Taw qhia:

Tungsten steel, tseem hu ua cemented carbide, hais txog cov khoom siv sib xyaw sintered uas muaj tsawg kawg yog ib qho hlau carbide. Tungsten carbide, cobalt carbide, niobium carbide, titanium carbide, thiab tantalum carbide yog cov feem ntau ntawm tungsten steel. Cov nplej loj ntawm cov khoom siv carbide (los yog theem) feem ntau yog nyob nruab nrab ntawm 0.2-10 microns, thiab cov nplej carbide tau tuav ua ke siv cov khoom siv hlau. Cov binder feem ntau yog hais txog cov hlau cobalt (Co), tab sis rau qee qhov kev siv tshwj xeeb, npib tsib xee (Ni), hlau (Fe), lossis lwm yam hlau thiab alloys kuj siv tau. Kev sib xyaw ua ke ntawm carbide thiab binder theem los txiav txim siab yog hu ua "qib".

Kev faib tawm ntawm tungsten steel yog ua raws li ISO cov qauv. Qhov kev faib tawm no yog nyob ntawm cov khoom siv ntawm cov khoom ua haujlwm (xws li P, M, K, N, S, H qib). Lub binder theem muaj pes tsawg leeg yog tsuas yog siv rau nws lub zog thiab corrosion kuj.

Lub matrix ntawm tungsten steel muaj ob feem: ib feem yog lub hardening theem; lwm qhov yog cov hlau sib txuas. Binder hlau feem ntau yog hlau pawg hlau, feem ntau siv cobalt thiab npib tsib xee. Yog li ntawd, muaj tungsten-cobalt alloys, tungsten-nickel alloys thiab tungsten-titanium-cobalt alloys.

Rau cov hlau uas muaj tungsten, xws li cov hlau ceev ceev thiab qee qhov kub ua haujlwm tuag steels, cov ntsiab lus tungsten hauv cov hlau tuaj yeem txhim kho qhov nyuaj thiab kub tsis kam ntawm cov hlau, tab sis lub toughness yuav poob sharply.

Kev siv lub ntsiab ntawm tungsten cov peev txheej kuj yog cemented carbide, uas yog, tungsten steel. Carbide, hu ua cov hniav ntawm kev lag luam niaj hnub, yog siv dav hauv tungsten steel khoom.

Cov khoom xyaw qauv

Sintering txheej txheem:

Sintering ntawm tungsten hlau yog nias cov hmoov rau hauv ib lub billet, ces nkag mus rau hauv lub sintering rauv kom sov rau ib tug tej yam kub thiab txias (sintering kub), cia rau ib tug tej lub sij hawm (tuav lub sij hawm), thiab ces txias nws, thiaj li yuav tau txais. cov khoom siv tungsten steel nrog cov khoom xav tau.

Plaub theem pib ntawm tungsten steel sintering txheej txheem:

1. Nyob rau theem ntawm kev tshem tawm tus neeg sawv cev tsim thiab ua ntej sintering, lub cev sintered tau hloov pauv hauv qab no:

Kev tshem tawm ntawm tus neeg sawv cev molding, nrog qhov nce ntawm qhov kub thiab txias hauv thawj theem ntawm sintering, tus neeg sawv cev molding maj mam decomposes los yog vaporizes, thiab lub cev sintered raug tshem tawm. Hom, kom muaj nuj nqis thiab sintering txheej txheem sib txawv.

Cov oxides ntawm qhov chaw ntawm cov hmoov raug txo. Ntawm qhov kub thiab txias, hydrogen tuaj yeem txo cov oxides ntawm cobalt thiab tungsten. Yog tias tus neeg ua haujlwm raug tshem tawm hauv lub tshuab nqus tsev thiab sintered, cov tshuaj tiv thaiv carbon-oxygen tsis muaj zog. Kev sib cuag ntawm cov hmoov hmoov yog maj mam tshem tawm, cov hmoov hlau sib txuas pib rov qab thiab recrystallize, qhov diffusion nto pib tshwm sim, thiab lub zog briquetting zoo tuaj.

2. Khoom theem sintering theem (800 ℃ — eutectic kub)

Ntawm qhov kub thiab txias ua ntej cov tsos ntawm cov kua theem, ntxiv rau kev txuas ntxiv cov txheej txheem ntawm cov theem dhau los, cov tshuaj tiv thaiv-theem thiab diffusion yog intensified, cov yas ntws yog txhim khu kev qha, thiab sintered lub cev shrinks ho.

3. Ua kua theem sintering theem (eutectic kub - sintering kub)

Thaum cov kua theem tshwm nyob rau hauv lub cev sintered, lub shrinkage yog ua tiav sai sai, ua raws li crystallographic transformation los tsim cov qauv thiab cov qauv ntawm cov alloy.

4. Cua txias theem (sintering kub - chav tsev kub)

Nyob rau theem no, cov qauv thiab theem muaj pes tsawg leeg ntawm tungsten steel muaj qee qhov kev hloov pauv nrog cov cua txias sib txawv. Cov yam ntxwv no tuaj yeem siv los ua kom sov-trench tungsten steel los txhim kho nws lub cev thiab cov khoom siv kho tshuab.

Kev taw qhia txog kev thov

Tungsten steel belongs rau cemented carbide, tseem hu ua tungsten-titanium alloy. Lub hardness tuaj yeem ncav cuag 89 ~ 95HRA. Vim li no, cov khoom siv tungsten steel (cov tungsten steel watches) tsis yooj yim rau hnav, nyuaj thiab tsis ntshai ntawm annealing, tab sis nkig.
