Sorbitized (5.50) umbhobho yentsimbi echanekileyo kwiindawo zemoto.Igama lokuqala laliyi "lead quenching method".Ukususela kwiminyaka yee-1950, ilizwe lethu liye lafudumeza ucingo lwentsimbi kwiqondo lokushisa le-austenitizing, kwaye liyifake kwibhafu yokukhokela kwiqondo lokushisa elikufutshane nempumlo yomzobo wenguqu ye-isothermal.Ubushushu be-isothermal bugcinwa de ukubola kwe-austenitic kugqityiwe, kwaye emva kokoumbhobho wentsimbi echanekileyongokukodwa isetyenziselwa iindawo zemoto ikhutshwa kwaye ipholiswe emoyeni ukufumana yonke okanye uninzi lwesakhiwo se-sorbite.Ukuzifudumeza kunye nokufudumeza okuzenzekelayo (6.4) (6.5).
Ngaphambili, kwakukho igama eliqhelekileyo elithi "ukutsha okuzenzekelayo", okuqondwa ukuba kuthetha ukuba emva kokucinywa kwendawo yombhobho wentsimbi echanekileyo kwiindawo zemoto, iindawo ezicinyiweyoumbhobho ochanekileyo ongenamthungokuba iindawo zemoto zazifudunyezwa kwaye zifudunyezwa ngenxa yokuqhutywa kobushushu ngaphandle entliziyweni.Nangona kunjalo, kuphononongo olunzulu lwe-low-carbon martensite, kufumaniseke ukuba ngenxa yenqanaba eliphezulu likaMs, ubushushu buvela ngokuzenzekelayo kwinkqubo yokucima.imibhobho yentsimbi echanekileyo yezincedisi zemoto, okubizwa ngokuba kukucaphuka okuzenzekelayo.Le yinkqubo yokudluliselwa kobushushu ukusuka kwisiseko semibhobho yentsimbi yemoto echanekileyo ukuya kumphezulu kunye nokufudumeza ngokufudumeza.Ukuzinzisa kwendalo (okanye unyango lozinzo lwendalo) (7.8).
Ukuphosa okubekwe kwindawo evulekileyo ixesha elide kuya kubangela ukuphumla koxinzelelo, ngaloo ndlela kuzinzisa imilo kunye nobukhulu bokuphosa, okubizwa ngokuba kunyango lokuguga e-China.Nangona igama lesiNgesi elithi "i-seasoning" linokuguqulelwa ngokoqobo ngokuthi "ukuguga", ukuguga kuye kwachazwa ngokucacileyo kwinkqubo yonyango lobushushu lwemibhobho yentsimbi echanekileyo yezakhiwo zetsimbi kunye neengxenye zemoto, oko kukuthi, emva konyango lwesisombululo okanye ukuguqulwa kweplastiki ebandayo, ukusebenza kwayo kuyatshintsha kunye nexesha xa ibekwe kwiqondo lobushushu begumbi okanye kwiqondo lobushushu eliphezulu kancinane.
Ukutshintshwa kokusebenza kwezinto ezichanekileyo zombhobho wensimbi ezisetyenziselwa ngokukodwa iinxalenye zemoto emva kokuguga yimvula yeengqungquthela ezenziwe ngokusasazwa kwecandelo, ngaphandle kokuphumla okanye ukupheliswa koxinzelelo lwangaphakathi.Ukuze kuthintelwe ukubhideka, iicastings ziya kubizwa ngokuba "zinzo lwendalo (okanye lwendalo) endaweni yelithi "ukuguga".Ukuhanjiswa komxholo weCarbon (8.23).Umxholo wekhabhoni wombhobho wensimbi ochanekileyo ochanekileyo kwiingxenye zemoto ubhekisela kumxholo wekhabhoni kuyo yonke okanye inxalenye yeengxenye zetsimbi, kodwa akukho fom eqingqiweyo.I-carbon concentration yayo ikhawulelwe kwisisombululo esiqinileyo kwi-α Iron okanye i-γ ye-Carbon content yentsimbi.
Iikhabhidi zihlala zivela kumphezulu wentsimbi yentsimbi yentsimbi echanekileyo, ngakumbi i-carbide eyomeleziweyo ye-carburizing (8.14) ephuhliswe kwiminyaka yakutshanje.Ngoko ke, kuyafaneleka ukuthatha umxholo wekhabhoni njengenkcazo yobungakanani bomxholo wekhabhoni kwi-carburized layer.Umsebenzi wekhabhoni (8.27).Intsingiselo yomzimba womsebenzi kukugxininiswa okusebenzayo kwe-solute enikiweyo kwisisombululo esinikiweyo (okanye isisombululo esiqinileyo).Ukungcwatywa kwemibhobho yentsimbi echanekileyo yeendawo zemoto ngokuqhelekileyo kwenziwa kwi-austenitic state, ngoko ke umsebenzi wekhabhoni wentsimbi yentsimbi ubhekiselele kuxinzelelo olusebenzayo lwekhabhoni kwi-austenite.
Kufuneka kuphawulwe ukuba umsebenzi kunye ne-coefficient ye-carbon kwi-ferrite akufanele ibalwe ngokusebenzisa iifomyula ezinobungqina ngokuthanda.Isigama sonyango lomphezulu lwetyhubhu eziqaqambileyo ezichanekileyo kwiimoto.Ngenxa yokuba unyango lomphezulu lwemibhobho yentsimbi echanekileyo yeendawo zemoto bubuchwephesha bokuguqulwa obusetyenziswa kakhulu kwishishini lezinto eziphathekayo namhlanje, imimiselo ye-laser cladding (12.1), unyango lokutshatyalaliswa kwe-laser (12.2), i-arc oxidation encinci (12.3), i-ion implantation ( 12.4), i-pulsed electron beam irradiation (12.20), i-plasma spraying (12.21), i-thermal spraying (12.22) kunye neminye imigaqo ehambelana nayo yongezwa ngokwemigaqo ye-1999 edition.Ngesi siseko, siye sahlengahlengisa imiqathango yolu kuhanjiswa kweemoto iityhubhu zentsimbi ezichanekileyo,kwaye benze umsebenzi olungileyo kubunjineli bomphezulu kunye nonyango lobushushu oluhlanganisiweyo lwemiqathango yokubeka
