Inkambu: Metallurgy.
Into: Ukusungula kuhlobene ne-Powter Metallurgy Field. Ikakhulu kuhlobana nokwamukela i-alloy eqinile eyenziwe ngesisekelo se-tungsten carbide. Ingasetshenziselwa ukwenziwa kwama-cutter, ukushayela kanye nokugaya kokugaya. I-hard alloy iqukethe ama-80.0-82.0 wt% tungsten carbide kanye ne-18.0- 20.0 wt% yokubopha. Ukubopha kuqukethe, WT%: Molybdenum 48.0-50.0; niobium 1.0-2.0; I-Rhenium 10.0-12.0; cobalt 36.0-41.0.
Umphumela: Ukwemukelwa kwe-alloy enamandla aphezulu.
Ukufanisa
Ukusungulwa kuhlobene nomkhakha we-powder metallurgy kanye nokukhiqizwa kwama-alloys anzima asuselwa eTungsten Carbide, angasetshenziselwa ukwenziwa kwama-cutters, ama-drill, amamilila namanye amathuluzi.
I-Carbide eyaziwayo esuselwa eTungsten Carbide, equkethe i-3,0 kuya ku-20.0 wt.% I-allOy equkethe, wt.% molybdenum - kufika ku-5.0; I-Niobium - Kufika ku-3.0 [1].
Inhloso yokusungula ukwandisa amandla we-alloy.
Umphumela wezobuchwepheshe utholakala kulokho e-Alloy eqinile esuselwa eTungsten Carbide equkethe i-80.0-82.0 wt.% I-Carbide, i-BT.%: niobium 1.0-2.0, Rhenium 10.0-12.0; cobalt 36.0-41.0.
Etafuleni. 1 ikhombisa ukwakheka kwe-alloy, kanye namandla okugcina ekugobeni. Etafuleni. 2 kukhombisa ukwakheka kwe-ligament.
Ithebula 1 Izakhi zokwakheka, i-WT.%: I-One 2 3 Wolfram Carbide 80.0 81.0 82.0 Bunch 20.0 19.0 18.0 18.0 1950 ~ 1950
Ithebula 2
Ama-powders wezakhi ze-alloy axutshwe ngokulingana okukhonjisiwe, ingxube icindezelwa ngaphansi kwengcindezi ka-4.5-4.8 t / cm 2 futhi isono esithandweni sikagesi endaweni yokushisa amahora angama-7-9. Ngenkathi esona, isigaxa sincibilikisa ingxenye ye-tungsten carbide futhi incibilike. Umphumela uba yinto ebuyisile eyakha isakhiwo sayo siqukethe izinhlayiya ze-tungsten Carbide ezixhunywe nge-binder.
