Qhov txawv ntawm titanium anode thiab titanium alloy?
Titanium yog ib qho tseem ceeb ntawm cov hlau tsim nyob rau hauv 1950s. Titanium alloy yog dav siv nyob rau hauv ntau yam teb vim nws lub zog siab, zoo corrosion kuj thiab kub kub kuj. Ntau lub teb chaws hauv ntiaj teb tau paub txog qhov tseem ceeb ntawm titanium alloy cov ntaub ntawv, thiab tau ua raws li kev tshawb fawb thiab kev loj hlob ntawm nws, thiab tau siv rau hauv kev xyaum.
Cov tswv yim titanium alloy yog Ti-6Al-4V alloy tsim tau zoo hauv xyoo 1954 hauv Tebchaws Meskas. Lub titanium anode tau dhau los ua cov ace alloy hauv kev lag luam titanium alloy vim nws qhov kub tsis kam, lub zog, plasticity, toughness, formability, weldability, corrosion kuj thiab biocompatibility. Kev siv alloy tau suav txog 75 feem pua ~ 85 feem pua ntawm tag nrho cov titanium alloys. Ntau lwm cov titanium alloys tuaj yeem suav tias yog Ti-6Al-4V variants. Nyob rau xyoo 1950 txog xyoo 1960, feem ntau yog kev txhim kho kub ntawm titanium alloy rau aeroengine thiab cov qauv titanium alloy rau lub cev, titanium anode nyob rau xyoo 1970 los tsim ntau cov corrosion resistant titanium alloy, txij li xyoo 1980s, corrosion resistant titanium alloy thiab siab zog. titanium alloy tau tsim ntxiv.
Kev siv kub ntawm cov cua sov-resistant titanium alloy tau nce los ntawm 400 degree hauv xyoo 1950 mus rau 600 ~ 650 degree hauv xyoo 1990. Lub A2 (Ti3Al) thiab r (TiAl) lub hauv paus alloys tau ua kom titanium txav los ntawm qhov txias kawg ntawm lub cav ( kiv cua thiab compressor) mus rau qhov kub kawg (turbine) qhov twg lub cav siv. Cov txheej txheem titanium alloys tsim rau cov kev taw qhia ntawm lub zog siab, siab plasticity, siab zog, siab toughness, siab modulus thiab siab siab kam rau ua. Tsis tas li ntawd, txij li xyoo 1970s, cov duab cim xeeb xws li Ti-Ni, Ti-Ni-Fe thiab Ti-Ni-Nb kuj tau tshwm sim, thiab tau siv dav hauv engineering. Tam sim no, pua pua ntawm titanium alloys tau tsim nyob rau hauv lub ntiaj teb no, thiab muaj 20 ~ 30 nto moo alloys.
