Tungsten Carbide Hniav thiab Txheej

Peb txhua tus paub tias hardness yog qhov tseem ceeb rau cov neeg siv khoom ntawm tungsten carbide hniav. Cov hniav nrog lub siab tawv tuaj yeem ua rau muaj kev hloov pauv sai, kev ua haujlwm nrawm, kev pabcuam lub neej, thiab lwm yam. Tab sis yuav ua li cas kom cov cuab yeej nyuaj yog qhov nyuaj vim tias tsis yog txhua yam cuab yeej tsim los ntawm cov tuam ntxhab thiab muag hauv khw muaj cov txiaj ntsig ntawm hardness. Ntau qhov yuav tsum tau ua kom txaus siab rau hom milling cutter qhov hardness nce. Ib qho yog siv cov khoom zoo.

Qhov no yog qhov tseem ceeb ua ntej, tab sis ntau lub tuam txhab siv cov khoom siv subpar tungsten carbide, vim tias lawv tus kheej cov kev cai tsim khoom tsis tau raws li lossis txiav cov nqi. Raws li qhov tshwm sim, nws nyuaj kom ua tiav qhov hardness zoo dua vim tias cov khoom tsis muaj hardness thiab nws nyuaj rau cov cuab yeej los ua kom pom qhov hardness. Cov chaw tsim khoom txiav txim siab hom tungsten carbide khoom siv. Ib qho yog tias cov chaw tsim khoom yuav tsum muaj peev xwm hloov kho nws cov zis thiab muaj lub koob npe zoo sib xws. Cov ntaub ntawv zoo tungsten carbide tsuas yog siv los lav lub cuab yeej hardness yog tias ob qhov tseem ceeb no tau ua tiav.

Nrog rau kev nce qib ntawm cov khoom siv, cov cuab yeej hardness tungsten carbide kuj tseem xav tau cov khoom siv tes ua ntau dua vim tias, txawm tias cov ntaub ntawv tungsten carbide zoo npaum li cas, lawv yuav tsum zoo dua thaum cov khoom siv tes ua tau raws li qhov xav tau. Cov kev xav tau ntau lawm, piv txwv li, ua rau nws nyuaj los kho qhov qub hardness ntawm high-zoo tungsten carbide tom qab degradation vim qhov kub thiab txias thiab cov chaw tsim khoom tsis muaj peev xwm tsim cov khoom. Muaj ntau qhov chaw kub kub siv hauv kev tsim thiab vuam txheej txheem siv los ua cov cuab yeej no. Yog tsis muaj kev siv tshuab siab heev, qhov kub siab yuav ua rau cov khoom siv tungsten carbide degrade.

Ntxiv ntau txheej txheej kuj yuav muaj qhov sib txawv. Txheej tungsten carbide muaj ob txoj hauv kev: ib qho yog CVD, thiab lwm qhov yog PVD. Lub hauv paus ntsiab lus ntawm cov tshuaj vapor deposition yog cov tshuaj tiv thaiv thermally induced nyob rau saum npoo ntawm rhuab tungsten carbide hniav, uas yog tsim los hloov mus rau cov ntaub ntawv tshiab thiab semiconductor kev lag luam. PVD yog cov txheej txheem vaporization los tso cov txheej txheem nyias ntawm cov khoom siv tungsten carbide hniav. Coatings muaj siab hardness thiab hnav tsis kam. Piv nrog tungsten carbide hniav tsis muaj coatings, tungsten carbide hniav nrog coatings tuaj yeem ua haujlwm ntawm kev txiav ceev dua, uas tuaj yeem txhim kho kev tsim khoom.

Yog tias koj txaus siab rau cov khoom lag luam tungsten carbide thiab xav paub ntau ntxiv thiab cov ntsiab lus, koj tuaj yeem tiv tauj peb hauv xov tooj lossis xa ntawv ntawm sab laug, lossis xa US MAIL hauv qab ntawm nplooj ntawv.
