Title: A metal article with thermal barrier coat and a method for use thereof
Inventor: RIKERBY DAVID STEFFORD
IPC: C23C28/00
Filed: 1999-01-11
Abstract: A metal article (30) contains connective coat (34) on the metal article 30) and ceramic coat (38), forming a thermal barrier on the connective coat (34). The ceramic coat (38) forming the thermal barrier contains numerous column-like granules (40), disposed perpendicularly to the surface of the metal article (30). Each column-like granule (40) has many layers (42, 44). Some layers (44) have sub-granules (48), disposed at a sharp angle to the surface of the metal article (30) to form voids (50) between nearby sub-granules (48). The voids (50) are disposed at a sharp angle to the surface of the metal article (30) and, thus, reduce specific conductivity of the ceramic coat (38), forming the thermal barrier. Some layers (42) have sub-granules (46), disposed perpendicularly to the surface of the metal article (30) to provide an erosion resistance.

Proposed method is implemented in internal combustion engine provided with compression chamber, combustion chamber and working chamber. In compression chamber, charge of compressed air or fuel mixture is taken in, compressed and delivered through open intake valve into combustion chamber. In combustion chamber fuel mixture in taken in or formed, is ignited and burning gases are discharged into working chamber through open outlet valve of combustion chamber. In process of burning, gases set into rotation engine shaft mechanism. Then exhaust gases from working chamber are discharged into atmosphere. Engine can be provided with one or several combustion chambers. If engine is provided with several combustion chambers, charge of compressed air fuel mixture from compression chamber is delivered in turn into several combustion chambers fuel mixture taken in combustion chamber or formed in combustion is ignited at closed intake and outlet valves and phase of burning takes place in constant volume. Then burning gases are discharged in turn from each combustion chamber into working chamber. In process of working stroke in working chamber, burning of fuel mixture takes place at increasing of aggregate volume of combustion chamber and working chamber at reduction of pressure and temperature of burning gases. If engine is furnished with only one combustion chamber, it is scavenged and charged with compressed charge. Working fuel mixture taken in or formed in combustion chamber is ignited at intake and outlet valves closed, and burning phase takes place in constant volume. Then gases form combustion chamber are discharged into working chamber in which burning of mixture takes place at increase of aggregate volume of combustion chamber and working chamber at reduction of pressure and temperature of burning gases.
