Abstract
A method for coating of a first substrate with a first diffusion bond layer by deposition of a first material which forms the first diffusion bond layer on a first surface of the first substrate such that the first diffusion bond layer forms a grain surface with an average grain diameter H parallel to the first surface smaller than 1 μm. The invention further relates to a method for bonding of a first substrate which has been coated as described above to a second substrate which has a second diffusion bond layer, the method of the bonding comprising the following steps: bring a first diffusion bond layer of a first substrate into contact with a second diffusion bond layer of a second substrate, pressing the substrates together to form a permanent metal diffusion bond between the first and second substrates.
