1. Kev kho cua sov rau saum npoo thiab microstructure
Cov no tsis yog "coatings", tab sis yog qhov tseem ceeb ntawm qhov chaw thiab kev kho mob microstructural:
Kev daws Annealing
Qhov kub thiab txias: 1100-1200 degree, ua raws li cua txias.
Lub hom phiaj:
Homogenize lub microstructure
Dissolve precipitates
Txhim kho ductility thiab corrosion kuj
Teem lub grain loj kawg
Kev Nyuaj Siab Kev Nyuaj Siab
Ua tom qab vuam los yog hnyav sib sau.
Qhov kub thiab txias: 850-950 degree, ua raws li cua txias.
Lub hom phiaj:
Txo cov kev ntxhov siab seem
Txo qhov kev pheej hmoo ntawm kev ntxhov siab corrosion tawg (SCC)
Oxidation Resistance Treatment (Pre{0}}oxidation)
Cua sov nyob rau hauv cov huab cua ntawm qhov kub thiab txias los ua ib tug ntom, adherent Cr₂O₃- nplua nuj oxide txheej.
Lub hom phiaj:
Txhim kho kev tiv thaiv ntxiv rau oxidation thiab scaling nyob rau hauv siab -kev pab kub
Feem ntau ua raws li ib feem ntawm cov txheej txheem tsim khoom rau qhov cub
2. Mechanical Surface Treatments
Grit Blasting / Txhaj Blasting
Media: alumina, silica, lossis stainless hlau txhaj tshuaj.
Lub hom phiaj:
Tshem tawm cov nplai, oxide txheej, thiab cov kab mob ntawm qhov chaw
Txhim kho qhov chaw tiav thiab qhov tsos
Muab qhov sib xws, me ntsis ntxhib saum npoo rau txheej tom ntej lossis pleev xim
Pickling
Siv cov kua qaub (xws li HF/HNO₃ sib tov) kom tshem tawm cov nplai thiab cov cua sov- cuam tshuam cov txheej.
Lub hom phiaj:
Ntxuav qhov chaw ua ntej vuam, txheej, lossis sib dhos
Txhim kho corrosion kuj los ntawm kev tshem tawm cov khaubncaws sab nraud povtseg
Mechanical Polishing / Sib Tsoo
Lub hom phiaj:
Ua tiav ib daim iav du lossis daim iav{{0} zoo li qhov chaw tiav
Tshem tawm qhov tsis xws luag ntawm qhov chaw (scratches, pits)
Txhim kho qaug zog tiv thaiv hauv qee kis
Txhuam / Siv Sib Tsoo
Lub hom phiaj:
Tau ib tug uniform matte los yog directional tiav
Tshem cov weld spatter thiab kub tint tom qab vuam
3. Cov txheej txheem tiv thaiv thiab kev hloov kho deg
Inconel 601 twb tau zoo heev -kub oxidation thiab corrosion kuj, yog li txheej txheej feem ntau xaiv tau thiab daim ntawv thov- tshwj xeeb:
Anti-Carburization Txheej
Rau kev pabcuam hauv carburizing atmospheres (piv txwv li qee qhov chaw ua cua sov).
Hom hom: aluminide coatings, chromide coatings, los yog overlay coatings.
Lub hom phiaj:
Tiv thaiv carbon ingress thiab tom qab embrittlement
Thermal Barrier Coatings (TBCs)
Hauv qee qhov kub siab heev - daim ntawv thov kub, lub tsho tiv no ceramic (xws li YSZ) nrog lub tsho tiv no tuaj yeem siv.
Lub hom phiaj:
Txo cov cua sov tso rau hauv lub substrate
Txhim kho cov khoom siv lub neej ntawm qhov kub thiab txias heev
Xim / Organic Txheej
Siv feem ntau rau kev txheeb xyuas, kev zoo nkauj, lossis kev tiv thaiv atmospheric corrosion ntawm qhov kub qis.
Nto yog feem ntau blasted thiab primed ua ntej kom ntseeg tau adhesion.
Electroplating
Tsis tshua muaj rau Inconel 601, tab sis npib tsib xee lossis chromium plating yuav siv tau tshwj xeeb rau kev hnav lossis kho kom zoo nkauj.
Kev saib xyuas yuav tsum tau ua kom tsis txhob muaj hydrogen embrittlement thiab xyuas kom muaj kev sib raug zoo nrog cov khoom siv hauv paus.
4. Weld-Txoj kev kho qhov chaw
Ncej -Wel Cleaning
Tshem tawm ntawm qhov sib tsoo, slag, thiab tshav kub tint (discoloration) los ntawm:
Sib tsoo / txhuam
Pickling lossis electrochemical tu
Lub hom phiaj:
Restore corrosion kuj
Tiv thaiv crevice corrosion ntawm welds
Passivation
Txawm hais tias muaj ntau dua rau cov hlau tsis muaj steel, passivation -zoo li kev kho mob (acid tu) tuaj yeem siv rau ntawm Inconel 601 rau:
Tshem tawm cov hlau dawb thiab lwm yam kab mob
Txhawb kev tsim kom huv si, tiv thaiv oxide txheej
