2117195 9304806 PCTABS00020 The method of preparing metal-coated metals includes providing a metal powder and a disintegrator with a working chamber equipped with counter-rotating disks. At least one of said disks is made of a material softer than said metal powder. The metal powder is introduced into the working chamber and the disks of the disintegrator are counter-rotated so as to cause the metal powder to strike the disks, whereby the disk is eroded by the colliding metal particles and a coating of the eroded material is formed on the metal powder and the metal-coated metal particles are collected at the exit end of the disintegrator.
