ZK60 Mg alloy was treated by high current pulsed electron beam (HCPEB) so as to improve the wear resistance. Surface SEM images show that the HCPEB bombardment caused surface melting
grain boundary elimination and uniform distribution of the metal compositions. SEM image of the cross-section microstructure indicates that a remelted layer of 5–11 μm was formed on surface of the HCPEB-treated ZK60 Mg alloy. Wear test shows that wear resistance of the treated ZK60 Mg alloy after 23 keV 15-pulse treatment was improved by a factor of 2.5.
