Sorbitized (5.50) chaiyo simbi pombi yezvikamu zvemotokari.Zita rekutanga raive "lead quenching method".Kubva kuma1950s, nyika yedu yakapisa waya yesimbi kune austenitizing tembiricha, uye ndokuinyudza mubhati rekutungamirira pakudziya padyo nemhino yeisothermal shanduko dhiyagiramu.Iyo isothermal tembiricha inochengetedzwa kusvika iyo austenitic decomposition yapera, uyezve iyochaiyo simbi pombiinonyanya kushandiswa kune zvikamu zvemotokari inotorwa kunze uye yakatonhodzwa mumhepo kuti iwane yese kana yakawanda yeiyo sorbite chimiro.Kuzvipisa uye kudziya kwega (6.4) (6.5).
Kare, pakanga paine izwi rekuti "kupisa kwepamhepo", izvo zvainzwisiswa zvichireva kuti mushure mekudzima kwepamusoro kwepombi yesimbi chaiyo yezvikamu zvemotokari, zvikamu zvakadzimwa zve.kunyatsoita seamless pombinekuti zvikamu zvemotokari zvaipisa nekudzikamiswa nekuda kwekupisa kwekunze kwemoyo.Nekudaro, kubva pakuongorora kwakadzama kweyakaderera-kabhoni martensite, inowanikwa kuti nekuda kwekukwira kwayo Ms point, kudziya kunongoitika kunoumbwa mukudzima kwe.precision simbi mapaipi emotokari accessories, iyo inodaidzwa kuti kukurumidza kupisa.Iyi ndiyo nzira yekupisa kupisa kubva pakati peiyo chaiyo mota simbi mapaipi kusvika pamusoro uye kudziyisa nekudziya.Kugadzikana kwechisikigo (kana kugadzikana kwechisikigo kurapwa) (7.8).
Kukandwa kwakaiswa mumhepo yakashama kwenguva yakareba kunokonzeresa kuzorora kwekushushikana, nekudaro kudzikamisa chimiro uye saizi yekukanda, iyo inowanzonzi kuchembera kurapwa kuChina.Kunyangwe izwi rechirungu rekuti "seasoning" rinogona kududzirwa se "kuchembera", kuchembera kwakatsanangurwa zvakajeka muhunyanzvi hwekupisa kupisa kwepaipi yesimbi yezvimiro zvesimbi uye zvikamu zvemotokari, ndiko kuti, mushure mekugadziriswa kwemhinduro kana kutonhora kwepurasitiki deformation, kuita kwayo kunoshanduka nenguva kana ichiiswa patembiricha yekamuri kana patembiricha yakakwira zvishoma.
Shanduko yekushanda kweiyo chaiyo simbi pombi zvinhu zvinonyanya kushandiswa kune zvikamu zvemotokari mushure mekuchembera ndiko kunaya kwezvimedu zvinoumbwa nechikamu chakapararira, kusasanganisa kuzorora kana kubviswa kwekushushikana kwemukati.Kuti udzivise nyonganiso, makanda achanzi "kugadzikana (kana kwechisikigo) kugadzikana" pachinzvimbo che "kuchembera".Carbon content kugovera (8.23).Iyo kabhoni yemukati yeakakosha chaiyo simbi pombi yezvikamu zvemotokari inoreva iyo kabhoni yemukati mune yese kana chikamu chezvikamu zvesimbi, asi hapana fomu inogumira.Yayo kabhoni yekumisikidza inogumira kune yakasimba mhinduro mu α Iron kana γ Carbon yemukati yesimbi.
Carbides anowanzo kuoneka pamusoro carburized pamusoro alloy simbi motokari precision simbi machubhu, kunyanya carbide yakasimbisa carburizing (8.14) yakagadzirwa mumakore achangopfuura.Nokudaro, zvakakodzera kutora kabhoni yemukati sehuwandu hwekutaura kwekabhoni yemukati mu carburized layer.Carbon chiitiko (8.27).Chirevo chemuviri chechiitiko ndiko kusungirirwa kunoshanda kwechinhu chakapihwa solute mune yakapihwa mhinduro (kana yakasimba mhinduro).Carburizing yemapombi esimbi chaiwo ezvikamu zvemotokari anowanzo itwa muaustenitic state, saka kabhoni kabhoni yesimbi carburizing kazhinji inoreva kugadzikana kwekabhoni muaustenite.
Izvo zvinofanirwa kutaurwa kuti chiitiko uye chiitiko coefficient yekabhoni muferrite haifanirwe kuverengerwa nekushandisa empirical mafomula pakuda.Terminology yekurapa pamusoro peiyo chaiyo inopenya machubhu emotokari.Nekuti iko kurapwa kwepamusoro kwepombi dzesimbi dzezvikamu zvemotokari tekinoroji yakashandiswa zvakanyanya muindasitiri yezvinhu nhasi, mazwi elaser cladding (12.1), laser shock treatment (12.2), micro arc oxidation (12.3), ion implantation (12.1). 12.4), intense pulsed electron beam irradiation (12.20), plasma spraying (12.21), thermal spraying (12.22) nemamwe mazwi ane hukama akawedzerwa pahwaro hwemashoko echinyorwa cha1999.Pahwaro uhwu, isu takagadzirisa zvirevo zveaya ekufambisa mota shaft precision simbi machubhu,uye vaita basa rakanaka muinjiniya yepasi uye composite kupisa kurapwa kwematemu ekuisa
