CERAMIC/METAL COMPOSITE MATERIAL |
摘要 |
A CERAMIC/METAL COMPOSITE MATERIAL A ceramic/metal composite material comprises a surface ceramic coating comprising an oxidised alloy of copper stabilized by being in solid solution with nickel oxide or manganese oxide on a substrate which is an oxidation resistant alloy essentially devoid of copper or any metal which oxidises more readity than copper. The composite is made by oxidising a copper-based alloy on a substrate and simultaneously oxidising the substrate surface to form an oxygen-barrier interface, for example a chromium oxide layer formed on an alloy of chromium with nickel, iron and/or cobalt. The composite may be used as anode substrate for a cerium oxyfluoride coating used in aluminum electrowinning. |
