EFFECT OF CRYSTALLINE-STRUCTURE OF REACTION-PRODUCT ON SELENIUM-PLATING RATE OF COPPER

The effect of the state of the reaction product on the rate of formati on of new phase layers is discussed in an example of the selenium-plat ing of copper. Investigations were conducted on single crystals with d ifferent degrees of perfection (conditional splitting was carried out in accordance with the size of the blocks and angles of disorientation ) and polycrystals. It was established that at T < 673-degrees-K, an i ncrease in the degree of perfection of the crystalline structure of th e reaction product gives rise to a reduction in the selenium-plating r ate of copper. When T > 673-degrees-K, the rate of selenium plating is independent of the degree of perfection of the crystals of the reacti on product.
