Lug txhim khu kev tsheb ncua kev kawm ntawv lub caij nplooj hlav hlau rau cov ua tau thiab yuav tsum raug luv vim hydrogen hauv ib cheeb tsam corrosive uas ua rau ntawd, puas nyhav. Nyiajpoom teb rau alloy nws hais txog kuj ntxiv zoo li corrosion deev ntau txog lub caij nplooj ntoos hlav hlau uas hlav dav hlau JISSUP12 thiab lub caij nplooj ntoos hlav siab zog hlau HDS13, thiab kuj ntxiv zoo li corrosion deev siab loj zog lub caij nplooj hlav steel series HDS13M mus lawm 5mass % NaCl dej kua hauv lub pheej ntub thiab qhuav corrosion Hou ntawm SSRT mus kuaj, raws li cov tshuaj tiv thaiv corrosion Hou ua hydrogen hauv hlau nyob hauv cov kev coj cwj pwm thiab SSRT kuaj cov yam ntxwv , kev tshawb fawb tau ua hauj corrosion ntsiab lus zoo li txiv neej thiab qeeb puas rhiab heev ntawm kev sib raug zoo, proceeds tau tom qab.
Ntxiv ib qho ntxiv caij cov pitting ua hauj corrosion Ni, thiab Cr, Cu, Mo thiab b thiab alloy tshiab uas muaj zog npaum cas caij nplooj ntoos hlav steel HDS13M series pitting kuj ua ntau tshaj li Ni thiab yooj yim dua Mo ntawv ntawm lub HDS13 caij nplooj ntoos hlav hlau.
Uas muaj tuaj raws Vand #39; cq100 pitting corrosion kuj txog lub caij nplooj ntoos hlav steels, ua kom muaj qhov voos kheej-KHEEJ thiab yog qhov tob ntawm pitting corrosion me me, nws txoj kev tsis ncaj ncees los kuj me me.
Raws li SSRT ntub thiab qhuav ua ntej thiab tom qab cov cyclic corrosion sim tau, yog Vand #39; cq100 yog kub, caag thiab tu lub sij hawm, qhov lower tus siab kawg thauj khoom.
Tsis ntub dej qhuav cyclic corrosion kuaj txog hydrogen thermal soj ntsuam, yuav saib lub kos rau hauv cov 673 ~ 773K tsam ntawm lub hydrogen ncov. Siv cov nyiaj uas tseg tau txoj kev mus saib cov hydrogen, lub ncov thiab tom qab corrosion interface xeb thiab steel hnov kom tus concentration hydrogen xub.
Ntawm hydrogen uas Day ntau zog rau lawv xwb, rhuav lub sij hawm uas standardization shortens, nyhav ntawd, puas yuav muaj feem cawm.
Los ntawm cov concentration of hydrogen hauv lub interface thiab ces ncu rhaub kom ntau tshaj 673K, ces nws tso tawm, yuav muaj feem cawm vim ntub dej qhuav cyclic corrosion neeg mob ntawd, puas ntawm restores.
Ntxiv pab txhim kho pitting corrosion kuj uas hais tau raug generated them mus dua corrosion ntub dej ntawm hydrogen txo, khees me ntsis lawm ncua puas kuj zog rau lub caij nplooj ntoos hlav hlau alloy.
