Изобретение относитс  к химико-тер- гаческой обработке металлов и сплавов.This invention relates to the chemical-thermal treatment of metals and alloys.

Известна среда дл  диффузионного меднени  в порошках стальных изделий при пропускании водорода, содержаща , вес. %:A known medium for diffusive copper plating in powders of steel products by passing hydrogen, containing, by weight. %:

Медь5ОCopper5O

Окись алюмини  50 1 .Aluminum oxide 50 1.

Недостатком известной среды  вл етс  низка  скорость насыщени  изделий из алюмини  и его сплавов.A disadvantage of the known medium is the low saturation rate of products from aluminum and its alloys.

Цепью изобретени   вл етс  интенсификаци  диффузионного меднени  алюмини  и его сплавов.The chain of the invention is the intensification of the diffusion copper plating of aluminum and its alloys.

Это достигаетс  тем, что предложенна  среда дополнительно содержит окись медиThis is achieved by the fact that the proposed medium additionally contains copper oxide.

и хлористый аммоний при следующем соотношении компонентов, вес.%:and ammonium chloride in the following ratio of components, wt.%:

Медь10-20Copper10-20

Окись меди10-20Copper oxide 10-20

Хлористый аммоний1-3Ammonium Chloride1-3

Окись алюмини  ОстальноеAlumina Rest

В таблице приведены данные о глубине сло  на образцах из алюмини  марки А7 после меднени  при температуре 5ОО С в течение 40О час.The table shows data on the depth of the layer on samples of aluminum grade A7 after copper plating at a temperature of 5OO C for 40O hour.

Поверхностна  твердость и износостойкость алюмини  после диффузионного меднени  увеличиваетс  в 3-4 раза.The surface hardness and wear resistance of aluminum after diffusion copper coating increases by 3-4 times.
