Imboni yokwelapha ukushisa

Uhlolojikelele Lokwelashwa Kokushisa

Ukwelashwa kokushisa kuyinqubo esebenzisa ukushisisa okulawulwayo nokupholisa ukushintsha ukwakheka kwekristalu yezinsimbi nama-alloys ensimbi (okufana nensimbi ne-aluminium).Ngokuhamba kwesikhathi, kuye kwasungulwa izindlela eziningi ezihlukahlukene.Ngokuya ngenqubo yezinto ezibonakalayo kanye nokwelashwa, ukwelashwa kokushisa kunganikeza izinzuzo eziningi,okuhlanganisa ubulukhuni obuningi, ukumelana nokushisa okuthuthukisiwe, i-ductility ethuthukisiwe, namandla amakhulu wezinto ezibonakalayo.

Nakuba abantu abaningi bengazi ukuthi kuyini ukwelapha ukushisa, empeleni kuyingxenye ebalulekile yenqubo yokukhiqiza.Ingasetshenziswa ezigabeni ezahlukene zenqubo yokukhiqiza ukushintsha izakhiwo ezithile zensimbi noma i-alloy.Ezinye izimboni eziphawulekayo lapho ukwelashwa kokushisa kudlala indima ebalulekile zifakaindiza, izimoto, hardware(njengamasaha nezimbazo),amakhompyutha, imikhumbi-mkhathi, ezempi, kanye nemboni kawoyela negesi.

Kusebenza Kanjani Ukwelashwa Kokushisa?

Ishadi Lokugeleza Kokwelashwa Kokushisa

Kwashiwo ngaphambili ukuthi ukwelapha ukushisa empeleni kuwukuguqulwa kwezinto ezibonakalayo zensimbi ngokushisisa okulawulwayo noma ukupholisa, futhi empeleni ukwelashwa kokushisa kusebenza kulowo mgomo olula.Nakuba kunezinhlobo eziningi zokwelapha ukushisa, zilandela inqubo efanayo.Kafushane nje,ukwelashwa kokushisa kusebenza ngokushisisa insimbi, ukuyibamba kulelo zinga lokushisa, bese uyipholisa ibuyele phansi.Isizathu sokuthi izakhiwo zezingxenye zensimbi zishintsha phakathi nale nqubo ukuthi amazinga okushisa aphezulu ashintsha i-microstructure yensimbi, edlala indima ebalulekile emisebenzini yemishini yezinto ezibonakalayo.

Ubude besikhathi insimbi ifudunyezwa ngayo ibizwa ngokuthi “isikhathi sokuphumula“.Ubude besikhathi sokucwiliswa budlala indima ebalulekile ezakhiweni zensimbi, ngoba i-microstructure yensimbi efakwe isikhathi eside ishintsha ngokuhlukile kunaleyo yensimbi efakwe isikhathi esifushane.Ngakolunye uhlangothi, inqubo yokupholisa ngemva kwesikhathi sokucwilisa nayo inomthelela emphumeleni wensimbi.Insimbi ingapholiswa ngokushesha, okubizwa ngokuthi i-quenching, noma ingapholiswa kancane esithandweni ukuze kuqinisekiswe ukuthi imiphumela oyifunayo iyafinyelelwa.Inhlanganisela yezinga lokushisa lokucwilisa, isikhathi sokucwilisa, izinga lokushisa lokupholisa kanye nobude bokupholisa konke kudlala indima ekukhiqizeni izici ezifiselekayo kunsimbi noma ingxubevange.

Ukufingqa, inqubo yokwelapha ukushisa idinga izinyathelo ezintathu eziyisisekelo,ukufudumeza, ukucwiliswa, nokupholisa.

Izigaba Zokushisa

I-microstructure ye-alloy iyashintsha phakathi nenqubo yokwelapha ukushisa.Ukushisisa kulandela iphrofayili ethile yokushisa.Kuleli qophelo insimbi ingase ibe ezifundeni ezintathu ezihlukene, ingxube yemishini, isixazululo esiqinile, noma inhlanganisela yakho kokubili.Isimo ngasinye siletha izimfanelo ezihlukene futhi isimo singashintshwa ngokushisa ngokusho komdwebo wesigaba.

Isiteji Sokucwila

Inhloso yesigaba sokucwilisa ukugcina insimbi ekushiseni okufanele kuze kube yilapho kwakhiwa isakhiwo sangaphakathi esifunwayo.Ubude besikhathi buncike ezidingweni.Isibonelo, uhlobo lwezinto kanye nobukhulu bengxenye, lapho ubukhulu bengxenye bukhulu, isikhathi esiningi siyadingeka.Ingqikithi yezingxenye eziningi ithatha isikhathi eside ukufinyelela izinga lokushisa elidingekayo.

