Ion-plating and ion-beam mixing combination technology was employed to prepare surface alloys on copper tubes. Elements chosen for the purpose include Cr
Fe
Al
N
Bi
Sb
Sn
Se
and In. Experimental results of steam condensation on the external surface of the vertical copper tubes were obtained. The surface characteristics of the Cu-Cr and Cu-Fe alloy surfaces were analysed by using XPS
AES and AES-PRO of PHI-550 Multiple Function Electronic Spectroscopy. The mechanism for dropwise condensation formed on the new surfaces was presented.
