ʻO Sillicon Carbide a me Silikia Nitride he palupalu maikaʻiʻole me ka metala molt. Ma waho aʻe o ka hoʻopiliʻana i ka teleiltrated e ka Magnesium, Nickel, Chromium a me nā mea kila maikaʻi loa, no laila uaʻoi aku ka maikaʻi o keʻano o kaʻoihana alumula.
Ma kēia pepa, ke kū'ēʻana o ka corrosior o ka silicon silicon silcide silicon silk
Wahi a kaʻikepili hoʻokolohua o 9 mau manawa o ka cycriling cycripling o 1080 i 4920 ° i nā hopena iʻole.
Ua hoʻonuiʻia nāʻano R-SIC a me SI3N4-SIC i hoʻonuiʻia me ka manawa corrosio a me ka nui o keʻano o ka corrosio. Ua hanaʻia ka helu o ka corrosio me ka pilina logririthmic o ka attenuation. (Kiʻi 1)
E ka loiloi o ka ikehu o ka ikehu, na R-SIC a me SI3N4-SIC i mau laulahipuhi ia lakou iho aole heimunimon Ma ka papa inoa XRD (Kiʻi 2 - Kiʻi 5)
Ma o ka loiloi sem, e like me ka manawa e hoʻonui ai ka manawa o ka corrosio,ʻo ka hana holoʻokoʻa o R-SIC a me SI3N4-DOUNTICIE. (Kiʻi 6 - Kiʻi 7)
ʻO ka maka o ka maka o ka maka σs / l> σs / g o ka interface ma waena o ka wai a me ka pākaukau ma waena o ka wai.
No laila,ʻo ka R-SIC a me SI3N4-SIC mau mea i nā mea eʻoi aku i ka corrosion e kū'ē i keʻano o keʻano a me keʻano liʻiliʻi. Eia nō naʻe, ua haʻahaʻa loa ke kumukūʻai o SI3N4-SIC i nā mea haʻahaʻa a ua hoʻohana ponoʻia i nā makahiki he nui.
