1. Tso dej
Hmoov metallurgy Cheebtsam yog inherently ntxeem tau.Impregnation, tseem hu ua kev nkag mus, suav nrog ntau qhov pores nrog cov khoom hauv qab no: yas, resins, tooj liab, roj, lwm yam khoom.Muab cov khoom ntxeem tau nyob rau hauv lub siab tuaj yeem ua rau cov dej ntws tawm, tab sis yog tias koj tsau ib feem, nws yuav dhau los ua impermeable rau siab.Cov ntaub ntawv siv rau impregnated qhov chaw nyob ntawm seb yam xws li nqi thiab daim ntawv thov.Piv txwv li, tooj liab yuav o thaum lub sij hawm sintering, yog li rhuav tshem qhov seem stability.Immersion nyob rau hauv cov roj yuav cia li lubricate qhov chaw.Txhua yam nyob ntawm koj tus qauv tsim.
2. Electroplating
Electroplating yog ib qho kev xaiv rau stainless hlau rau kev zoo nkauj los yog kev xav tau - ua qhov chaw pom kev zoo nkauj, txhim kho corrosion, thiab lwm yam. Plating muab cov khoom zoo rau koj thaum tso cai rau koj "sandwich" cov ntaub ntawv pheej yig dua rau hauv cov khoom qub.
3. Tua peening
Kev txhaj tshuaj peening yog txheej txheem densification hauv zos, uas tuaj yeem txhim kho qhov chaw ntawm qhov chaw los ntawm kev tshem tawm cov burrs thiab siv qhov chaw compressive kev nyuaj siab rau qhov chaw.Qhov no tej zaum yuav muaj txiaj ntsig zoo hauv qee qhov kev siv qaug zog.Xuab zeb blasting kuj tsim cov pits me me uas ntxiab roj nplua nyeem rau ntawm qhov chaw.Kev qaug zog tawg feem ntau yog pib los ntawm qhov tsis xws luag.Kev txhaj tshuaj peening tuaj yeem tiv thaiv qhov tsim ntawm cov kab nrib pleb thiab tuaj yeem ncua kev txhim kho ntawm tag nrho cov kab nrib pleb.
4. Chav kho mob
Thaum siv rau cov khoom siv hlau, chav kho mob yuav tsim ib txheej nyias thiab tawv oxide.oxide txheej tsis xeb;Nws yog ib yam khoom uas adheres rau hlau.Cov txheej no tuaj yeem txhim kho corrosion kuj, siab tsis kam thiab hardness
