A metal alloy in particulate form is plasma flame sprayed into an appropriately shaped depression 12 in a mould 10, so as to produce a coating test piece in a desired shape. The walls of the mould serve to constrain the affects of residual stresses generated by the combining of molten and semi molten particles, and so as a test piece results which is a more integral, self supporting structure than those produced hitherto. |
