Impembelelo yokulawulwa komxholo wekhabhoni ye-carbide kumgangatho

Umxholo wekhabhoni kwiyenziwe ngesamentecarbide yafundwa ucula ivacuum sintering method.Uhlalutyo lubonise ukuba umxholo wekhabhoni opheleleyo kwizinto eziluhlaza zidlala indima ecacileyo kumxholo wekhabhoni we-alloy.Ukongezelela, iinqununu ezinzima kwi-powder ecinezelweyo zenziwe ngexesha loxinzelelo.

Akulula ukukhubaza kunye nokutyumza ngexesha lenkqubo, kwaye kulula ukuyibhula, okukhokelela ekubunjweni kwemingxuma etywiniweyo ngexesha lenkqubo ye-liquid sintering, enempembelelo enkulu kumxholo wekhabhonitungsten carbide ingxubevange, ngelixa inani leglue elongezelelweyo linempembelelo encinci kumxholo wekhabhonii-carbide enesamente..Njengoko ukushisa kwe-sintering kukhula ukusuka kwi-1400 ° C ukuya kwi-1480 ° C, umxholo wekhabhoni kwi-alloy uqala ukwanda kwaye emva koko uyancipha.Xa ukushisa kwe-sintering ku-1450 ° C, umxholo wekhabhoni ufikelela kwinqanaba eliphezulu.

Amagama angundoqo: i-carbide enesamente;pressing: sintering.Kwinkqubo yemveliso yei-carbide enesamente, umxholo wekhabhoni unempembelelo ebaluleke kakhulu kwi-WC ubungakanani bengqolowa, isakhiwo sesigaba kunye neempawu zemishini ye-carbide ene-cemented, kunye nomxholo wekhabhoni kwizinto eziluhlaza, Ubungakanani beglue ebongeziweyo, ukucinezela, kunye ne-sintering konke kuya kuchaphazela umxholo wekhabhoni.Abaphengululi basekhaya nakwamanye amazwe baye benza uphando olungakumbi malunga nobudlelwane phakathi komxholo wekhabhoni kunye namandla okuguquguquka, ubunzima kunye nokunyanzeliswa kwamandla, kodwa ngaphantsi kwezinto ezichaphazela umxholo wekhabhoni.Eli nqaku lisebenzisa indlela ye-vacuum sintering ukufunda umxholo wekhabhoni kwizinto eziluhlaza., impembelelo yokudibanisa iglue, ukucinezela kunye neenkqubo ze-sintering kumxholo wekhabhoni
