Abstract
In this paper, the internal stress and hardness of Ni–W alloy films with W contents in the range of 0–59 wt% were investigated. The amorphous Ni–W alloy films were electrodeposited with 59 wt% W content and the structure of crystalline alloy films was formed after heat treating. The experimental results showed that heat treating could prepare Ni–W alloy films with lower internal stress compared with low W content alloy films, and the heat treated alloy films still have high hardness. The internal stress and the hardness were about 230 MPa and 1000 Hv, respectively, when the heat treating temperature was 550°C. The relation of internal stress and hardness with the structure of alloy films is discussed.
