Ukwelashwa okushisaUngenye yezinqubo ezibalulekile ezibalulekile ekuvuseleleni inqubo yokufa yokufa, edlala indima enqumayo empilweni. Ngokuya ngezidingo eziqondileUkuqinisekisa ubuchwepheshe, ubuchwepheshe bokwelashwa okushisa kwenzelwe ukwenza amandla (bunzima) buka-midlalo wokubumba kahle ngokuqina komzimba, ubulukhuni bomzimba wobumba kanye nomfaniswano, okusanhlamvu kuhamba phambili, akunamfaniswano, awukho i-oxifation futhi Ukuqunjelwa, kunciphise ukucindezelwa okusele kanye ne-deformation, okungathuthukisa impilo nokuqina kwesikhunta. Ukusetshenziswa kobuchwepheshe obusha bokushiswa kokushisa kungathinta amandla ezinto ezibonakalayo futhi kuthuthukise kakhulu impilo yokubumba ngezindleko ezincane. Isibonelo, nge-carbon ephezuluKubanda Kufa Kufa, ukwamukela ukushisa okuphansi kokuthola ama-lat martensite angathuthukisa ubulukhuni, ukunciphisa ukuguquguquka kwesikhunta nokucisha ukuqhekeka, futhi ngenxa yalokho ukuthuthukisa impilo. Ukwelashwa okushisa kwe-vacuum kunezinzuzo ze-noxidation, ukuhumusha, ukuqubuka, ukushisa okufanayo kanye noshintsho oluncane, oluzuzisa ukuthuthukisa impilo yabafe.

Umphumela wokwelashwa komhlaba wokuqinisa ingaphezulu kwesikhunta nokukhulisa impilo yokubumba akusimangali nje, kodwa futhi nezindleko eziphansi. Isetshenzisiwe futhi inezinhlelo zokusebenza ezingaba khona zendawo yokubumba yokuqiniswa kwendlela yokwelashwa ebanzi inodoti (idubule i-pening, ukukhishwa kwesigaba sokuqina, ukuqina kokuqina komhlaba kanye nokuqiniswa kwe-ion Ubuchwepheshe bokuguqulwa kwe-Vapor nobuchwepheshe obufana nobuchwepheshe be-membrane onjenge-Chemical Vapor Design, kanye ne-Electrochemical Design (Electroplating) Technology kanye nengubo yokufafaza okushisayo.
