Soo Koobidda Fulinta
Daraasad kiis oo casri ah oo ku saabsan foornada bakhtiinta gaaska ee Jarmalka ee cadaadiska sare leh (1350°C / 20bar): Tamarta VET waxay isticmaashay boolal isku dhafan oo C/C ah, qaab-dhismeedyo culeys fudud leh, iyo ulaha kululaynta garaafka ee CVD SiC-da lagu dahaadhay si loogu beddelo qaybaha dhaqameed ee molybdenum iyo graphite-ka culus. Tani waxay si buuxda u xallisay hoos u dhaca heerkulka sare ee gariirka iyo cilladaha soo noqnoqda ee jabitaanka. Waxqabadka la cabbiray: miisaanka qaab-dhismeedka ayaa hoos u dhacay 62%, awoodda rarka saafiga ah ayaa korodhay 35%, isticmaalka tamarta hal-dufcadood ah ayaa hoos u dhacay 22%, cimriga adeegga qaybaha oo la kordhiyay in ka badan 3 jeer, iyo keydinta kharashka sanadlaha ah ayaa dhaaftay €22,000.

Hawsha daminta gaaska ee cadaadiska sare leh (HPGQ) iyo sintering heerkulka aadka u sarreeya, waxqabadka kulaylka iyo cufnaanta kulaylka ee qaybaha aagga kulul ee xudunta ayaa si toos ah u go'aamiya wax soo saarka qalabka iyo tayada daminta shaqada. Foornooyinka faakuumka dhaqameed waxay inta badan ku tiirsan yihiin qalabka molybdenum (Mo) ama graphite culus oo ay weheliyaan boolal graphite caadi ah. Wareegga kulaylka daran ee 1200°C–1400°C iyo shoogga daminta gaaska dabaysha sare ee qasabka ah ee 10-20 bar, dejimahan caadiga ah waxay la kulmaan jabka heerkulka sare ee daran, jabka, iyo daadinta oksaydhka.

Xaaladda Codsiga & Dhibcaha Xanuunka Macaamiisha
Ulaha kululaynta graphite ee foornada dab-demiska gaaska faakuumka waxay ku shaqeeyaan 1350°C. Inta lagu jiro marxaladda dab-demiska gaaska ee cadaadiska sare leh, gaaska qabow ee xawaare dhan tobanaan mitir ilbiriqsi kasta si toos ah ayuu ugu dhaqmaa dusha sare ee usha kululaynta, taasoo keenta shoog kulul oo daran iyo cadaadis farsamo. Isla mar ahaantaana, qoyaanka iyo oksijiinta haraaga ah ee ku jirta qolka faakuumka waxay sababaan in graphite qaawan uu oksaydho oo uu soo daato. Tani waxay keentaa iska caabin aad u daran, oo sii xumaanaysa isku-midnimada heerkulka aagga kulul (>±10°C) iyo taasoo keenta adkaanta dab-demiska ee aan isku dheelitirnayn.
