Description
Известны иирофосфорнокислые электролигы никелировани , содержащие сернокислый никель , пирофосфорнокислый калий и аммоний хлористый.There are known nickel-plating phosphors of nickel plating containing nickel sulphate, potassium pyrophosphate and ammonium chloride.
Предлагаемый электролит отличаетс от известиых тем, что, с целью повышени рассеивающейс способности электролита и получени мелкокристаллических беспористых покрытий , в электролит ввод т буру при следующе .м соотношении компонентов (г/л):The proposed electrolyte differs from the lime in that, in order to increase the dissipative capacity of the electrolyte and to obtain fine crystalline non-porous coatings, a drill is introduced into the electrolyte at the following ratio of components (g / l):
никель сернокислый40- 60nickel sulphate40- 60
калий пирофосфорнокислый 160-200 аммоний хлористый3- 5potassium pyrophosphate 160-200 ammonium chloride3- 5

Процесс ведут при рН 8,5-9,5 плотности тока 1 -1,5 а/дм и температуре 20-25°С.The process is carried out at a pH of 8.5-9.5 current density of 1 -1.5 a / dm and a temperature of 20-25 ° C.
Катодный выход никел по току составл ет 65-75%; анодный выход по току lOOVo.The cathode nickel current output is 65-75%; anode current output lOOVo.
Осадк никел мелкокристаллические, светлые , блест щие, при толщине 2-3 мк ирактически беснористые.The precipitation of nickel is fine-crystalline, light, brilliant, with a thickness of 2-3 microns and almost unorhous.
Рассеивающа способность электролита, рассчитанна но методу Кудр вцева и Никифоровой , составл ет 28-Зф/о (рассеивающа способность сернокислого электролита 3%). The scattering capacity of the electrolyte, calculated using the Kudr vtsev and Nikiforova method, is 28-Zf / o (the scattering power of the sulfuric acid electrolyte is 3%).
Твердость Hardness
осадков никел составл ет 500 кг/мм-.Nickel precipitation is 500 kg / mm.
При повышении температуры электролига до 50°С выход металла по току повышаетс до 80-86;Vo.When the temperature of the electrolyte rises to 50 ° C, the metal's current yield rises to 80-86; Vo.
Внутренние напр жени в осадках никел , полученных по предложенному способу, прп толщине покрыти 5-6 мк и плотности тока 1 -1,5 а/дм в 3-5 раз меньше, чем в сернокислом электролнте при тех же услови х.The internal stresses in the precipitations of nickel, obtained by the proposed method, are 5–6 microns thick and the current density is 1–1.5 a / dm 3–5 times less than in the sulphate electrolyte under the same conditions.
