Inkqubo yeSintering yeTungsten Carbide

Inkqubo ye-sintering yenye yamanyathelo ayimfuneko ekuveliseni iimveliso ze-tungsten carbide. Ngokomyalelo we-sintering, inkqubo ye-sintering inokwahlulwa ibe ngamanqanaba amane asisiseko. Makhe sithethe ngala manyathelo mane ngokweenkcukacha kwaye uya kwazi ngakumbi malunga nenkqubo ye-sintering ye-tungsten carbide.

1. Ukususwa kwe-Agent ye-Forming kunye ne-Burn-In stage

Ngenxa yokunyuka kwamaqondo obushushu, ukufuma, irhasi, kunye notywala obushiyekileyo kwindawo eyomileyo yokutshiza iya kufunxwa ngumgubo okanye iarhente yokubumba ide ijike.

Ukunyuka kwamaqondo obushushu kuya kukhokelela ekubeni ngokuthe ngcembe zenze ukubola okanye ukufunxa. Emva koko i-ejenti yokwenza iya kwandisa umxholo wekhabhoni womzimba we-sintered. Ubuninzi bomxholo wekhabhoni buhluka ngokungafaniyo kwi-arhente yokwenza iinkqubo ezahlukeneyo ze-sintering.

Kwiqondo lokushisa elitshisayo, ukuncitshiswa kwe-hydrogen ye-cobalt kunye ne-tungsten oxide ayiphenduli ngamandla ukuba i-vacuum iyancipha kwaye iyancipha.

Ngokunyuka kweqondo lokushisa kunye ne-annealing, i-powder yoxinzelelo loqhagamshelwano luya kupheliswa ngokuthe ngcembe.

I-powder yensimbi eboshiweyo iqala ukubuyisela kwaye ihlaziye kwakhona. Njengoko ukusasazwa komphezulu kwenzeka, amandla oxinzelelo ayanda. Ubungakanani bebhloko bokuncipha bubuthathaka kwaye bunokucutshungulwa njengeplastiki engenanto.

2. Inqanaba leSintering State eliqinileyo

Umzimba we-sintered uya kwenza isivumelwano ngokucacileyo kwinqanaba eliqinileyo le-sintering. Kweli nqanaba, ukusabela okuqinileyo, ukusasazwa, kunye nokuhamba kweplastiki kuyanda, kwaye umzimba we-sintered uya contracted.

3. Ulwelo Sintering Stage

Nje ukuba umzimba we-sintered ubonakale kwisigaba solwelo, ukushwabana kugqitywe ngokukhawuleza. Emva koko isakhiwo esisisiseko se-alloy siya kubumba phantsi kwenguqu ye-crystalline. Xa ubushushu bufikelela kubushushu be-eutectic, ukunyibilika kweWC kwi-Co kunokufikelela malunga ne-10%. Ngenxa yokunyanzeliswa komphezulu wesigaba se-liquid, i-powder particles ivalwe omnye komnye. Ngoko ke, isigaba se-liquid sizalise ngokuthe ngcembe i-pores kwiincinci. Kwaye ukuxinana kwebhloko kwandisa kakhulu.

4. Inqanaba lokupholisa

Kwinqanaba lokugqibela, iqondo lokushisa liya kuhla kwiqondo lokushisa. Isigaba solwelo siya kuqina njengoko ubushushu buhla. Imilo yokugqibela ye-alloy ilungisiwe. Ngeli nqanaba, i-microstructure kunye nesigaba sokubunjwa kwe-alloy utshintsho kunye neemeko zokupholisa. Ukuze kuphuculwe iipropati zomzimba kunye nezixhobo ze-alloys, olu phawu lwe-alloy lungasetyenziselwa ukutshisa i-carbide ene-cemented.

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