Vpliv procesnih parametrov na kvaliteto galvanske obdelave

Bergelj, Filip (author), Ručigaj, Aleš (mentor)

Elektrokemijsko galvaniziranje je na mikroskopskem nivoju sestavljeno iz štirih procesov: prenos naboja, masni transport, kemijske reakcije in kristalizacija. Pri galvaniziranju je število vhodnih parametrov veliko, najbolj pomembni izmed njih pa so tok, napetost, čas in koncentracije snovi v raztopini. V tej diplomski nalogi je preučen vpliv koncentracije cinka, natrijevega hidroksida in niklja na lastnosti galvanskega sloja cink-niklja, eksperimentalno določena pa je tudi učinkovitost procesa. Ti vplivi so preučeni s pomočjo eksperimentalnega dela v laboratoriju in statistično obdelavo teh podatkov ter podatkov iz proizvodnje.

Abstract

Electrochemical galvanization is composed of four processes at the microscopic level: charge transfer, mass transport, chemical reactions and crystallization. There are many input galvanization parameters, with the most important being electric current, voltage, time and concentrations of substances in the solution. This thesis studies the effects of the concentrations of zinc, sodium hydroxide and nickel on the properties of the galvanic layer of zinc-nickel. The efficiency of the galvanization process is also determined. These effects are studied with the help of experimental work in the laboratory and with statistical analysis of data gained from the laboratory and production.
