Umthelela wokulawula okuqukethwe kwekhabhoni ye-carbide esimende kukhwalithi

Okuqukethwe kwekhabhoni kukukasimendei-carbide yafundwa ucula indlela ye-vacuum sintering.Ukuhlaziywa kuveze ukuthi ingqikithi yekhabhoni equkethwe ezintweni ezingavuthiwe idlala indima ebalulekile kokuqukethwe kwekhabhoni yealloy.Ngaphezu kwalokho, izinhlayiya ezinzima ku-powder ecindezelwe zakhiwa ngesikhathi sokucindezela.

Akulula ukukhubaza nokuchoboza ngesikhathi senqubo, futhi kulula ukuvala ibhuloho, okuholela ekwakhekeni kwezimbobo ezivaliwe ngesikhathi senqubo ye-liquid sintering, enomthelela omkhulu ekuqukethwe kwekhabhoniingxube ye-tungsten carbide, kuyilapho inani leglue elingeziwe linomthelela omncane kokuqukethwe kwekhabhoni yei-carbide enosimende..Njengoba izinga lokushisa le-sintering likhuphuka lisuka ku-1400°C liye ku-1480°C, okuqukethwe kwekhabhoni ku-alloy kuqala kuyanda bese kuncipha.Uma izinga lokushisa le-sintering lingu-1450°C, okuqukethwe kwekhabhoni kufinyelela ezingeni eliphezulu.

Amagama angukhiye: i-carbide enosimende;pressing: sintering.Enqubweni yokukhiqiza yei-carbide enosimende, okuqukethwe kwekhabhoni kunomthelela obaluleke kakhulu kusayizi wokusanhlamvu we-WC, ukwakheka kwesigaba kanye nezakhiwo zemishini ze-carbide enosimende, kanye nokuqukethwe kwekhabhoni endaweni eluhlaza, Inani leglue elengeziwe, ukucindezela, kanye ne-sintering konke kuzothinta okuqukethwe kwekhabhoni.Izazi ekhaya naphesheya zenze ucwaningo olwengeziwe mayelana nobudlelwano phakathi kokuqukethwe kwekhabhoni namandla aguqukayo, ubulukhuni namandla okuphoqa, kodwa kancane ezintweni ezithinta okuqukethwe kwekhabhoni.Lesi sihloko sisebenzisa indlela ye-vacuum sintering ukufunda okuqukethwe kwekhabhoni ezintweni zokusetshenziswa., umthelela wokuhlanganisa iglue, ukucindezela kanye nezinqubo ze-sintering kokuqukethwe kwekhabhoni
