Abstract
Invenţia se referă la galvanotehnică, şi anume la un procedeu de depunere acoperirilor din electrolit pe bază de crom trivalent.Procedeul de depunere a acoperirilor din electrolit pe bază de crom trivalent include depunerea acoperirii de crom dintr-un electrolit oxalat-sulfat, care conţine, g/L: Cr2(SO4)3·6H2O - 200, Na2C2O4 - 30, Na2SO4 - 80, la un PH de 0,8…1,2, temperatura electrolitului de 35…45°C, densitatea curentului catodic de 2,0…4,0 kA/m2, cu utilizarea unei surse de curent trifazat şi a unui dispozitiv inductiv-capacitiv, conectat consecutiv în circuitul de alimentare a băii galvanice, totodată dispozitivul este format din două blocuri - capacitiv şi inductiv, conectate paralel între ele, blocul inductiv având inductanţa în limitele 0,1…10,0 H, iar blocul capacitiv având capacitatea sumară în limitele 0,001…0,11 F.
