Yintoni iHot Isostatic Pressing (HIP)?

Xa sisenza iimveliso ze-tungsten carbide, kufuneka sikhethe eyona nto ingcono kakhulu, i-tungsten carbide powder kunye ne-binder powder, idla ngokuba ngumgubo we-cobalt. Xuba kwaye uzigalele, ukoma, ukucofa, kunye nokutshiza. Ngexesha lokucula, sihlala sinokukhetha okwahlukileyo. Kwaye kweli nqaku, siza kuthetha malunga ne-isostatic pressing sintering eshushu.

Yintoni iHot Isostatic Pressing?

I-Hot Isostatic Pressing, eyaziwa ngokuba yi-HIP, yenye yeendlela zokulungisa izinto. Ngexesha elishushu le-isostatic sintering, kukho amaqondo obushushu aphezulu kunye noxinzelelo lwe-isostatic.

Irhasi esetyenziswa kwi-isostatic pressing sintering eshushu

Irhasi yeArgon isetyenziswa kwi-isostatic pressing sintering eshushu. Kwisithando somlilo, kukho ukushisa okuphezulu kunye noxinzelelo oluphezulu. Irhasi yeArgon kusenokwenzeka ukuba ibangele ukuhanjiswa okukhulu ngenxa yokuxinana okuphantsi kunye ne-coefficient of viscosity, kunye ne-coefficients ephezulu yokwandiswa kwe-thermal. Ke ngoko, i-coefficients yokuhambisa ubushushu yezixhobo ezishushu ze-isostatic ziphezulu kunezo ziko lemveli.

Ukusetyenziswa kwe-isostatic eshushu yokucofa sintering

Ngaphandle kokwenziwa kweemveliso ze-tungsten carbide, kukho ezinye izicelo ze-isostatic pressing sintering eshushu.

1. Uxinzelelo loxinzelelo lwamandla.

Umz. Ii-alloys ze-Ti zenziwe ngokucinezela kwe-isostatic eshushu ukwenza inxalenye yenqwelomoya.

2. Ukudibanisa ukudibanisa kweentlobo ezahlukeneyo zezinto.

Umz. Iiassemblies zamafutha eNyukliya zenziwa ngokucinezela i-isostatic sintering ukuze zisetyenziswe kwizixhobo zenyukliya.

3. Ukususwa kwee-pores ezishiyekileyo kwizinto ezine-sintered.

Umz. I-tungsten carbide kunye nezinye izinto, ezinje nge-Al203, zenziwe ngokucinezela isostatic sintering ukufumana iipropathi eziphezulu, njengobunzima obuphezulu.

4. Ukususwa kweziphene zangaphakathi zokuphosa.

I-al kunye ne-superalloys zenziwe ngokucinezela isostatic ngokucinezela i-sintering ukususa iziphene zangaphakathi.

5. Ukuhlaziywa kweengxenye ezonakaliswe kukudinwa okanye ukukhasa.

6. Iindlela ze-carbonization ezifakwe kwi-high-pressure.

Izinto ezahlukeneyo zokwenza ngokucinezela isostatic eshushu

Kuba i-isostatic eshushu yokucinezela i-sintering inezicelo ezininzi, inokusetyenziselwa ukwenza iintlobo zemathiriyeli. Izinto ezahlukeneyo zineempawu ezahlukeneyo zomzimba kunye neekhemikhali, ngoko ke zineemfuno ezahlukeneyo zeemeko ze-sintering. Kufuneka sitshintshe ubushushu kunye noxinzelelo lwezixhobo ezahlukeneyo. Umzekelo, i-Al2O3 ifuna i-1,350 ukuya kwi-1,450°C kunye ne-100MPa, kunye ne-Cu alloy icela i-500 ukuya kwi-900°C kunye ne-100MPa.

Ukuba unomdla kwiimveliso ze-tungsten carbide kwaye ufuna ulwazi oluthe kratya kunye neenkcukacha, ungaQHAGAMSHELANA NATHI ngefowuni okanye ngeposi ekhohlo, okanye SITHUMELE MAIL emazantsi ephepha.
