Patinenge tichigadzira tungsten carbide zvigadzirwa, isu tinofanira kusarudza yakanakisa mbishi, tungsten carbide poda uye binder poda, kazhinji cobalt hupfu. Sanganisa uye zvigayo, kuomesa, kudzvanya, uye kunyura. Panguva yekuridza, isu tinogara tine sarudzo dzakasiyana. Uye mune ino chinyorwa, isu tichataura nezve inopisa isostatic kudzvanya sintering.

 

Chii chinonzi Hot Isostatic Pressing?

Kupisa Isostatic Pressing, inozivikanwawo seHIP, ndiyo imwe yenzira dzekugadzirisa zvinhu. Munguva yekupisa isostatic kudzvanya sintering, kune yakanyanya tembiricha uye isostatic pressure.

 

Gasi rinoshandiswa mukupisa isostatic kudzvanya sintering

Argon gasi rinoshandiswa mukupisa isostatic kudzvanya sintering. Muchoto chekupisa, kune kutonhora kwakanyanya uye kudzvinyirira kwakanyanya. Argon gasi ingangokonzera convection yakanyanya nekuda kwekushomeka kwakadzika uye coefficient ye viscosity, uye yakakwirira coefficients yekuwedzera kupisa. Naizvozvo, iwo kupisa kwekutamisa coefficients yeanopisa isostatic yekutsikirira michina yakakwira kupfuura iyo yevira yechinyakare.

 

Kushandiswa kwekupisa isostatic kudzvanya sintering

Kunze kwekugadzira tungsten carbide zvigadzirwa, kune zvimwe zvinoshandiswa zvekupisa isostatic kudzvanya sintering.

1. Dzvinyiriro sintering simba.

Eg. Ti alloys anogadzirwa nekupisa isostatic kudzvanya sintering kuita chikamu chendege.

2. Diffusion bonding yemhando dzakasiyana dzezvinhu.

Eg. Magungano emafuta enyukireya anogadzirwa nekupisa isostatic pressing sintering kuti ishandiswe mumareactor enyukireya.

3. Kubviswa kwemapores akasara muzvinhu zvakasvibiswa.

Eg. Tungsten carbide uye zvimwe zvinhu, zvakaita seAl203, zvinogadzirwa nekupisa isostatic kudzvanya sintering kuti uwane yakakwirira zvivakwa, senge kuomarara kwakanyanya.

4. Kubviswa kwehurema hwemukati hwekukanda.

Al uye superalloys inogadzirwa nekupisa isostatic kudzvanya sintering kubvisa hurema hwemukati.

5. Kuvandudzwa kwezvikamu zvakakuvadzwa nekuneta kana kukambaira.

6. High-pressure impregnated carbonization nzira.

 

Zvinhu zvakasiyana zvekugadzira mune inopisa isostatic kudzvanya

Sezvo inopisa isostatic kudzvanya sintering ine akawanda maapplication, inogona kushandiswa kugadzira marudzi ezvigadzirwa. Zvishandiso zvakasiyana zvine hunhu hwakasiyana hwemuviri uye makemikari, saka zvine zvakasiyana zvinodiwa zvesintering mamiriro. Tinofanira kushandura kutonhora uye kudzvinyirira kwezvinhu zvakasiyana-siyana. Semuenzaniso, Al2O3 inoda 1,350 kusvika 1,450°C uye 100MPa, uye Cu alloy inobvunza 500 kusvika 900°C uye 100MPa.
