Kodi Hot Isostatic Pressing (HIP) ndi chiyani?

Pamene tikupanga tungsten carbide mankhwala, tiyenera kusankha bwino zopangira, tungsten carbide ufa ndi binder ufa, kawirikawiri cobalt ufa. Sakanizani ndi mphero iwo, kuyanika, kukanikiza, ndi sintering. Panthawi ya sintering, timakhala ndi zosankha zosiyanasiyana. Ndipo m'nkhaniyi, tikambirana za kutentha kwa isostatic pressing sintering.

Kodi Hot Isostatic Pressing ndi chiyani?

Hot Isostatic Pressing, yomwe imadziwikanso kuti HIP, ndi imodzi mwazinthu zopangira zinthu. Pa kutentha kwa isostatic kukanikiza sintering, pamakhala kutentha kwambiri komanso kuthamanga kwa isostatic.

Gasi wogwiritsidwa ntchito pakuwotcha kwa isostatic

Mpweya wa Argon umagwiritsidwa ntchito pa kutentha kwa isostatic kukanikiza sintering. Mu ng'anjo ya sintering, pali kutentha kwakukulu komanso kuthamanga kwambiri. Mpweya wa Argon ukhoza kuyambitsa kugwedezeka kwambiri chifukwa cha kuchepa kwamphamvu komanso kukhuthala kwamphamvu, komanso ma coefficients apamwamba akukula kwamafuta. Chifukwa chake, ma coefficients otengera kutentha kwa makina otentha a isostatic ndi apamwamba kuposa a ng'anjo yachikhalidwe.

Kugwiritsa ntchito kutentha kwa isostatic pressing sintering

Kupatula popanga zinthu za tungsten carbide, palinso ntchito zina za kutentha kwa isostatic pressing sintering.

1. Pressure sintering of power.

Mwachitsanzo. Ti aloyi amapangidwa ndi otentha isostatic kukanikiza sintering kupanga mbali ya ndege.

2. Kumangirira kwamitundu yosiyanasiyana yazinthu.

Mwachitsanzo. Zophatikiza zamafuta a nyukiliya zimapangidwa ndi hot isostatic pressing sintering kuti zigwiritsidwe ntchito mu zida zanyukiliya.

3. Kuchotsa pores otsalira mu zinthu sintered.

Mwachitsanzo. Tungsten carbide ndi zinthu zina, monga Al203, amapangidwa ndi otentha isostatic kukanikiza sintering kupeza katundu mkulu, monga kuuma mkulu.

4. Kuchotsa zolakwika zamkati za castings.

Al ndi superalloys amapangidwa ndi kutentha kwa isostatic kukanikiza sintering kuchotsa zolakwika zamkati.

5. Rejuvenation wa mbali kuonongeka ndi kutopa kapena zokwawa.

6. High-pressure impregnated carbonization njira.

Zida zosiyanasiyana zopangira pamoto wotentha wa isostatic

Popeza kutentha kwa isostatic pressing sintering kuli ndi ntchito zambiri, kumatha kugwiritsidwa ntchito kupanga mitundu yazinthu. Zida zosiyanasiyana zimakhala ndi mawonekedwe osiyana a thupi ndi mankhwala, kotero zimakhala ndi zofunikira zosiyana pazochitika za sintering. Tiyenera kusintha kutentha ndi kupanikizika kwa zipangizo zosiyanasiyana. Mwachitsanzo, Al2O3 imafuna 1,350 mpaka 1,450°C ndi 100MPa, ndipo Cu alloy imapempha 500 mpaka 900°C ndi 100MPa.

Ngati muli ndi chidwi ndi zinthu za tungsten carbide ndipo mukufuna zambiri ndi zambiri, mutha KULUMIKIZANA NAFE pa lamya kapena makalata kumanzere, kapena TITUMIZANI MAIME pansi pa tsamba.
