Muaj ntau hom iav hauv kev tsim khoom, suav nrog lub hnub iav, iav ncaj, iav ob chav, iav sab hauv, iav sab nrauv, thiab iav bevel.
Kev tsim cov hmoov metallurgy iav yuav tsum xub paub meej cov ntaub ntawv.Muaj ntau cov qauv nruab nrab rau cov khoom siv hmoov metallurgy.Raws li Nyiv, Tebchaws Meskas thiab Lub Tebchaws Yelemees yog tus thawj coj hauv ntiaj teb hauv kev tshawb fawb hmoov metallurgy, tam sim no muaj ntau yam khoom siv rau JIS, MPIF, thiab DIN cov qauv khoom.
Gears feem ntau muaj qee qhov kev xav tau rau lub zog, yog li kev ua haujlwm ntawm cov ntaub ntawv xaiv yuav tsum ua tau raws li cov khoom xav tau.Tam sim no, cov ntaub ntawv siv ntau dua rau cov iav yog Fe-Cu-C-Ci cov ntaub ntawv (raws li JIS SMF5030, SMF5040, thiab MPIF FN-0205, FN-0205-80HT tus qauv) Fe-Cu-C cov ntaub ntawv kuj muaj.
Qhov ntom ntawm cov hmoov hlau metallurgy iav, vim tias cov iav siv rau kev sib kis, muaj cov kev xav tau ntau dua rau lub zog ntawm lub zog, yog li qhov ceev ntawm cov khoom yuav kuj siab, thiab cov hniav kuj yuav txhim kho thiab lub zog yuav siab dua.
Lub hardness ntawm hmoov metallurgy iav yog ze ze rau cov khoom siv, qib ceev thiab tom qab ua tiav ntawm cov khoom.Yog li thaum koj yuav cov iav, qhov hardness ntau yam yuav tsum tau qhia hauv daim duab.
Tom qab cov iav yog sintered, txhawm rau txhim kho lub zog thiab hnav tsis kam ntawm cov iav, cov txheej txheem tom qab ua tiav feem ntau yog ntxiv los txhim kho kev ua haujlwm.Feem ntau muaj ob txoj kev kho mob:
1. Kev kho dej vapor deg.Dej vapor reacts nrog Fe nyob rau saum npoo ntawm lub iav los tsim cov khoom ntom ntom Fe₃O₄.Fe₃O₄ muaj qhov nyuaj dua, uas tuaj yeem ua rau kom hnav tsis kam thiab qhov tawv tawv ntawm cov iav.
2. Carburizing kho
Ib yam li cov kev kho mob carburizing ntawm cov cuab yeej siv tshuab zoo tib yam, carbonitriding thiab quenching yog siv ntau zaus los txhim kho qhov tawv tawv ntawm lub zog.
