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, ukucindezeleka kwangaphakathi kokushisa nokucindezeleka kwemishini yezinto ezibonakalayo kuyancipha kakhulu, okunciphisa ngokuphumelelayo amathuba okubangela ukuqhekeka nokuwa komphetho wamathuluzi nabasiki.Ngaphezu kwalokho, ngenxa yokuthi ukucindezeleka okusele ethuluzini kuthinta ikhono lokusika ukuze limunce amandla e-kinetic, ithuluzi eliphathwa ekushiseni okuphansi kakhulu aligcini nje ukumelana nokugqoka okuphezulu, kodwa futhi nokucindezeleka kwalo okusalayo akuyingozi kakhulu kunokungalashwa. ithuluzi;

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