Estimating the term…
The present invention relates to a method of producing a functionally grant material whose components and structure are continuously adjusted by the coating, plating and powder metallurgy techniques to change its function in turn and provide a method of producing a functionally gradient material superior in heat-resistance, corrosion-resistance and resistance to thermal fatigue by distributing a third component having a lower Young's modulus or formed of high-strength material sufficiently durable to the fracture strength among ceramics as a first component and metals or other ceramics as a second component to change the function.
A method of producing a functionally gradient material, in which a composite material, in which an intermediate layer with a continuously changing ratio of a second component to a first component is arranged between a ceramics as said first component and a metal or another ceramics as said second component, is produced, characterized in that a component having a lower Young's modulus or a high-strength material as a third component is distributed in said intermediate layer.
