    Abstract: A movable wall member in the form of an exhaust valve spindle (1) or a piston (7) in an internal combustion engine is on the side of the wall member facing a combustion chamber provided with a hot-corrosion-resistant material (5, 14) made from a particulate starting material of an alloy containing nickel and chromium which by a HIP process has been unified to a coherent material substantially without melting the starting material. The corrosion-resistant material has a hardness of less than 310 HV measured at approximately 20 DEG C after the material has been heated to a temperature within the range of 550-850 DEG C for more than 400 hours.

    Abstract: Method of operating a catalytic ignition internal combustion engine wherein the fuel is injected into a combustion chamber (24) at a time near maximum compression such that at least part of the fuel impinges upon an oxidation catalyst surface (14) comprising a portion of the wall (11) of said combustion chamber, said catalytic surface (14) being insulated from the surroundings external to the combustion chamber by a low thermal conductivity material (13), said catalytic surface (14) preferably comprising platinum. Also disclosed are combustion chambers constructed specially for the use of this method and the methods of constructing them.

    Abstract: A method for preventing the deposit on a metal surface of thermal degradation products selected from metal sulfides, metal oxides or mixtures thereof derived from the reaction of sulfur, oxygen or mixtures thereof in hydrocarbon fluid with metal atoms which diffuse to the surface, comprises applying to the metal surface a diffusion barrier coating comprising a thermally stable metal oxide, amorphous glass, metal fluoride or mixtures thereof, the metal oxide, amorphous glass, metal fluoride or mixtures thereof being applied by chemical vapor deposition (CVD), e.g. by effusive CVD of an organometallic compound on the surface without the use of carrier gas, without pre-oxidation of the surface and without thermal decomposition of the diffusion barrier coating material. Examples of coating materials deposited by effusive CVD are Ta₂0₅, Si0₂, Ti0₂, spinel and Al₂0₃. Articles having the coated surfaces find utility in components subjected to high temperatures wherein the components are in contact with hydrocarbon fluids without additives, without special attention to quality control and without the need for special processing.
