Abstract
Abstract Particles including a first material and having a first value of an intrinsic property such as thermal conductivity or coefficient of thermal expansion are coated, by a method such as electroless plating, electrolytic plating, sputtering, or spraying, with a second material having a second value of the intrinsic property in approximately the ratio of volume of coating to volume of each of the particles which makes the value of the intrinsic property of each of the coated particles equal to a desired value. The first and second materials can be metal or non-metal. A plurality of particles, including the coated particles, can be consolidated to form an article, or the particles and a matrix material can be co-deposited on a surface as a coating by a method such as electrolytic plating.
