Umcu wobheduukucoceka okuphezulu, izicubu ezintle, umxholo we-oxygen uphantsi kakhulu.Ine-conductivity elungileyo yombane, i-thermal conductivity, i-corrosion resistance and machining properties, kwaye inokudityaniswa kunye nebrazed.Amanyathelo okulawula umgangatho womphezulu womgca wobhedu obomvu: okokuqala, kufuneka siqinise ulawulo lwenkqubo yokuvelisa.Sebenzisa ibhrashi kunye namanzi ukucoca ukungcola okungaphezulu komcu wobhedu obomvu, kwaye usonge ngephepha lelinen phambi kokuqengqeleka ukunqanda ukuba umphezulu ungakrwelwa.Ukongezelela, indlela yokugoqa ioli yonke kufuneka yamkelwe, isixhobo sokususa i-oyile yelitye kufuneka sitshintshwe, kwaye isantya sokuqengqeleka kufuneka sincitshiswe, kwaye onke amanyathelo anokwenzeka kufuneka athathwe ukususa ukungcola okushiyekileyo kumphezulu.Kwangaxeshanye, abasebenzi bolawulo lwemveliso ukomeleza ulawulo lwemveliso, ukwandisa iinzame zokubeka iliso.
Okwesibini, ukukhuselwa kweegesi ze-inert ngexesha lokunyanga ukushisa kufuneka kuqiniswe.Ekubeni ubhedu luneempawu zeekhemikhali ezisebenzayo kakhulu, lunokusabela ngokukhawuleza kunye nezinto ezisebenza ngakumbi zegesi emoyeni xa ubushushu buphathwa kwiqondo lokushisa eliphezulu.Emva koko kuyimfuneko ukukhusela igesi ye-inert ngokufanelekileyo ukukhusela umcu wobhedu ukuba ube yi-oxidized.Xa kuyimfuneko, ukunyuka okufanelekileyo kwegesi engasebenziyo kukwayenye yeendlela ezinokwenzeka.
Kwakhona, ngokuqinisekileyo, kuyimfuneko ukuqinisa ukucocwa kwendawo, ukugcina umgangatho ophezulu wokugqiba.Kwinkqubo yokuqengqeleka kunye ne-annealing, umphezulu wobhedu uya kuvelisa ngokuqinisekileyo i-oxide, ngoko ke iindlela zokucoca eziyimfuneko ezifana ne-pickling, i-degreasing, i-passivation yokuqinisekisa ukuba ukuphunyezwa kokulungileyo.
Yomeleza ulawulo lokupakishwa kwemveliso egqityiweyo.Umcu wobhedu kufuneka womiswe emva kokucholwa.Indawo yomswakama iya kukhawulezisa ukubola kobhedu kwaye ichaphazele ukuchaneka kwemveliso egqityiweyo.Ngoko ke, ukwenzela ukuba kuqinisekiswe ukomiswa kwemveliso, kuyimfuneko ukuthatha indlela ephindwe kabini, ngelixa ukomisa umkhiqizo ogqityiweyo kangangoko kunokwenzeka, kodwa nokusebenza kwipakethe.Xa upakisha, ibhokisi yokupakisha inokuthi ifakwe ngephepha elinobungqina bomswakama, kwaye emva koko ihlanganiswe ngeengxowa zeplastiki, ukwenzela ukukhusela ngokufanelekileyo impembelelo yomswakama wangaphandle ngexesha lokuthutha.
