Isigaba esingenalutho sensimbi ye-SPA-H, ipuleti le-Corden Steel
1. Incazelo elula:
I-SPA-Hinsimbi yesimo sezulu, eyaziwa nangokuthi insimbi engagqwali emkhathini, ibhekisela ohlotsheni lwensimbi engenasici.ingxubevangeinsimbi enamandla kakhulu
equkethe inani elincane lezakhi ze-alloying, intengo ephansi, nokumelana nokugqwala okuhle emkhathini. I-alloying eyinhloko
izakhi yi-Cu, P, Cr, Ni, Si, Mn, V, RE, njll. Ngesikhathi kusetshenziswa insimbi yesimo sezulu, ifilimu yokuvikela eqinile futhi enamathiselwe ngokuqinile.
imikhiqizo yokugqwala izokwakheka kancane kancane ngaphezulu ukuze ivimbele umoya-mpilo, amanzi kanye nezinye izinto ezilimazayo ezisemkhathini
iqhubeka nokugqwala i-substrate, ukuze izinga lokugqwala linciphe kakhulu uma liqhathaniswa nensimbi ye-carbon. . Ngenxa yamandla ayo aphezulu futhi
intengo enengqondo, izindleko zokukhiqiza ziphansi kakhulu kunensimbi engagqwali. Izinga eliphezulu le-SPA-H lithi: JISG3125-2015.

4. Isicelo:
1) I-SPA-H iyinsimbi yesimo sezulu yokucubungula isitsha, ukusika nokushisela. I-SPA-H isetshenziselwa ikakhulukazi iziqukathi zomkhumbi,
amabhuloho ensimbi, imikhumbi namathangi ukuvimbela ukugqwala komkhathi.
2) Insimbi yesimo sezulu ye-SPA-H isetshenziswa kakhulu ukwenza iziqukathi. Imboni yezokuthutha zamakhonteyna inomlando wokudlula
Iminyaka engu-50 emhlabeni. Eminyakeni engu-30 edlule, izinto zokuhamba zezwe lami zazingenalutho. Kusukela izinguquko nokuvula, izwe lami
ukwakhiwa kwechweba kanye nokuthuthwa kwamabhokisi kuqhubekile nokuthuthuka. Ikakhulukazi eminyakeni yamuva, umphakathi wamazwe ngamazwe uye wabhekana
isimo “sesitsha esisodwa kunzima ukusithola.
5. Isimiso sokumelana nokugqwala:
Lapho insimbi ichayeka elangeni nasemoyeni, ukumelana nokugqwala kwayo kubaluleke kakhulu. Ngemuva kokungeza i-phosphorus, ithusi, i-chromium,
i-nickel nezinye izakhi zokulandelela ensimbi, kuzokwakhiwa ifilimu yokuzivikela eqinile futhi eqinile ebusweni bezinto zethusi, okuyinto
ingadlala indima ethile yokuvikela.
