Sim zam kom tsis txhob muaj kev ntxhov siab loj hauv kev ua thiab kev tsim khoom sib dhos, lossis siv cov annealing thiab lwm txoj hauv kev ntawm kev ntxhov siab seem. Seamless luj tshib manufacturers qhia lub ntsiab lus ntawm corrosion qaug zog thiab corrosion qaug zog yog hais txog lub crispy so los ntawm kev sib xyaw ntawm cov khoom nyob rau hauv qhov kev txiav txim ntawm cross-transformation kev nyuaj siab thiab corrosive nruab nrab. Muaj ntau hom kev ntxhov siab hauv kev sib deev, thiab lub voj voog kev ntxhov siab ntawm kev sib hloov kev ntxhov siab thiab kev nyuaj siab ntxhov siab rau kev hloov pauv yog qhov tshwm sim. Kev qaug zog yog ib qho teeb meem uas txhua yam khoom siv yuav raug ntsib. Feem ntau cov ntaub ntawv qaug zog uas tuaj yeem pom hauv phau ntawv qhia tuaj yeem kuaj tau hauv huab cua. Corrosion qaug zog feem ntau yog hais txog kev qaug zog hauv qhov nruab nrab corrosive tsuas yog huab cua. Corrosion qaug zog yog ib qho teeb meem loj uas tau ntsib los ntawm ntau yam khoom uas cuam tshuam los ntawm circulating loads hauv qhov tseeb ntawm qhov project. Piv txwv li, lub pusher turbine thiab turbine blades ntawm marine platform tsim petrochemical khoom feem ntau tshwm sim, ua rau muaj kev puas tsuaj loj. Nyob rau tib lub sijhawm, kev poob nyiaj txiag los ntawm qhov kev puas tsuaj no kuj tseem ceeb heev. Raws li kev txheeb cais, qhov teeb meem tshwm sim los ntawm corrosion qaug zog yog thib ob nkaus xwb. Cov yam ntxwv ntawm corrosion qaug zog yog cov yam ntxwv hauv qab no.
Daim duab nkhaus ntawm corrosive qaug zog yog txawv los ntawm cov duab nkhaus ntawm lub zog ntshiab zog. Tsis muaj kev txwv tuag rau corrosive qaug zog. Seamless luj tshib manufacturers qhia qhov qaug zog kev ua tau zoo ntawm cov khoom siv engineering yog txiav txim siab los ntawm kev qaug zog nkhaus tau los ntawm kev sim qaug zog. Thaum cov hlau tsis raug kev txom nyem los ntawm corrosion tej yam kev mob, tsuas yog thaum lub cyclic kev nyuaj siab tshwm sim, tus nqi kev nyuaj siab yuav raug puas tsuaj rau ib tug tej yam kev txwv. Tus nqi hu ua fatigue limit lossis qaug zog. Vim tias tsis muaj kev txwv qaug zog rau corrosion qaug zog, cov khoom siv tuaj yeem tawg nyob rau hauv cov xwm txheej tsis tshua muaj kev ntxhov siab. Feem ntau, qhov kev ntxhov siab ntawm lub voj voog ntawm lub voj voog yog siv los ua qhov corrosive qaug zog, thiab nws yog siv los ntsuas qhov kev ua haujlwm ntawm kev qaug zog ntawm cov khoom siv. Corrosion qaug zog txawv, thiab feem ntau tshwm sim nyob rau hauv cov khoom thiab tej yam kev mob, thaum corrosive qaug zog tsis xaiv. Tsuav yog muaj qhov nruab nrab corrosive, cov hlau ntshiab kuj tuaj yeem ua rau qaug zog corrosion. Tsis muaj ib qho kev sib txuas ntawm corrosive fatigue siv thiab tensile zog.
Cov kev sib raug zoo ntawm corrosion qaug zog lub zog ntawm cov hlau nyob rau hauv seawater yog tsis pom tseeb. Seamless luj tshib chaw tsim tshuaj paus qhia tau hais tias lub corrosive qaug zog siv nyob rau hauv cov huab cua tsub kom nrog nce tensile zog, thiab muaj ib tug tej yam kev sib raug zoo. Corrosion qaug zog tawg feem ntau yog los ntawm qhov tsis zoo ntawm qhov chaw corrosion los yog daim duab saum npoo nruab nrab rau steel corrosion qaug zog. Lawv feem ntau muaj ntau qhov sib tsoo hauv cov pab pawg, thiab nthuav dav raws cov kev taw qhia ntawm kev ntxhov siab vertically. Cov kab nrib pleb feem ntau yog hnav cov siv lead ua, nrog rau cov siv lead ua thiab cov sib xyaw ua ke, thiab cov kab nrib pleb ua dav dua nrog corrosion. Lub corrosion qaug zog tawg muaj cov yam ntxwv ntawm corrosion thiab corrosion corrosion thiab qaug zog thiab qaug zog. Cov txheej txheem ntawm corrosion qaug zog thiab qaug zog qaug zog muaj xws li cyclic yas deformation, micro-crack nucleus, cov kab nrib pleb me me, thiab cov kab nrib pleb me me los txuas thiab sib sau ua ke los ua ib lub sijhawm luv luv, thiab macro crack expansion txuas ntxiv mus. Vim tias corrosive qaug zog yog qhov tshwm sim los ntawm kev cuam tshuam ntawm kev sib hloov ntawm kev ntxhov siab thiab corrosive nruab nrab, hauv kev tshawb fawb txog kev ua haujlwm, kev qaug zog ntshiab yog feem ntau qiv nrog cov nyhuv electrochemical corrosion thiab hydrogen brittle mechanism. Lub mechanism ntawm corrosive qaug zog tau tsim. Ntawm no yog ib qho kev qhia luv luv rau cov txheej txheem ntawm pore dab noj hnub kev nyuaj siab concentration qauv thiab qhov tseem ceeb dissolving qauv mechanism.
