In this paper results of the alloying of magnesium materials by a combination of thermal spraying and a subsequent electron beam surface technology are presented. The objective is to improve the wear resistance of magnesium alloys. Aluminium and copper were chosen as the alloying material. These metals can form hard intermetallic compounds with magnesium, such as MgAl2 or Mg2Cu. The vacuum plasma spraying is well suited for the deposition of these additives because of the prevention of their oxidation. Besides, the EB technology take place under vacuum conditions, and the reactions between magnesium and oxygen are prevented. Paper text in German.
