Qhov tseem ceeb ntawm Txheej Tungsten Carbide
Qhov tseem ceeb ntawm Txheej Tungsten Carbide
Txhawm rau tsim cov khoom lag luam tungsten carbide, peb yuav tsum npaj cov ntaub ntawv raw ua ntej, suav nrog tungsten carbide hmoov thiab binder hmoov. Tom qab ntawd peb yuav tsum sib tov thiab milling lawv nyob rau hauv lub pob milling tshuab, tshuaj tsuag lawv nyob rau hauv qhuav sprayer, thiab compact lawv mus rau hauv ib tug tej yam duab thiab loj. Tom qab cov txheej txheem, peb yuav tsum sinter lawv nyob rau hauv lub sintering rauv. Qhov no yog ua tiav kev tsim khoom los txhawb kev ua haujlwm ntawm tungsten carbide. Peb yuav harden tungsten carbide nrog qee qhov kev kho saum npoo. Kab lus no tsom mus rau txheej txheej tungsten carbide.
Kev tsim cov tungsten carbide workpiece xav tau lub sijhawm ntev. Thaum lub sijhawm tsim khoom, peb yuav npog tungsten carbide kom tsis txhob oxidation nyob rau hauv qhov kub thiab txias. Coated tungsten carbide muaj zog dua, hnav tsis kam, tshuaj lom neeg ruaj khov, thiab tsis muaj kev sib txhuam thiab thermal conductivity.
Txheej tungsten carbide muaj ob txoj hauv kev: ib qho yog CVD, thiab lwm qhov yog PVD.
Tshuaj vapor deposition tseem hu ua CVD luv luv. 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 cov khoom, uas kuj yog tsim los hloov mus rau cov ntaub ntawv tshiab thiab semiconductor kev lag luam.
Lub cev vapor deposition tseem hu ua PVD luv luv, uas yog cov txheej txheem vaporization los tso cov txheej txheem nyias ntawm cov khoom tungsten carbide. Nws ib txwm muaj plaub kauj ruam, evaporation, tsheb thauj mus los, tshuaj tiv thaiv, thiab tso tawm. Cov txheej txheem no yuav tshwm sim hauv lub tshuab nqus tsev vacuum thiab siv lub tshuab nqus tsev vacuum kom huv si thiab qhuav.
Coatings muaj siab hardness thiab hnav tsis kam. Piv nrog rau cov khoom tungsten carbide yam tsis muaj coatings, tungsten carbide cov khoom nrog coatings tuaj yeem ua haujlwm ntawm kev txiav nrawm dua, uas tuaj yeem txhim kho kev tsim khoom. Dab tsi ntxiv, thaum cov khoom siv tungsten carbide nrog thiab tsis muaj txheej txheej ua haujlwm ntawm tib lub sijhawm txiav, cov khoom siv tungsten carbide nrog cov txheej txheem muaj kev hnav zoo dua.
Feem ntau, tungsten carbide yuav tsum tau coated, tshwj xeeb tshaj yog tungsten carbide inserts. Cov txheej txheej ntawm tungsten carbide tuaj yeem txhim kho wettability thiab hardness thiab tiv thaiv tungsten carbide los ntawm kub, oxidation, thiab corrosion. Cov txheej txheem yog qhov tseem ceeb rau tungsten carbide.
Dhau li ntawm txheej txheej, kuj tseem muaj lwm txoj hauv kev los ua kom tawv tungsten carbide los ntawm kev kho qhov chaw, xws li plasma surfacing, supersonic spraying, gas shield welding, nplaim cladding, nqus cladding, thiab thermal diffusion hardening.
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.
