Menene Hot Isostatic Pressing (HIP)?

Lokacin da muke kera samfuran carbide tungsten, ya kamata mu zaɓi mafi kyawun albarkatun ƙasa, tungsten carbide foda da foda mai ɗaure, yawanci cobalt foda. Mix da niƙa su, bushewa, latsawa, da kuma sintiri. A lokacin sintering, koyaushe muna da zaɓi daban-daban. Kuma a cikin wannan labarin, za mu yi magana game da zafi isostatic latsa sintering.

Mene ne Hot Isostatic Latsawa?

Hot Isostatic Pressing, kuma aka sani da HIP, yana ɗaya daga cikin hanyoyin sarrafa kayan. A lokacin zafi isostatic latsa sintering, akwai babban yanayin zafi da isostatic matsa lamba.

Gas da aka yi amfani da shi a cikin zafi mai zafi isostatic matsi sintering

Ana amfani da iskar gas na Argon a cikin matsi mai zafi na isostatic. A cikin tanderun wutar lantarki, akwai yanayin zafi da matsanancin matsin lamba. Argon gas yana yiwuwa ya haifar da ƙaƙƙarfan convection saboda ƙarancin ƙima da ƙima na danko, da kuma yawan haɓakar haɓakar thermal. Sabili da haka, ma'auni na canja wurin zafi na kayan aiki mai zafi na isostatic yana da girma fiye da na tanderun gargajiya.

Aikace-aikace na zafi isostatic latsa sintering

Ban da kera samfuran carbide tungsten, akwai wasu aikace-aikace na matsi mai zafi na isostatic sintering.

1. Matsa lamba sintering na iko.

Misali. Ana yin allunan ne ta hanyar matsi mai zafi mai zafi don yin wani ɓangare na jirgin sama.

2. Yaduwa bonding na daban-daban iri kayan.

Misali. Ana yin tarukan makamashin nukiliya ta hanyar matsananciyar isostatic sintering don amfani da su a cikin injinan nukiliya.

3. Cire ragowar ramuka a cikin abubuwan da aka lalata.

Misali. Tungsten carbide da sauran kayan, irin su Al203, ana yin su ta hanyar matsi mai zafi mai zafi don samun babban kaddarorin, kamar tauri mai ƙarfi.

4. Cire lahani na ciki na simintin gyaran kafa.

Al da superalloys ana yin su ta hanyar latsawa mai zafi na isostatic don cire lahani na ciki.

5. Gyaran sassan da kasala ko rarrafe suka lalace.

6. Hanyoyin da ake amfani da su na carbonization na matsa lamba.

Daban-daban kayan don kerawa a cikin matsin isostatic mai zafi

Tunda zafi isostatic latsa sintering yana da aikace-aikace da yawa, ana iya amfani dashi don kera nau'ikan kayan. Daban-daban kayan suna da halaye na jiki da na sinadarai daban-daban, don haka suna da buƙatu daban-daban don yanayin sintering. Dole ne mu canza yanayin zafi da matsa lamba na abubuwa daban-daban. Misali, Al2O3 yana buƙatar 1,350 zuwa 1,450°C da 100MPa, kuma Cu alloy yana neman 500 zuwa 900°C da 100MPa.

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.
