Co–W films prepared from electroplating baths with different complexing agents

Abstract: The influence of different complexing agents with hydroxycarboxylic acid group on the electrodeposited Co-W thin films has been investigated. Comparison between the polarisation curves shows that the negative shift on the electrodeposition potential increased in the following order: no complexing agent, tartrate, malate, gluconate and citrate. The particular shapes of the jt transients indicate that a nucleation and growth process was involved for the Co-W electrodeposition in the presence of complexing agents… Show more

“…This type of electrodeposition is known as induced electrodeposition [3]. The interest in electrodeposited tungsten alloys with iron-group metals has increased in recent years due to their unique combination of anticorrosive [4], magnetic [5], and catalytic properties [6]. In addition, Co-W coatings are regarded as a suitable material for the defence industry, instead of hard chromium coatings deposited using hazardous hexavalent chromium baths [7,8].…”

“…W films are well-known for their outstanding properties. W imparts superior hardness and wear resistance to its layers, and W layers have improved corrosion resistance [2][3][4][5][6][7][8][9][10][11]. The application of Ag is interesting due to its low bulk resistivity (1.59 µΩ•cm) [12], relatively high melting point, and higher electromigration resistance compared to Cu, which is widely used in the downscaling of interconnects.…”

“…The replacing embraces processes where lubrication or dry friction conditions take place, for example in hydraulic equipment [2]. Citrate complexes were identified to be suitable for producing tungsten alloys by induced electrodeposition [3], also other types of electrolytes have also been found useful [4][5][6][7][8][9]. It is possible to obtained nanocrystalline or XRD-amorphous electrodeposits from such electrolytes.…”
