Abstract
1. Способ нанесения на металлические детали комплексного защитного покрытия, состоящего из множества микрослоев, включающий такие операции, как обезжиривание детали, размещение детали в вакуумной камере, откачку камеры до вакуума, предварительную очистку в среде инертного газа, ионную очистку/травление поверхности, осаждение слоев конденсацией с ионной бомбардировкой, охлаждение в вакууме, затем в среде инертного газа, отличающийся тем, что обезжиривание поверхности детали выполняют путем ультразвуковой мойки с ПАВ с последующей протиркой органическими растворителями, размещение детали выполняют в точке фокусирования потоков не менее чем двух вакуумных дуговых источников плазмы, при этом вакуумирование камеры производят до давление не выше 5·10мм рт.ст., а предварительную очистку выполняют в среде ионизированного инертного газа, кроме того ионную очистку/травление поверхности выполняют путем подачи на подложку сначала напряжения в диапазоне 200-500 В, затем повышают его плавно или ступенчато до 1-1,5 кВ, причем контролируют температуру изделия не выше 90% допустимой для обрабатываемого сплава детали, при этом при вращении детали осуществляют от трех до пяти колебаний температуры, приводящих к равномерному распределению температуры вглубь детали за счет чередования отключения и включения источника напряжения, чем обеспечивают равномерный прогрев и очистку детали, не превышая допустимой температуры, для нанесения микрослоев покрытия сплавы распыляют одновременно с одного или нескольких источников, выполняя вращение детали, причем для создания нитридных, оксидных и карбидных композиций используют газ в�1. The method of applying a complex protective coating consisting of many microlayers to metal parts, including operations such as degreasing the part, placing the part in a vacuum chamber, pumping the chamber to vacuum, preliminary cleaning in an inert gas medium, ion cleaning / etching of the surface, deposition of layers condensation with ion bombardment, cooling in vacuum, then in an inert gas medium, characterized in that the part is degreased by ultrasonic washing with a surfactant, followed by bright organic solvents, the placement of the part is carried out at the focusing point of the flows of at least two vacuum arc plasma sources, while the chamber is evacuated to a pressure of no higher than 5 · 10 mm Hg, and preliminary cleaning is carried out in an ionized inert gas, in addition to ion surface cleaning / etching is performed by first applying a voltage in the range of 200-500 V to the substrate, then increasing it smoothly or stepwise to 1-1.5 kV, and the product temperature is controlled not higher than 90% of acceptable for abatable alloy parts, while rotating parts carry out from three to five temperature fluctuations, leading to a uniform temperature distribution deep into the part due to the alternation of switching off and on the voltage source, which ensures uniform heating and cleaning of the part, not exceeding the permissible temperature, for applying microlayers alloys are sprayed simultaneously from one or several sources, rotating the part, and gas is used to create nitride, oxide and carbide compositions
