Abstract
Inventia se refera la procedeele electrice si termochimice de prelucrare a pieselor din otel si poate fi folosita în industria constructiilor de masini si în constructia aparatelor pentru marirea rezistentei la coroziune a pieselor masinilor, sculelor si utilajului tehnologic.Procedeul, conform inventiei, consta în aceea ca se efectueaza alierea prin scântei electrice a suprafetei piesei din otel strat cu strat cu durata impulsurilor de 10…2500 µs si frecventa de 1500…25 Hz corespunzator, cu obtinerea unei acoperiri, apoi se efectueaza tratamentul termochimic anodic al acoperirii obtinute timp de 1…5 min într-un electrolit ce contine compusi anorganici ai azotului cu un adaos de 0,5…15 g/l de tanin la tensiunea dintre electrozi de 150…220 V, densitatea curentului de 1…20 A/cm2 si temperatura anodului de 600…900°C cu calirea-oxidarea ulterioara în electrolit. Dupa aceasta piesa se mentine timp de 3…5 ore în acid ortofosforic concentrat si/sau într-o solutie de nitrit de sodiu cu concentratia de 30…150 g/l la temperatura de 70…100°C, apoi piesa se spala, se usuca si porii acoperirii se umplu electrolitic cu material izolant.
