Lub Versatility Ntawm Tungsten Carbide Tshuab Riam Yuav Pib Stronger Thiab Stronger
Khoom siv yog qhov khoom siv rau kev tsim kho ntawm tib neeg thiab ib qho ntawm kev tshwm sim ntawm kev sib raug zoo. Ib cov khoom sib xyaw uas ua los ntawm cov theem nyuaj ntawm cov hlau thiab cov hlau txuas ntawm lub tshuab hlau metallurgy. Nws yog dav siv nyob rau hauv niaj hnub manufacturing industries rau nws zoo tshaj plaws kev ua tau zoo, thiab yog hu ua "industrial hniav". , originated nyob rau hauv lub xyoo pua puv 19 thiab. Thiab nws ' s tam sim no lug siv hauv tshuab riam.
Nrog lub ntiaj teb ntawm kev lag luam thiab kev nce qib ntawm kev tshawb fawb thiab kev siv tshuab, kev siv cemented carbide cov khoom yog ua neeg xav tau ntau dua. Kev tsim cov cuab yeej tsim tawm ntawm kev lag luam hauv cemented carbide tseem ceev nrooj, tshwj xeeb tshaj yog rau cemented carbide tuam carbide inserts.
Qhov tseeb cemented carbide tshuab clamping cuab tam siv ib tug siab hybrid siab-cobalt (13%) ultra-fine grain loj matrix nrog ib tug nyuaj theem grain ntawm 0.2 + 0.5 + 0.8μm, uas ua rau lub zog thiab hardness ntawm lub hauv paus pib cov khoom Significantly kho, nrog rau geometry thiab clamping ntawm lub ntsej muag cov hniav nyob ze ntawm lub zog ntawm lub qhov me ntsis thiab cov cim tho taub tsim thiab kev ua haujlwm siab titanium nitride thiab titanium aluminide nanophysical coatings, uas qhia tau zoo heev Kev ua tau zoo.
Ib qho ultra-fine grain gradient cemented carbide substrate siv nrog lub nruab nrab kub tshuaj ntawm titanium oxynitride thiab ib nplua-grained columnar a-Al2O3 tshuaj txheej. Cov nplaum yog kho nrog txoj kev kho tom qab uas tshem tawm cov kev nyuab siab, piv txwv li, los ntawm kev txhaj tshuaj. Tensile kev nyuaj siab ntawm CVD lo rau ntawm lub ntsej muag lub ntsej muag txo lub ntsej muag ntawm lub ntsej muag ntawm Al2O3 ntawm 40% thiab cov kev nyuaj siab ntawm lub txheej txheej ntawm 20%, uas ua rau cov kev lag luam tawm me me thiab ua kom tawv nqaij ntawm cov hniav . Hniav qhov koob meej thiab kev ntseeg tau zoo tuaj yeem ua kom tiav qhov txheej txheem ntawm lub txheej thiab txo qhov nyiaj ntawm lub ntxig thiab lub nti.
Qhov sib ntxiv ntawm me me ntawm cov ntsiab lus rau lub cemented carbide txhawb zog ntawm cov khoom tawv, nyom ntawm cov khoom, lim qhov ciam av loj thiab ho ua rau lub zog ntawm cov ntaub ntawv yooj yim thiab cov teeb meem ntawm cov khoom. Ultrafine grained cemented carbide thiab nanostructured coatings tau los ua lub hauv paus qauv. Tam sim no, txoj kev siv tshuab cemented carbide cuab yeej tsim tawm hauv ob yam lus qhia. Ntawm qhov one hand, cov khoom siv dav dav yog ntau thiab ntau dua thiab muaj ntau yam. Ntawm qhov tod tes, cov ntaub ntawv tshwj xeeb muaj ntau thiab ntau dua, thiab tsim nyog rau cov ntaub ntawv yuav tsum tau ua tiav thiab txiav tej yam kev mob, uas yog ua kom lub hom phiaj ntawm kev txhim kho cov kev ua tiav.
