Abstract
Provided are methods related to preventing hydrocarbon residue buildup in engine, exhaust-gas-system or powertrain components. Prevention is achieved by applying coating of a mixed metal oxide via a suspension plasma spray.
Claims17
A method of applying a coating to an engine, exhaust-gas-system or powertrain component, the method comprising suspension plasma spraying a coating a mixed metal oxide onto an engine, exhaust-gas-system or powertrain component, wherein the coating contains a component that oxidizes hydrocarbons.
A method of applying a coating to an engine, exhaust-gas-system or powertrain component, the method comprising suspension plasma spraying a coating onto an engine, exhaust-gas-system or powertrain component, wherein the coating comprises a mixed metal oxide comprising at least two metals selected from the group consisting of Al, Ti, Ce, Pr, La, Y, Nd, Mn, Zr and combinations thereof.
A method of applying a coating to an engine, exhaust-gas-system or powertrain component, the method comprising:
- forming a suspension by dispersing mixed metal oxide particles in a liquid;
- feeding and injecting the suspension into a plasma torch or plume;
- and
- plasma spraying of the suspension towards the surface of an engine, exhaust-gas-system or powertrain component.
