized in that the magnetic field is created by passing an alternating electric current.
