Kub Isostatic Pressing (HIP) yog dab tsi?

Thaum peb tab tom tsim cov khoom lag luam tungsten carbide, peb yuav tsum xaiv cov khoom siv zoo tshaj plaws, tungsten carbide hmoov thiab binder hmoov, feem ntau yog cobalt hmoov. Sib tov thiab milling lawv, ziab, nias, thiab sintering. Thaum lub sij hawm sintering, peb ib txwm muaj kev xaiv sib txawv. Thiab nyob rau hauv tsab xov xwm no, peb yuav tham txog kub isostatic nias sintering.

Kub Isostatic Pressing yog dab tsi?

Kub Isostatic Pressing, tseem hu ua HIP, yog ib txoj hauv kev ua cov khoom siv. Thaum kub isostatic nias sintering, muaj qhov kub thiab txias isostatic siab.

Gas siv nyob rau hauv kub isostatic nias sintering

Argon roj yog siv nyob rau hauv kub isostatic nias sintering. Hauv qhov cub sintering, muaj qhov kub thiab txias. Argon roj yuav ua rau khaus convection vim tsawg ntom thiab coefficient ntawm viscosity, thiab siab coefficients ntawm thermal expansion. Yog li ntawd, lub tshav kub hloov coefficients ntawm kub isostatic pressing khoom yog siab dua li ntawm cov tsoos rauv.

Daim ntawv thov ntawm kub isostatic nias sintering

Tsuas yog rau kev tsim khoom tungsten carbide, muaj lwm yam kev siv ntawm kub isostatic nias sintering.

1. Siab sintering ntawm lub hwj chim.

Piv txwv. Ti alloys yog tsim los ntawm kub isostatic nias sintering los ua ib feem ntawm lub dav hlau.

2. Diffusion bonding ntawm ntau hom khoom.

Piv txwv. Nuclear roj sib sau ua ke yog tsim los ntawm kub isostatic nias sintering siv rau hauv nuclear reactors.

3. Kev tshem tawm cov pores seem hauv cov khoom sintered.

Piv txwv. Tungsten carbide thiab lwm yam ntaub ntawv, xws li Al203, yog tsim los ntawm kub isostatic nias sintering kom tau txais cov khoom siab, zoo li siab hardness.

4. Kev tshem tawm sab hauv qhov tsis xws luag ntawm castings.

Al thiab superalloys yog tsim los ntawm kub isostatic nias sintering kom tshem tawm cov teeb meem sab hauv.

5. Rejuvenation ntawm qhov chaw puas los ntawm qaug zog los yog creep.

6. High-pressure impregnated carbonization txoj kev.

Cov ntaub ntawv sib txawv los tsim cov kub isostatic nias

Txij li thaum kub isostatic nias sintering muaj ntau daim ntawv thov, nws tuaj yeem siv los tsim cov khoom siv. Cov ntaub ntawv sib txawv muaj cov yam ntxwv ntawm lub cev thiab tshuaj lom neeg sib txawv, yog li lawv muaj cov kev cai sib txawv rau sintering. Peb yuav tsum hloov qhov kub thiab siab ntawm cov khoom sib txawv. Piv txwv li, Al2O3 xav tau 1,350 txog 1,450°C thiab 100MPa, thiab Cu alloy nug txog 500 txog 900°C thiab 100MPa.

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.
