Classification ntawm corrosion qauv ntawm titanium

Titanium corrosion qauv suav nrog kev txhim kho corrosion thiab hauv zos corrosion ob pawg: kev txhim kho corrosion yog ib qho kev nthuav dav thiab cov qauv corrosion; Hauv zos corrosion yog txheeb ze rau kev txhim kho corrosion, hauv zos corrosion qauv tuaj yeem muab faib ua: crevice corrosion, pitting corrosion, kev nyuaj siab corrosion cracking, hluav taws xob coupling corrosion, abrasion, hydrogen absorption thiab hydrogen embrittlement.

(1) crevice corrosion: nyob rau hauv ntug los yog folded ntug thiab tsub zuj zuj ntawm nyob ze crevices ntawm lub corrosion tshwm sim, feem ntau tshwm sim nyob rau hauv lub nqaim crevices.

(2) pitting corrosion: corrosion tshwm sim nyob rau hauv lub qhov qhib, xws li CI =, Br, I thiab lwm yam halogen ions nyob rau hauv lub xub ntiag ntawm corrosion tshwm sim los ntawm qhov teeb meem.

(3) kev nyuaj siab corrosion cracking: nyob rau hauv ib qho chaw, vim lub luag hauj lwm ntawm tensile kev nyuaj siab, ib tug nkig puas.

(4) Abrasion: cov kua yog raug rau txhua yam kev txiav txim los txhawb qhov tshwm sim ntawm electrochemical corrosion. (5) galvanic coupling corrosion: tseem hu ua dissimilar hlau tiv thaiv corrosion, yog ib qho hluav taws xob luv luv-circuit xeev, txhawb lub peev xwm tsawg ntawm cov hlau corrosion tshwm sim.

(6) hydrogen absorption thiab hydrogen embrittlement: hydrogen yuav raug tshem tawm ntawm cov khoom, thaum tus nqi coj tawm ntau tshaj qhov kev daws teeb meem ntawm cov khoom, tsim cov nkig hydride, hydrogen embrittlement phenomenon.
