摘要: Pure Ti and Ti-Cr films of various Cr content (<40 at.% Cr) were prepared on the surface of aluminum alloy by using DC magnetron sputtering. Ti-Cr alloy films exhibited a bcc structure (beta phase) stabilized with Cr addition. Pure Ti and Ti-Cr alloy films displayed (002) and (110) preferred orientations, respectively. The denser morphologies and finer grains were achieved for Ti-Cr films with increasing the Cr content. Compared with that of pure alpha-Ti film, Ti-Cr films (beta type) showed remarkable increase in hardness (similar to 6.0 GPa). The further increasing Cr content (>10 at.% Cr) slightly changed the hardness and elastic modulus of Ti-Cr films with beta structure. The analysis of HE ratio (H-3/E(2)and H/E) indicated the better plastic and wear resistance of Ti-Cr films than that of pure Ti films. (C) 2017 Elsevier B.V. All rights reserved.
