Yini okufanele ngiyenze uma i-vacuum annealing yesithando somlilo i-oxidized kakhulu?
Yini okufanele ngiyenze uma i- isithando somlilo i-annealing i-oxidized kakhulu?
Esithandweni se-vacuum annealing, umucu wethusi ufakwe i-oxidized, okubonisa ukuthi isithando somlilo kuyavuza.
1. Hlola ukuthi i-vacuum esebenzayo yepompo ye-vacuum ijwayelekile yini. Sebenzisa i-vacuum gauge ukuze uhlole i-vacuum endaweni yokungena yepompo ye-vacuum ukuze ubone ukuthi ingafinyelela yini endaweni yokugcina yokungena yepompo. Uma kungenjalo, shintsha uwoyela, noma ulungise, futhi ungalokothi ushintshe iphampu.
2. Sebenzisa isikhethi esivuzayo ukuze ucoshe ukuvuza esithandweni somlilo. Uma ungekho umtshina ovuzayo (umtshina ovuzayo ubiza kakhulu), sebenzisa i-acetone (utshwala bemboni) ukuze ucoshe ukuvuza, izinga elijwayelekile lokuthola ukuvuza ngu-0.2Pa/h, akufanele kube khona inkinga.
