Maemong a ts'ebeletso ea cyclic, Inconel 625 e boloka matla a mokhathala le botsitso bo boholo ka tahlehelo e ke keng ea lekanngoa taolong ea oxidation.
Mokhoa oa Tlhahiso le Phekolo ea Mocheso
Liphaephe le li-tubes li etsoa ka mokhoa o chesang oa extrusion kapa setšoantšo se batang 'me ka mor'a moo tharollo e kenngoa ka 1090-1150℃(1995-2100℃F) e lateloa ke ho tima ka potlako ho tsosolosa khanyetso ea kutu. Mefuta e cheselitsoeng e hlahisoa ke ts'ebetso ea TIG kapa plasma tlas'a tšireletso ea khase e inert.
Ho etsa ka nepo le boholo bo batang bo boloka ho tšoana ha lebota, ha ho kha le ho khantša ho khanyang ho tsosolosa filimi e sireletsang ea Cr₂O₃. Ho etsa tlhahiso le ho hlahloba ho tsamaellana leASTM B444, B705, le B704litekanyetso.
Corrosion Resistance ho pholletsa le Media
The alloy's dual action-nickel-filimi ya chromium oxide bakeng sa maemo a oxidizing le molybdenum-niobium reinforcement bakeng sa ho fokotsa dibaka{3}}e etsa hore ho be le botsitso bo pharalletseng ba dikhemikhale:
- Metsi a leoatle le chloride:E hanana le likoti, maphao, le khatello ea maikutlo-ho phatloha ho hoholo.
- Li-acid tse oxidizing (nitric, chromic):Chromium e boloka ho khomarela ha oxide ho mocheso.
- Ho fokotsa acid (hydrochloric, phosphoric):Molybdenum e thibela tlhaselo ea lehae.
- Khase e bolila (H₂S):E tsitsitse khahlano le khatello ea maikutlo ea sulfide bakeng sa ts'ebeletso ea oli le khase.
