Abstract

A protective ceramic coating for a component of a weapon subject to high thermal stress is formed on a chemically decomposable core (3), for example of aluminium, and has a ceramic layer (4) applied by flame spraying. Cermet layers (5 and 6) in which the ceramic content of the layer (5) is less than that of the layer (6) and a metal layer (7) which connects with the surface of the component (not shown). The connection with the component is made by a shrinkage process preferably whilst the core (3) is still present. <IMAGE>
