Keywords: | Tungsten oxide; Reactive sputtering; Mechanical properties; Tribology | Issue Date: | 2007 | Citation: | Vacuum. 81:11-12 (2007) 1426-1429 | Abstract: | In this study, tungsten oxide coatings with 13 and 75 at% of oxygen were prepared by DC reactive magnetron sputtering from a pure W target in an Ar+O2 atmosphere. The coating hardness (H) decreased with increasing oxygen content from 25 to 7.7 GPa. The values of H/E ratio were 0.08 and 0.07 for W87O13 and W25O75, respectively. | URI: | https://hdl.handle.net/10316/4200 | DOI: | 10.1016/j.vacuum.2007.04.001 | Rights: | openAccess |
