| Abstract: |
| Iron-tungsten amorphous alloy was electroplated on the steel by electroplating. The regular of appearance, component and structure were investigated by SEM, EDS and XRD, respectively. The current efficiency of cathode, thickness of electroplated coatings and microhardness at different current densities were obtained. Subsequently, the grain and piercing became greater when the current density increased, and these piercings were much more, meanwhile the content of tungsten, current efficiency of cathode were slightly dropped. It was found that the thickness of electroplated coatings was increased with current density but the microhardness was reverse. Moreover we also discussed the reason of these changes. |
