Carbide iyo diyaarinta cermet

Alaabooyinka adag ee WC-Co waxay leeyihiin laqabsiga mikrowave wanaagsan.Inta lagu guda jiro nidaamka sintering, hababka khasaaraha ka shaqeeya aagga heerkulka hoose yihiin inta badan polarization luminta nasinta iyo luminta magnetka, halka aagga heerkulka sare Alloy nuugaya tamarta microwave.Inta badan qaab lumis dielectric iyo luminta conductivity.

Thedaawahaiyada oo lagu daro 0.4% VC iyo 0.2% Cr3C2 (jajab tiro badan) sida qalabka caawiye ayaa leh waxqabadka ugu fiican;Isticmaalka vacuum microwave sintering si weyn u hagaajinaysaa waxqabadka ee daawaha.Isticmaalka foornada mikrowave-ka-badanWC-8Co, waxaa lagu daraa 1400 ° C iyada oo aan la ilaalin kulaylka.Cufnaanta waxay gaari kartaa 14.71g/cm,HRA ayaa gaadhay90.3, dhismuhuna waa lebbis.

Farsamaynta mikrowave-ka waxaa loo isticmaali karaa in lagu diyaariyo shahaado aad u fiican oo leh miro wanaagsan, qaab dhismeed lebis ah iyo waxqabad aad u wanaagsan.Marka heerkulku kordho, hoos u dhaca, cufnaanta, xoogga dabacsanaanta iyo qallafsanaanta shahaado aadka u fiican ayaa marka hore kordha ka dibna hoos u dhaca, iyadoo qiimaha ugu sarreeya uu ka muuqdo 1500 ° C;Habka ku habboon mikrowayt-ka ee cermets ultra-fine Ka dib markii lagu hayo 1500 ° C 30 daqiiqo, xoogga dabacsanaanta iyo qiyamka qallafsanaantu waa 1547MPa iyo 90.6HRA siday u kala horreeyaan, kuwaas oo la kordhiyey 24.0% iyo 0.7% siday u kala horreeyaan marka loo eego sintering caadiga ah.
