Definitions

  • references following to a metal or metals include an alloy or alloys of the metal or metals, unless otherwise indicated.
  • the second coating may be formed by thermal spraying, for example by vacuum- or air-plasma spraying and in particular the coating may be formed by the deposition of one or more layers.
  • a plurality of layers can be employed to form a step-wise gradation of the metal to ceramic ratio as mentioned above.
  • a metallic substrate 10 has a first coating 11 of a metal or alloy, a second coating 12 of a mixture of one or more metals and alloys at least one ceramic, a third coating 13 of at least one ceramic and a fourth non-porous coating 14 of precious metal or alloy.
  • the proportion of metal or alloy to ceramic decreases from this interface with the first coating 11 to the interface with the third coating 13 as schematically depicted with '-' for metal or alloy of the first and second coatings and '+' for the ceramic of the second and third coatings.
  • Example 16 was not tested as cracks appeared prior to platinum coating. This was probably due to the thickness of the third coating which was formed from thirty layers of alumina. The results obtained for Examples 14, 15 and 20 with a second coating having the amount of metal decreasing from the interface with the first coating to the interface with the third coating are better than for Examples 17, 18, 19 and 21 where the proportion of metal to ceramic was the same through the thickness of the second coating.
