High dhau ib tug toughness sintering kub nyob rau saum npoo ntawmtitanium phajyuav ua kom qhov tsim ceev ntawm titanium carbide nplej. Qhov kawg sintering kub ntawm titanium carbide siab manganese steel sib raug zoo cemented carbide feem ntau yog 1420 ℃. Qhov kub siab sintering yuav tsum tsis txhob siab dhau, yog li theem tsevneeg dhau los ua kua theem thiab cov hlau ploj, yog li cov theem nyuaj tau nyob ib sab thiab sib xyaws los ua ib qhov chaw ntawm tawg.
Ntawm chav kawm, qhov kub siab sintering yuav tsum tsis txhob dhau heev, txwv tsis pub lub alloy yuav qis dua. Ntxiv rau qhov tau hais tseg yuav tsum tswj cov kub sintering thiab nrawm, lub tshuab nqus tsev hauv lub tshuab ua kom nkag mus ua kua theem sintering theem. Nws tseem yog qhov tsim nyog los tswj lub nqus qib hauv qhov cub tawg thaum lub sijhawm ua haujlwm txhaum. Vim tias dhau los ntawm lub tshuab nqus tsev kawm ntawv qib siab ntau, ntau ntawm cov theem ua kua hlau yuav volatilize, sib sau cov kev sib cais. Tshwj xeeb tshaj yog nyob rau hauv peb theem ntawm kev puas tsuaj, rov qab thiab ua kua theem sintering, qhov cua sov thaum lub sij hawm sintering tsis haum rau xws li alloys.
Qhov saum npoo thiab sab hauv tawv ntawm titanium phaj yuav tsum nruj me ntsis ntawm cov nqi cua sov thiab tuav lub sijhawm. Vim tias nyob hauv qis-kub degumming theem, qhov kev cog lus tso zis compression kev nyuaj siab thiab cov neeg ua hauj lwm sib tw volatilizes. Yog tias cov cua kub ceev nrawm, tus neeg sawv cev tiv thaiv kab lig dhau mus rau volatilize thiab dhau los ua zog tom qab liquefaction, ua rau kev cog lus tawg lossis tawg;
Nws yog qhov tsim nyog kom muaj sijhawm txaus rau kev cog xoob kom tshem tawm cov volatiles thiab oxygen hauv cov hmoov nyoos hmoov (xws li Mn2Fe master alloy); thaum nkag mus rau theem ua kua sintering theem, qhov cua sov yuav tsum tau ua kom qeeb mus rau tag nrho cov ua haujlwm tsis txaus ntseeg. Lub ntsiab lus sintering ntawm steel-sib raug zoo cemented carbide yog lub hauv paus ntsiab lus ntub dej, tso cai rau cov theem ua kua kom ntub cov theem ntawm cov theem nyuaj (theem nyuaj), txwv tsis pub cov kua theem hlau FeMn yuav ua rau qhov chaw ntawm lub pob zeb thiab txawm ploj.
