Titanium zirconium molybdenum pas nrig (TZM qws) yog npaj los ntawm hmoov metallurgy. TZM bar yog ib hom superalloy uas yog ua los ntawm molybdenum raws li matrix thiab ntxiv nrog cov kab lus xws li Ti, Zr, thiab C. Nws muaj cov khoom kub kub zoo, cov khoom siv kho tshuab, thiab lwm yam khoom zoo, nrog rau cov ntsiab lus siab melting, siab zog, siab elastic modulus, me me linear expansion coefficient, tsis tshua muaj vapor siab, zoo conductivity, thiab thermal conductivity, muaj zog corrosion kuj, zoo high-temperature mechanical zog, yog li nws yog dav siv nyob rau hauv ntau lub teb.
Classification of TZM bars
TZM alloy tuav tau muab faib ua hom hauv qab no raws li qib ntawm kev ua:
Sintered TZM tuav: Sintered TZM tuav yog cov tuav uas tsis tau ua tiav tom qab, thiab lawv qhov chaw yog grey thiab dub yam tsis muaj hlau nplaum.
Forged TZM bar: tom qab forging, saum npoo ntawm TZM bar yuav muaj txheej txheej oxide, thiab saum npoo yuav pom cov xim tsis muaj xim dub.
Polish TZM pas nrig: TZM pas nrig tuaj yeem polished ib zaug lossis ob peb zaug raws li lub xeev saum npoo thiab cov kev xav tau zoo, thiab polished nto ntawm TZM pas nrig qhia cov nyiaj-grey metallic luster.
Polishing TZM pas nrig: Polishing TZM pas nrig yog hais txog polishing tus pas nrig kom txo tau qhov roughness ntawm cov pas nrig, thiaj li yuav tau txais ib tug ci thiab tiaj tus TZM pas nrig.
Alkali-ntxuav TZM pas nrig: Lub alkali-ntxuav TZM pas nrig yog tau los ntawm cov txheej txheem ntxuav alkali. Qhov saum npoo ntawm cov alkali-ntxuav TZM pas nrig qhia tau hais tias grey metallic luster thiab yog tus du.
TZM rod application
TZM tuav muaj cov khoom kub kub zoo thiab cov khoom siv kho tshuab, yog li lawv tau siv dav hauv ntau qhov chaw kub kub. Nws feem ntau yog siv los tsim cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob thiab tsim nyog rau kev npaj cov ion implantation qhov chaw. Raws li cov khoom siv hluav taws xob kub kub thiab cov txheej txheem kub kub, nws feem ntau yog siv los ua cov khoom siv hluav taws xob hauv cov iav thiab cov khoom siv hluav taws xob refractory ua lub cub tawg. Ua haujlwm hauv 1300 degree iav yaj, nws tsis tsuas yog muaj kev ua haujlwm zoo tab sis kuj muaj lub neej ua haujlwm ntev. Nws kuj yog siv dav hauv electrode hauv kev lag luam tsawg hauv ntiaj teb. Txhawm rau npaj ntau hom kub nozzles thiab kub khiav, TZM rods kuj tuaj yeem ua haujlwm hauv cov tshuab kub khiav.
