6, Titanium Bar Supply Status
Kub ua hauj lwm xeev, annealed xeev
7, Titanium pas nrig siv
Aerospace, aviation, navigation, nkoj, desalination, roj av, tshuaj lom neeg kev lag luam, machinery thiab khoom siv, nuclear fais fab khoom, fais fab khoom, tsheb thiab maus taus qhov chaw, kev ua si thiab leisure, kho mob qhov chaw, steel thiab metallurgy, high-tech teb.
8, Titanium Thiab Titanium Alloy Advantages
1, zoo corrosion kuj. Titanium alloy nyob rau hauv cov huab cua ntub thiab seawater media ua hauj lwm, nws cov corrosion kuj zoo dua li cov hlau tsis muaj steel; pitting, acid corrosion, kev nyuaj siab corrosion kuj muaj zog tshwj xeeb; alkali, chloride, chlorine, organic khoom, nitric acid, sulfuric acid, thiab lwm yam. Tab sis titanium muaj qhov txo qis oxygen thiab chromium ntsev media corrosion kuj tsis zoo.
2, kev ua haujlwm kub tsis zoo. Titanium alloy ntawm qhov kub thiab txias ultra-tsawg, tseem tuaj yeem tswj nws cov khoom siv kho tshuab. Kev ua tau zoo ntawm qhov kub thiab txias, qhov sib txawv tsis tshua muaj titanium alloy, xws li TA7, nyob rau hauv -253 degree kuj tseem tuaj yeem tswj tau qee qhov qib ntawm plasticity. Yog li ntawd, titanium alloy kuj yog ib qho tseem ceeb uas tsis muaj qhov kub thiab txias cov khoom siv.
3, tshuaj lom neeg kev ua si. Titanium cov tshuaj lom neeg yog loj, nrog atmospheric O, N, H, CO, CO2, dej vapor, ammonia thiab lwm yam tshuaj muaj zog. Thaum cov ntsiab lus carbon ntau dua 0.2%, TiC nyuaj yuav raug tsim nyob rau hauv titanium alloys; Thaum qhov kub thiab txias siab dua, lub luag haujlwm ntawm N tseem yuav tsim ib txheej txheej tawv tawv ntawm TiN;
Tshaj 600 degree, titanium absorbs oxygen los ua ib txheej tawv tawv nrog siab hardness; qhov nce ntawm hydrogen cov ntsiab lus tseem yuav tsim ib txheej embritled. Absorption ntawm cov pa roj thiab qhov tshwm sim nyuaj nkig txheej txheej qhov tob txog li 0.1 ~ 0.15 hli, qib hardening ntawm 20% mus rau 30%. Titanium cov tshuaj affinity kuj yog loj, yooj yim los tsim adhesion nrog kev sib txhuam nto.
4, thermal conductivity thiab elasticity yog me me. Titanium's thermal conductivity λ=15.24W / (mK) yog li 1/4 ntawm npib tsib xee, 1/5 ntawm hlau, 1/14 ntawm txhuas, thiab ntau yam titanium alloys muaj thermal conductivity ntawm li 50% qis dua qhov ntawd. ntawm titanium. Lub modulus ntawm elasticity ntawm titanium alloy yog hais txog 1/2 ntawm cov hlau, yog li nws rigidity tsis zoo, yooj yim rau deform, tsis haum rau ua slender rods thiab nyias-walled qhov chaw, thiab lub rebound ntawm machined nto thaum txiav yog loj heev, li 2 mus rau 3 npaug ntau npaum li cov hlau tsis muaj steel, uas ua rau muaj kev sib txhuam hnyav, adhesion thiab kev sib txuas ntawm lub cuab yeej lub ntsej muag lub ntsej muag.
