Me yasa samfuran Tungsten Carbide ke raguwa bayan Sintering?

Tungsten carbide yana daya daga cikin shahararrun kayan aiki a cikin masana'antar zamani. A cikin masana'anta, koyaushe muna amfani da ƙarfe na foda don kera samfuran carbide tungsten. A cikin sintering, zaku iya gano cewa samfuran tungsten carbide sun ragu. Don haka menene ya faru da samfuran carbide tungsten, kuma me yasa samfuran tungsten carbide suka ragu bayan sintering? A cikin wannan labarin, za mu bincika dalilin.

Samar da samfuran carbide tungsten

1. Zaɓi da siyan 100% albarkatun kasa, tungsten carbide;

2. Haɗa tungsten carbide foda tare da foda cobalt;

3. Nika gauraye foda a cikin injin hadawa ball da wani ruwa kamar ruwa da ethanol;

4. Fesa bushewa da rigar foda;

5. Compacting foda a cikin nau'i daban-daban da girma bisa ga bukatun abokan ciniki. Hanyoyin latsa masu dacewa suna yanke shawarar nau'ikan da girman samfuran tungsten carbide;

6. Sintering a cikin sintering tanderu;

7. Binciken ingancin ƙarshe.

Matakan sintering tungsten carbide kayayyakin

1. Cire na'urar gyare-gyare da kuma matakin farko na ƙonawa;

A wannan mataki, ma'aikaci ya kamata ya sarrafa zafin jiki don karuwa a hankali. Yayin da zafin jiki ya karu a hankali, danshi, iskar gas, da sauran sauran ƙarfi a cikin ƙwayar tungsten carbide za su ƙafe, don haka wannan mataki shine cire kayan gyare-gyare da sauran abubuwan da suka rage da kuma ƙonewa. Wannan mataki yana faruwa a kasa da 800 ℃

2. M-lokaci sintering mataki;

Yayin da zafin jiki ya ƙaru kuma ya zarce 800 ℃, ya juya zuwa mataki na biyu. Wannan mataki yana faruwa kafin ruwa ya wanzu a wannan tsarin.A cikin wannan mataki, ƙwayar filastik tana ƙaruwa, kuma jikin da aka lalata yana raguwa sosai.Tungsten carbide raguwa za a iya lura da gaske, musamman sama da 1150 ℃.

Cr. Sandvik

3. Liquid-lokaci sintering mataki;

A lokacin mataki na uku, yawan zafin jiki zai karu zuwa zafin jiki mai zafi, mafi girman zafin jiki yayin sintering. An gama raguwa da sauri lokacin da yanayin ruwa ya bayyana akan tungsten carbide kuma porosity na tungsten carbide yana raguwa.

4. Matakin sanyaya.

Ana iya cire carbide da aka yi da siminti bayan sintiri daga cikin tanderun da aka sanyaya a sanyaya zuwa zafin jiki. Wasu masana'antu za su yi amfani da zafin datti a cikin tanderun da aka yi amfani da su don sabon amfani da zafi. A wannan lokaci, yayin da zafin jiki ya ragu, an kafa microstructure na ƙarshe na gami.

Idan kuna sha'awar samfuran carbide tungsten kuma kuna son ƙarin bayani da cikakkun bayanai, zaku iya tuntuɓar mu ta waya ko wasiƙa a hagu, ko Aika wasiƙun Amurka a kasan shafin.
