Abstract

Inventia se refera la un procedeu de acoperire chimica cu un aliaj nichel fosfor într-o solutie de sulfat de nichel, folosind ca reducator hipofosfitul de sodiu. Se obtine o acoperire cu urmatoarele proprietati: culoare alb-argintie, cu nuante galbui aderenta corespunzatoare rezistenta la coroziune corespunzatoare duritatea acoperirii de 400...600 niu HV poate fi marita la 800....1000 niu HV prin tratament termic o ora la 400 degree C. Aceste acoperiri au rol protector, protector decorativ în functie de grosime înlocuitor al cromarii dure productia pieselor strîns tolerate.
