Application of Alumina Ceramic Powder in Combustion Engine Components to Thermal Insulation 2004-01-3239

In a wide variety of applications, mechanical components have to operate under severe conditions, such as high load, speed or temperature and hostile chemical environment. Thus, ceramic coatings produced by thermal etching techniques are widely used for a range of industrial applications, to confer wear and erosion resistance, corrosion protection and thermal insulation. Thus, this work has as objective to deposition of the alumina ceramic powder by plasma etching in the combustion engine components (piston, valves, combustion camera), actuating such as thermal insulation to increase temperature in the combustion camera and consequently improvement of the efficiency and power. The ceramic-metal adhesion, thermal/mechanical and thermal insulation properties were evaluated by SEM and dynamometer tests, presenting promissory results related to performance and efficiency of the combustion engine recovered to ceramic powder material.
