Tsis zoo siv
Teb: metallurgy.
Tshuaj Tiv Thaiv: Kev Tsim Nyog cuam tshuam nrog hmoov metallurgy teb. Tshwj xeeb nws cuam tshuam tau txais ntawm sintereded nyuaj alloy raws lub hauv paus ntawm tungsten carbide. Nws tuaj yeem siv rau kev tsim cov cutters, tho thiab milling cutter. Hard alloy muaj 80.0-82.0 wt% tungsten carbide thiab 18.0-20.0 wt% ntawm khi. Khi muaj, wt%: molybdenum 48.0-50.0; niobium 1.0-2.0; Rhenium 10.0-12.0; cobalt 36.0-41.0.
Cov nyhuv: Tau txais cov high-zog alloy.
Kev piav txog
Cov kev tsim muaj cuam tshuam nrog rau lub teb hmoov metallurgy thiab rau cov khoom siv tau siv rau kev tsim cov cutters, hnyiab, mills thiab lwm yam cuab yeej.
Lub npe paub carbide raws li tungsten carbide, muaj 3..0 wt.% Ib phau ntawv muaj, wt.%: CTALT 20.0-75.0; Molybdenum - Txog li 5.0; niobium - txog 3.0 [1].
Lub hom phiaj ntawm kev tsim muaj yog ua kom lub zog ntawm cov alloy.
Qhov tshwm sim kev ua tiav tau ua tiav nyob rau hauv uas nyob rau hauv ib tug sintered nyuaj alloy raws li tungsten carbide thiab 18.0 uv.%: Molybdenum 48 0-50.0; niobium 1.0-2.0, rhenium 10.0-12.0; cobalt 36.0-41.0.
Nyob rau hauv lub rooj. 1 qhia txog kev sib xyaw ntawm cov alloy, nrog rau lub zog tshaj plaws hauv kev khoov. Nyob rau hauv lub rooj. 2 qhia txog kev sib xyaw ntawm lub ligament.
Cov Lus 1 Cheebtsam, WT.%: Ib qho 2 3 Wolfram Carbide 80.0 8.0 18.10 ~ 1950 ~ 1950
Rooj 2. Cheebtsam muaj pes tsawg leeg, WT.%: Ib 2 3 Molybdenum 48.0 4,5 2.0 Rhenium 10.0 12.0 1.0.5 36.0
Cov hmoov ntawm cov txheej txheem alloy tau sib xyaw ua ke, cov sib tov tau nias hauv qhov kub ntawm 1300-1330 ° C hauv nqus rau 7-9 teev. Thaum lub sij hawm sintering, lub binder dissolves ib feem ntawm tungsten carbide thiab melts. Qhov tshwm sim yog cov khoom siv ntom uas nws cov qauv muaj cov tungsten carbide hais nrog los ntawm ib phau ntawv.
