Dab tsi yog hom hom corrosion cuam tshuam nrog 20g cov kav dej steel?
Thaum lub sijhawm pabcuam, 20g cov kav dej steel yuav raug teeb meem rau cov teeb meem corrosion xws li kev sib tsoo xeb, kev ntxhov siab corrosion, scc), thiab hydrogen clrittlement. Kev sib txawv ntawm corrosion feem ntau yog tshwm sim los ntawm kev sib tw noo lossis acidic ib puag ncig thiab ua kom pom tseeb raws li tag nrho cov phab ntsa tuab txo. Pitting corrosion yog tshwm sim los ntawm cov cheeb tsam electrochemical corrosion, uas ua rau me me pore-xws li tsis xws luag thiab muaj ntau hauv chloride-muaj xov xwm. Kev ntxhov siab corrosion cracking (SCC) los ntawm kev sib xyaw ua ke ntawm kev xeb thiab tensile muaj kev ntxhov siab thiab tuaj yeem ua rau pob txha tam sim ntawd. Hydrogen Clittlement tshwm sim thaum hydrogen atoms nkag rau cov hlau, txo nws txoj kev nruj.
Yuav ua li cas 20g steel steel yeeb nkab kho rau corrosion?
Cov Txheej Txheem Kev Tiv Thaiv muaj xws li txheej, plating, thiab kev tiv thaiv Cathodic. Cov txheej txheej tuaj yeem siv cov respoxy, polyurethane, lossis iav flake txheej los tsim lub cev lub cev ua kom muaj qhov nruab nrab corrosive. Cov kev kho ntawm plating xws li kub-dip galvanizing lossis electroplating chromium tuaj yeem txhim kho lub corrosion tsis kam ntawm cov kav hlau steel. Cathodic kev tiv thaiv yog siv rau faus lossis underwater dej thiab txwv tsis pub siv cov corrosies siv tau los yog ua kom zoo nkauj tam sim no. Tsis tas li ntawd, 20g steel kav tseem tuaj yeem kho nrog aluminizing lossis Chromizing txhawm rau txhim kho lawv cov oxidation kub tsis kam.
Dab tsi yog cov tiv thaiv corrosion rau 20g steel kav hauv qhov chaw kub kub?
Nyob rau hauv qhov kev kub-ib puag ncig muaj peev xwm kho tau nrog cov txheej txheem kub siab (xws li aluminium tiv thaiv txheej (xws li aluminium lossis chromizing) txhawm rau txhim kho oxidation tsis kam. Alizing cov ntaub ntawv ib co tuab eeside txheej ntawm cov yeeb nkab steel, tiv thaiv cov oxidation high-high-olidation corrosion. Tsis tas li ntawd, cov cua sov tiv thaiv alloy cladding lossis composite steel yeeb cov yeeb nkab sib xyaw, tuaj yeem siv los txhim kho corrosion tsis kam. Kev tswj hwm kev ua haujlwm kub thiab tsis txhob muaj kev kub siab kuj tseem muaj kev tiv thaiv kev tiv thaiv kev mob siab.
Dab tsi yog sab hauv phab ntsa tawm los tiv thaiv corrosion thev naus laus zis rau 20g steel kav?
Sab hauv phab ntsa los tiv thaiv corrosion thev naus laus zis suav nrog PT, PTFE), epoxy resin txheej, lossis xis cug kab tawm. Rau cov kav dej thauj cov xov xwm corrosive, xws li 20G + 316 l stainless hlau) tuaj yeem siv. Tsis tas li ntawd, electroless npib tsib xee plating lossis tshuaj tsuag-ntawm cov khaub noom txheej ceramic tuaj yeem siv tau rau cov pej xeem muaj zog. Polishing thiab passivation ntawm phab ntsa sab hauv tuaj yeem txo qis tshaj tawm cov adnhesion thiab txo qis kev pheej hmoo ntawm corrosion. Kev tu ib txwm thiab txhaj tshuaj ntawm tshuaj corrosion corrosion inhibitors tseem muaj kev ntsuas khoom txij nkawm.
Yuav ua li cas txhawm rau ntes corrosion hauv 20G steel yeeb nkab?
Corrosion kuaj pom muaj xws li ultrasonic thickness ntsuas (UT), ect), thiab infrared thermography. Ultrasonic thickness kuaj tuaj yeem saib cov yeeb nkab phab ntsa thinning thiab txiav txim siab qhov ntawm kev ua kom huv. Eddy kev sim tam sim no yog qhov haum rau ntes cov chaw sib tsoo thiab pitting. Thermared infrarraphy tuaj yeem ntes corrosion los ntawm cov thoob plaws hauv zos cov oxidation kub lossis rwb thaiv tsev rwb thaiv tsev. Tsis tas li ntawd, corrosion daim coupon los yog corrosion saib xyuas cov tshuab tuaj yeem siv los ntsuas cov qib corrosion hauv lub sijhawm. Rau cov raj xa hluav taws tseem ceeb, kev tshuaj xyuas ib txwm endoscopic lossis kuaj thiab tshuaj ntsuam kuj tseem.
