MANUFACTURE OF COMPOUNDED MATERIAL AS WELL AS HEAT RECEIVING MATERIAL AND MANUFACTURE OF HEAT RECEIVING MATERIAL

摘要

PURPOSE:To obtain a method for manufacturing a compounded material excellent in the bonding strength (adhesion) and heat conductivity of two materials and a method for manufacturing a heat receiving material. CONSTITUTION:In the method for manufacturing a compounded material obtd. by compounding a high melting point material and a low melting point material, a primary stage of forming pores in the high melting point material and obtaining a material having a distribution of porosity in which the porosity is high at least on a part of the surface and the porosity is gradually increased toward the above part and a secondary stage of infiltrating the material on the above low m.p. side from the part having high porosity in the material obtd. by the primary stage are contained, and the characteristic that the compositional ratio of the above high melting material to the low melting point material is slantingly distributed is marked.
