Indlela yenqubo yesithando sokushisa esiphansi se-vacuum tempering

1) Izinto ezisetshenziswayo zifakwe ibhokisi lokwelapha i-cryogenic eligadwa ngokuqhubekayo yikhompyutha futhi lingakwazi ukulungisa ngokuzenzakalelayo inani le-nitrogen ewuketshezi futhi linyuse ngokuzenzakalelayo futhi lehlise izinga lokushisa.

I-2) Inqubo yokwelapha inqubo yokwelapha yakhiwe izinqubo ezintathu ezihlanganiswe ngokunembile: ukupholisa, ukushisa okuphansi kwe-ultra-low kanye nokukhuphuka kwezinga lokushisa.

Isizathu sokuthi kungani ukwelashwa kwe-cryogenic kungathuthukisa ukusebenza kuhlaziywa kanje:

I-1) Yenza i-austenite enobulukhuni obuphansi ishintshe ibe yi-martensite enokuqina, ezinzile, ukumelana nokugqoka okuphezulu nokumelana nokushisa;

2) Ngokwelashwa kwezinga lokushisa eliphansi kakhulu, i-crystal lattice yezinto ezilashwayo inezinhlayiya ze-carbide ezisatshalaliswa kabanzi ezinobulukhuni obuphezulu kanye nosayizi wezinhlayiyana ocolekile;

3) Ingakwazi ukukhiqiza iyunifomu eyengeziwe, encane futhi eminyene kakhudlwana isakhiwo micro material okusanhlamvu metal;

I-4) Ngenxa yokwengezwa kwezinhlayiya ze-carbide ezincane kanye ne-lattice kakhudlwana, kuholela ekwakhiweni kwamangqamuzana aminyene, okunciphisa kakhulu ama-voids amancane endabeni;

I-5) Ngemuva kokwelashwa kwe-ultra-low lokushisa, ukucindezeleka kwangaphakathi kokushisa nokucindezeleka kwemishini yezinto ezibonakalayo kuyancipha kakhulu, okunciphisa ngokuphumelelayo amathuba okubangela ukuqhekeka nokuwa komphetho wamathuluzi nabasiki. Ngaphezu kwalokho, ngenxa yokuthi ukucindezeleka okusele kuthuluzi kuthinta ikhono lokusika ukuze lithole amandla e-kinetic, ithuluzi eliphathwa ekushiseni kwe-ultra-low aligcini nje ukumelana nokugqoka okuphezulu, kodwa futhi nokucindezeleka kwalo okusalayo akuyingozi kakhulu kunethuluzi elingelashwa;

I-6) Ku-carbide enosimende ephathwayo, ukuncishiswa kwamandla e-kinetic kagesi kuholela ekuhlanganiseni okusha kwezakhiwo zamangqamuzana.
