Titanium thiab titanium alloys muaj qhov zoo xws li lub zog tshwj xeeb, kev tiv thaiv corrosion, siab -kub tsis kam, thiab biocompatibility zoo, thiab tau dav siv hauv cov haujlwm tseem ceeb xws li aerospace, kev tiv thaiv hauv tebchaws, marine nkoj, thiab biomedical applications. Nyob rau tib lub sijhawm, titanium thiab nws cov alloys yog qhov ua rau oxidation thiab muaj qhov tsis zoo xws li tsis tshua muaj zog, tsis zoo thermal conductivity, thiab muaj peev xwm zoo electrode, uas txo lawv cov kev siv. Kev kho deg tuaj yeem hloov kho lub xeev ntawm lub substrate, txhim kho qhov pom kev pom thiab kev ua tau zoo, thiab txawm tias muab qee yam haujlwm tshiab uas tsis muaj nyob rau hauv substrate. Nws yog ib qho tseem ceeb heev rau kev txhim kho lub neej ntev, kev cia siab, thiab nthuav dav daim ntawv thov ntawm titanium thiab titanium alloy khoom.
Kev kho qhov chaw tsim nyog tuaj yeem hloov kho qhov chaw ntawm titanium thiab titanium alloy cov khoom, yog li muab lawv cov tsos zoo, txhim kho cov khoom ntawm lub substrate, thiab txawm muab qee yam khoom tshiab uas lub substrate nws tus kheej tsis muaj. Qhov no yog qhov tseem ceeb heev rau kev txhim kho lub neej ntev thiab kev ntseeg siab ntawm titanium thiab titanium alloy cov khoom, nrog rau kev nthuav dav lawv daim ntawv thov. Cov kws tshawb fawb hauv tebchaws thiab thoob ntiaj teb tau ua cov kev tshawb fawb dav dav txog qhov no, uas tuaj yeem muab faib ua plaub yam hauv qab no: ① Kev hloov kho deg: kho qhov chaw ntawm lub substrate kom ua tau raws li qhov yuav tsum tau ua ntawm cov khoom, xws li nto roughness, uas ua haujlwm raws li cov txheej txheem ua ntej thiab kev ua haujlwm yooj yim rau lwm yam kev kho deg technologies. Raws li pom hauv daim duab 1; ② Nto hnav thiab corrosion kuj: txhim kho qhov hnav thiab corrosion kuj ntawm titanium thiab titanium alloys, uas yog tam sim no cov kev tshawb fawb tshaj plaws thiab cov neeg laus tshaj plaws ntawm cov txheej txheem kho deg rau titanium thiab titanium alloys; ③ Cov xim pleev xim rau saum npoo: muab cov titanium thiab titanium alloys tshwj xeeb nrog cov xim tshwj xeeb thiab textures nto los ntawm kev hloov kho saum npoo thiab txheej thev naus laus zis, uas muaj txiaj ntsig zoo engineering. Raws li pom hauv daim duab 2; ④ Kev sib cais ntawm qhov saum npoo: ua tiav kev sib cais ntawm titanium thiab titanium alloys los ntawm ib puag ncig ib puag ncig los ntawm cov txheej txheej txheej txheej los tiv thaiv kev sib cuag corrosion, thaiv cov ingress ntawm corrosive media, los yog kev tsiv teb tsaws ntawm cov teeb meem ions. Qhov no muaj kev cia siab rau daim ntawv thov dav hauv marine engineering, biomedical fields, thiab lwm qhov chaw.
