Abstract
The present invention relates to a compound body consisting of a substrate with a surface coating of one or more dense, finegrained diamond layers, where the diamond grains are directly bonded to each other. Extreme hardness makes the compound body suitable for wear parts- and tools applications. Very good heat conductivity and an extremely high electrical isolation resistance makes the compound body extremely useful to lead away heat in electronic components.
