method for formation of disks in binary alloy

摘要

it is a method for forming a preforma having an inner part of a first metal and a second metal part outside.the preforma is manufactured by spray process for training.the initial phase of training, spray is performed with a first metal in a crucible distributor that provides a current of the first metal to a small area where the current romeps in many droplets which are driven by a gas atomizzatore on a receiving surface.the second phase of the process involves the addition of small quantities of a second metal in the crucible gas station before the first metal is completely downloaded from this to enableand a mixing of the two metals are to be formed on the preforma between an inner part and an outer part of the same.the third phase of the method is the addition of a second metal in the crucible distributor so that the last stage of training to pruzzo is performed with the second metal and, consequently,the outer parts of the preforma are formed by the second metal. between the interior and exterior of the preforma form a metallic bond desiderabilmente good.
