I-carbide enosimende yenziwe ngobulukhuni obuphakeme, i-refractory metal carbide (njenge-WC, i-TiC, i-TaC, i-NbC, njll.) kanye nezibophezelo zensimbi (njenge-cobalt, i-nickel, njll.) ngenqubo ye-powder metallurgy, okwamanje ingamandla aphakeme kakhulu emhlabeni. ingxubevange, enobulukhuni obuphezulu (89 ~ 93Hm), amandla aphezulu, ubulukhuni obuhle bokushisa nezinye izici.Ngakho-ke, isetshenziswa kabanzi ekwenzeni izingcezu zokuhlola, isikhunta namathuluzi.Ngokuthuthukiswa okuqhubekayo kobuchwepheshe bokusika ekuqondeni kwejubane eliphezulu nokunemba okuphezulu, ubulukhuni, ukumelana nokugqoka, ukunemba kokugaya kanye nekhwalithi yokusika yamathuluzi e-carbide e-cemented kuyadingeka ukuthi ibe phezulu nangaphezulu.Usayizi wokusanhlamvu we-carbide enosimende nawo uthuthuke kancane kancane kusukela kokusanhlamvu okumahhadlahhadla kanye nokusanhlamvu okuphakathi kuya kokusanhlamvu okucolisekile, okusanhlamvu okuphakeme kakhulu kanye ne-nanocrystal-grained.
Njengamanje, i-carbide enosimende eqinile isetshenziswa kabanzi kumathuluzi e-geological kanye namaminerali, isitembu siyafa, ukubhola uwoyela, izando ezinkulu eziphezulu zokukhiqiza idayimane lokwenziwa, izingxenye zenjini yejethi neminye imikhakha;i-carbide enosimende enohlamvu oluhle kakhulu kanye ne-ultra-fine-grained cemented inezici zokuqina okuphezulu namandla aphezulu, isetshenziselwa ikakhulukazi ukwakhiwa kwamathuluzi e-carbide aqinile, ukufaka okunenkomba kanye nama-micro drill.
Ngokucwengisiswa kwezinhlamvu ze-WC ku-carbide enosimende, izici zemishini ezinjengokuqina namandla ziye zanda, okwamanje izakhiwo ezinjengokuqina kokuphuka kwehle, nokusebenza kokugaya okunjengokumelana nokugqokwa nakho kwashintsha.
Amasondo amathathu ahlukene okusanhlamvu okusanhlamvu okugaya ibhondi yebhondi yedayimane asetshenziselwa ukwenza izivivinyo zokugaya ngaphansi kwezimo ezithile zokugaya ama-carbide amathathu kasimende anosayizi abahlukene wokusanhlamvu: amaholoholo, amahle kanye ne-ultra-fine.Ngokukalwa kwamandla okuphotha, isondo lokugaya nokulahlekelwa kwengcezu yokusebenza, kanye nobulukhuni bomshini bomshini wokugaya ngesikhathi senqubo yokugaya, umthelela wokushintsha usayizi wokusanhlamvu we-WC ku-carbide enosimende ekusebenzeni nasekusebenzeni okufana namandla okugaya, isilinganiso sokugaya, kanye nobulukhuni bobuso buyahlaziywa.
Ngokuhlolwa, kungaziwa ukuthi ngaphansi kwesimo, imingcele yokugaya ye-surface grinder iyafana, amandla okugaya kanye namandla okugaya asetshenziswa ukugaya i-carbide enosimende eqinile inkulu kunaleyo ye-fine-grained ne-ultra-fine. -i-grained, futhi amandla okugaya e-surface grinder ayanda ngokukhuphuka kosayizi wokusanhlamvu.Isilinganiso sokugaya se-ultra-fine cemented carbide siyakhula ngokukhula kosayizi wokusanhlamvu, okubonisa ukuthi ukumelana nokugqokwa kwalolu hlobo lwe-carbide kasimende kuncipha ngokukhula kosayizi wokusanhlamvu, kanye nokuhwaqamuka kwalolu hlobo lwe-carbide enosimende ngemva kokugaya kahle ngaphansi. izimo ezifanayo zokugaya ziyancipha ngokukhula kosayizi wokusanhlamvu.
Ukusebenzisa isondo lokugaya idayimane kuyindlela eyinhloko yokukhiqiza amathuluzi e-carbide enosimende, ukuhwaqeka kwendawo yokugaya kunomthelela obalulekile ekusebenzeni kokusika kanye nempilo yesevisi yamathuluzi e-carbide enosimende, futhi imingcele yokugaya yizici eziyinhloko ezithinte ukuhwaqeka komhlaba. i-carbide enosimende
I-WC-Co cemented carbide specimen yahlolwa ukugaya emshinini wokugaya ongaphezulu, futhi isifanekiso kwakuyi-ultra-fine-grained cemented carbide esintered by HIP technology.
Ngokujula okufanayo, ukuhwalala kwendawo yokugaya yesampula kwanda ngokukhuphuka kosayizi wezinhlayiyana zesondo lokugaya.Uma kuqhathaniswa nesondo lokugaya elingu-150#, ukuhwalala kwangaphezulu kwesampula kokugaya kuyahluka kancane uma ugaya ngesondo lokugaya elingu-280#, kanti ukuhwaqaza kushintsha kakhulu uma ugaya ngesondo lokugaya i-W20.
