Hydrogen Corrosion inogona kuitika muAmmonia synthesis, hydrogen desuguzation hydrogenation maitiro uye peturu inomenesa zvikamu. Carbon simbi haina kukodzera kushandiswa mukudzvinyirira yakakwira hydrogen kuisirwa kumusoro 232 ° C. Hydrogen inogona kushandiswa musimboti uye ita nedare rembiru pamiganhu yezviyo kana munzvimbo dzeparamende kuti dzigamuchire methane. Methane (gasi) haigone kusarudzika kunze kwesimbi uye inounganidza, kugadzira mavara machena uye marara kana chero cheizvi simbi.
Kuti udzivise kugadzirwa kweMethane, Carburization inofanirwa kutsiviwa neyekugadziriswa materu, simbi inofanira kuwedzerwa ku chromium, vanadium, titanium kana kudhiraivha. Yakanyorwa kuti yakawedzera chrromium yezvinyorwa zvinotumira tembiricha yepamusoro uye hydrogen zvimanikidzwa kuti aumbe chromium baroti mumarara aya, uye kuti yakagadzikana kurwisa hydrogen. Chromium Stelels uye Austenitic Stainless STELS ine zvinopfuura gumi nemaviri Chrombium ndeyekushora zvinokonzeresa mashandisirwo ezvemamiriro ezvinhu epamusoro (kupisa pamusoro pe593 ° C).
Mitezo yakawandauye madhiri haaite ne molecular nitrogen panzvimbo yakakwira tembiricha, asi atomic nitrogen inogona kuita nemakumbo mazhinji. uye inopinda mune simbi kuti iite brittle nitride sosi yepasi. Iron, Aluminium, Titanium, Chromium uye zvimwe zvinhu zvekunyepedzera zvinogona kuita izvi maitiro. Iko kukwira kwakanyanya kweatomiki nitrogen ndiko kuora kweAmoni. Amonia Decompures muAmmonia Converters, Ammonia kugadzirwa kweIters uye nitriding magetsi anoshanda pa371 ° C ~ 593 ° C, imwe mamiriro ~ 10.5kg / mm².
Mune aya matenga, chromium carbide inoonekwa mune yakadzika chromium simbi. Inogona kunge yakagadziriswa neatomu nitrogen nitromijit nitride, uye kusunungurwa kwekabhoni uye hydrogen yekugadzira methane, sezvataurwa pamusoro apa, izvo zvingabva zvaburitsa mavara machena nemarara, kana mumwe wavo. Nekudaro, ne chromium zvirimo pamusoro pa12%, iyo carbides mune idzi nzizi dzakasimba pane chromium nitride, saka maitiro epamberi haaiti, saka stainless manje anoshandiswa munzvimbo dzakasimba dzevaridzi neanopisa.
Iyo mamiriro esimbi isina tsvina muAmoni inotarisirwa nekudziya, kumanikidzwa, gasi kusimbisa uye chromium-nickel zvemukati. Kuedza kwemunda kunoratidza kuti huwandu hwekushora (kudzika kwesimbi yakashandurwa kana kudzika kwesimbi kana martensitic kana martensitiki simbi yakakwirira kupfuura iyo yeAustenitic svutugadzike, iyo inodzivirira kuora neakakwirira yezvinyorwa. Sezvo zvirimo zvinowedzera huwandu hwekuwedzera hunowedzera.
Austenitic Stainless Simbi muSky Tembiricha Hargen Mapor, Corrosion yakakomba, Fluorine iri kuwedzera kupora kupfuura chlorine. Kune yakakwira ni-c r stainless simbi, iyo yekumusoro muganho weiyo tembiricha mune yakaoma gasi fluorine ye 249 ℃, chlorine ye 316 ℃.
