Lub electrochemical corrosion kuj ntawm TB5 titanium alloy rau offshore roj drilling thiab cov kav dej yog optimized, Cov teebmeem ntawm cov pa tshuaj thiab kev laus thaum tshav kub kub kev kho mob ntawm nws electrochemical corrosion tus cwj pwm tau kawm. Cov txiaj ntsig kev sim qhia tau hais tias cov nplej loj ntawm TB5 titanium alloy nce maj mam nrog qhov nce ntawm cov tshuaj kub. Cov qoob loo loj tom qab kev daws teeb meem ntawm 950 degree yog 125 loj dua li tom qab kev daws teeb meem ntawm 800 degree μ m. Qhov kev daws teeb meem qis dua, qhov me me ntawm cov nplej loj, thiab qhov zoo dua qhov kev tiv thaiv corrosion;

Qhov kev tiv thaiv corrosion ntawm cov hlau yog qhov zoo dua tom qab kev laus, thiab qhov kev txhim kho corrosion thib ob nce nrog qhov nce ntawm kev laus kub Cov ntsiab lus ntawm cov theem tau nce ua ntej thiab tom qab ntawd txo qis, thiab corrosion kuj ntawm cov alloy yog zoo ib yam li cov theem nrab. Nws yog ncaj qha proportional rau theem cov ntsiab lus.

Cov txiaj ntsig tau pom tias cov txheej txheem kho cua sov zoo tshaj plaws nrog electrochemical corrosion kuj yog 800 degree cov tshuaj tov ntxiv rau 500 degree kev laus, thiab tus nqi corrosion yog 1.44 × 10-3 mm / a.