Isiteji Sokupholisa

Phakathi nesigaba sokupholisa, udinga ukupholisa insimbi emuva ekamelweni lokushisa, kodwa kunezindlela ezahlukene zokwenza lokhu kuye ngohlobo lwensimbi.Kungase kudinge indawo yokupholisa, igesi, uketshezi, okuqinile noma inhlanganisela yakho.Izinga lokupholisa lincike ensimbi ngokwayo kanye nendawo yokupholisa.Ngakho-ke, ukukhetha okwenzayo ekupholiseni kuyisici esibalulekile ekusebenzeni okufunayo kwensimbi.

Izindlela kanye Nezinzuzo Ezivamile Zokwelapha Ukushisa

Ziningi izindlela zokwelapha ukushisa ongakhetha kuzo.Ngamunye wabo uphethe izimfanelo ezithile.Izindlela ezivame kakhulu zokwelapha ukushisa zihlanganisa:

Ukuqina

Enye yezindlela ezivame kakhulu zokwelapha ukushisa,lokhu kwandisa ubulukhuni bensimbi noma i-alloy futhi kuyenze ibe i-ductile encane.Ngokujwayelekile, ukuze kuqiniswe ingaphezulu ngaphandle kokwenza ukuqina okulandelayo, okuvame ukwaziwa nangokuthi i-nitriding, ukusakazeka kwe-nitrogen ebusweni bezinsimbi ezikhethekile ze-alloy, okuholela ekubeni indawo eqinile nenkango ethambile ngaphandle kokwelashwa okwengeziwe.

Ukuthukuthela

I-Tempering iyinqubo yokunciphisa ubulukhuni obudlulele kanye nokuqina okubangelwa ngesikhathi sokuqina.Izingcindezi zangaphakathi nazo ziyakhululeka.Ngokuvamile, ukuthambisa kuyisinyathelo sokugcina senqubo yokuqina.Kuyinqubo yokwelapha ukushisa esiza ukuthuthukisa ukunwebeka kwensimbi.Ama-alloys asekelwe ku-ayoni ngokuvamile aqinile, kodwa ngokuvamile aba brittle kwezinye izinhlelo zokusebenza.Ukushisa kusiza ukuguqula ubulukhuni, ukuqina kanye ne-ductility yensimbi.Lokhu ukwenza inqubo ibe lula.

Anealing

I-Annealing ithambisa insimbi.Kwenza insimbi ifaneleke kakhulu ekusebenzeni okubandayo nokwenza.Iphinde ithuthukise ukusebenziseka, i-ductility kanye nokuqina kwe-metal.Enqubweni ye-annealing, insimbi iyashiswa ngaphezu kwezinga lokushisa elibucayi eliphezulu bese ipholiswa ngesilinganiso esincane.

Ukujwayela

Ukujwayela kungenye indlela yokudonsa.Isetshenziselwaukukhulula ukucindezeleka kwangaphakathi okubangelwa izinqubo ezifana nokushisela, ukuphonsa noma ukucisha. Insimbi evamile iqinile futhi inamandla kunensimbi efakwe emanzini.Kule nqubo, insimbi iyashiswa ekushiseni okungama-40 ° C ngaphezu kokushisa kwayo okuphezulu okubalulekile.Kulokhu, insimbi ifudunyezwa ku-200 ° F, ngaphezu kwezinga lokushisa le-annealing.Uchwepheshe ugcina insimbi ekushiseni okubalulekile kuze kube yilapho kwenzeka ukuguqulwa.Le nqubo yokwelapha ukushisa idinga ukupholisa komoya ngemva kokushisa.

Njengomholi ekwelapheni ukushisa, i-ProLean Hub inikeza izinhlobonhlobo zezinsizakalo zokwelapha ukushisa.Izikhungo zethu ziphatha izingxenye zabo bonke osayizi ngezindinganiso eziqinile futhi zilethe imiphumela ethembekile, ephindaphindwayo.Imisebenzi yethu yokwelapha ukushisa iphethwe abanye onjiniyela nabachwepheshe abangcono kakhulu embonini, abanolwazi nobungcweti bokunikeza ukwesekwa okubalulekile nokuqonda kweqiniso izidingo zamakhasimende ethu.Ungavakashela wethuIkhasi Lokwelapha Ukushisaukuze uthole ulwazi olwengeziwe, noma ungakwazikhuluma ngqo nomunye wonjiniyela bethu.
