Phakathi kweenkqubo ezahlukileyo zokuphosa, intsimbi engenasici ikakhulu iphosa ngokulahla utyalo-mali okanye inkqubo yokulahla i-wax, kuba inokuchaneka okuphezulu kwaye yiyo loo nto ukuphoswa kotyalo-mali kukwabizwa ngokuba kukuphosa ngokuchanekileyo.
Isinyithi esingenasici sisishunqulelo sensimbi engenasici kunye neasidi enganyangekiyo. Ibizwa ngokuba yintsimbi engenasici enganyangekiyo kwimithombo yeendaba ebuthathaka njengomoya, umphunga kunye namanzi. Intsimbi ye-corrosion ibizwa ngokuba yintsimbi enganyangekiyo.
Ngenxa yomahluko ekwakhiweni kweekhemikhali phakathi kwentsimbi eqhelekileyo engenasici kunye nentsimbi enganyangekiyo ne-asidi, ukumelana kwabo nomhlwa kwahlukile. Isinyithi esiqhelekileyo esingenasici ngokuqhelekileyo asiyikuxhatshazwa kwimidiya ye-media corrosion, ngelixa i-asidi enganyangekiyo yensimbi ngokuqhelekileyo ayonakalisi. Igama elithi "intsimbi engenasici" alibhekiseli kuphela kuhlobo olunye lwentsimbi engenanto, kodwa likwabhekisa kwizinyithi ezingaphezulu kwekhulu zentsimbi. Insimbi nganye engenasici iphuhlisiwe inentsebenzo elungileyo kwicandelo layo lesicelo.
Insimbi engenasici ihlala yahlulwa yintsimbi ye-martensitic, i-ferritic insimbi engenasici, i-austenitic insimbi engenasici, i-austenitic-ferritic (i-duplex) intsimbi engenasici kunye nemvula eyenza lukhuni insimbi engatyiwa ngohlobo lwe-microstructure. Ukongeza, ngokuhambelana nokwenziwa kweekhemikhali, inokwahlulahlulwa ibe yintsimbi ye-chromium, intsimbi ye-chromium nickel kunye ne-chromium manganese nitrogen insimbi, njl.
Kwimveliso yokuphosa imveliso, uninzi lweesinyithi zokuphosa iintsimbi zigqityiwe ngotyalo-mali. Umphezulu castings steel stainless eziveliswa eyahlulayo utyalo agudileyo kunye nokuchaneka mbini kulula ukulawula. Kakade ke, iindleko zotyalo-mali ekubunjweni kweensimbi ezingenasici ziphakame ngokuthelekiswa nezinye iinkqubo kunye nezixhobo.
Eyahlulayo Investment, ekwabizwa ngokuba eyahlulayo ngqo okanye elahlekileyo wax eyahlulayo, isetyenziswa ngokubanzi njengoko inika eyahlulayo asymmetrical kunye neenkcukacha entle kakhulu ukuba yenziwe ngendlela engabizi. Inkqubo ibandakanya ukuveliswa kwesinyithi kusetyenziswa ukungunda okwenzileyo okwenziwe kwipatheni ye-wax replica. Amanyathelo abandakanyekayo kwinkqubo okanye ukulahlwa kwe-wax kulahlekile:
• Yenza iphatheni ye-wax okanye ikopi efanayo
• Khuphela ipateni ye-wax
• Tyala imali ngomzekelo we wax
• Susa ipatheni ye-wax ngokuyitshisa (ngaphakathi eziko okanye emanzini ashushu) ukwenza ukungunda.
• Nyanzela isinyithi esityhidiweyo sigalele ukungunda
• Ukupholisa kunye nokuQinisa
• Susa umjelo ophuma kubadlali
• Kugqitywe kupolishiwe ukugqitywa kotyalo-mali
