Jiyya na Ƙarfe gama gari

Ma'anar jiyya na saman karfe

Yana nufin tsarin canza yanayin yanayi da halayen sashe da haɓaka haɗin sa tare da kayan matrix don saduwa da ƙayyadaddun ƙayyadaddun ayyukan aiki ta amfani da sabbin fasahohi a cikin ilimin kimiyyar lissafi na zamani, sunadarai, ƙarfe, da horon kula da zafi.

1. Metal Surface Modification

Ya ƙunshi hanyoyi masu zuwa: hardening surface, sandblasting, knurling, waya zane, polishing, Laser surface hardening.

(1) Karfe taurin

Hanya ce ta maganin zafi wacce ke inganta shimfidar saman da sauri da sauri don taurare saman ba tare da canza sinadarai na karfe ba.

(2) Karfe mai yashi

The workpiece surface da aka shafi high-gugu yashi da baƙin ƙarfe barbashi, wanda za a iya amfani da su inganta inji Properties na part da kuma canza surface jihar. Wannan aiki na iya inganta ingantaccen ƙarfin inji, juriya da kuma kawar da saura damuwa.

(3) Karfe saman mirgina

Shi ne a danna saman workpiece tare da nadi mai wuya a dakin da zafin jiki domin saman workpiece za a iya taurare da filastik nakasar don samun daidai da santsi surface.

(4) karfen da aka goge

A karkashin wani karfi na waje, ana tilasta karfe ta hanyar mutu. An danne ɓangaren ɓangaren ƙarfe don canza siffarsa da girmansa. Ana kiran wannan hanyar zanen waya. Dangane da buƙatun kayan ado, za a iya yin zanen waya zuwa zare iri-iri, kamar su madaidaiciya, damfara, wavy, da zare.

(5) karfen polishing

Gogewa hanya ce ta ƙarewa don gyaggyarawa saman wani yanki. Yana iya samun wuri mai santsi kawai ba tare da inganta daidaiton mashin ɗin ba. Ƙimar Ra na fuskar da aka goge na iya kaiwa 1.6-0.008 um.

(6) Ƙarfafawar ƙarfe na Laser

Ana amfani da katako na Laser da aka mayar da hankali don dumama kayan aikin da sauri sannan kuma da sauri sanyaya aikin don samun taurare da ƙarfi. Ƙarfafawar fuskar Laser yana da fa'idodin ƙananan nakasawa, aiki mai sauƙi, da ƙarfafa gida.

2. Karfe Alloying Technology

Ta hanyar zahiri, ana ƙara kayan ƙari zuwa matrix don samar da alloy Layer. Carburizing da nitriding na yau da kullun suna cikin wannan fasaha. Yana sanya karfen da mai shigar da kara a cikin dakin da aka rufe, yana kunna saman karfen ta hanyar dumama, kuma yana sanya carbon da nitrogen su shiga cikin matrix na karfe a cikin nau'in atom don cimma manufar hadawa.

(1) baƙar fata: Ana samar da fim ɗin baƙin ƙarfe ko shuɗi don ware iska daga lalatawar kayan aikin.

(2) phosphating: Wani electrochemical karfe surface jiyya Hanyar amfani da shi don kare tushe karafa ta depositing mai tsabta, ruwa-insoluble phosphates a saman workpieces immersed a cikin wani phosphating bayani.

Babu ɗayansu da ke shafar tsarin ciki na aikin aikin. Bambance-bambancen shine baƙin ƙarfe yana sa kayan aikin ya haskaka, yayin da phosphating yana ƙara kauri kuma yana dushe saman aikin. Phosphating ya fi kariya fiye da baƙar fata. Dangane da farashi, baƙar fata yawanci ya fi tsada fiye da phosphating.

(3) karfe shafi fasaha

Ana yin sutura ko sutura akan saman wani abu ta hanyoyin physicochemical. Ana amfani dashi sosai a cikin kayan aikin yankan carbide.

TiN shafi da TiCN shafi a kan karfe surface

Tin 'yan microns mai kauri Akan kayan aikin yankan da ke yanke jan ƙarfe ko ƙarfe mai laushi, kayan yawanci zinare ne.

Black titanium nitride coatings yawanci amfani da inda gogayya coefficient ne karami amma taurin ake bukata.

Abin da ke sama shine taƙaitaccen gabatarwar mu ga maganin saman ƙarfe. Idan kuna sha'awar samfuran carbide tungsten kuma kuna son ƙarin bayani da cikakkun bayanai, zaku iya tuntuɓar mu ta waya ko wasiƙa a hagu, ko Aika wasiƙun Amurka a kasan shafin.
