Abstract
Copper-tin alloys are critical due to the excellent strength, corrosion resistance, and wide range of applications in engineering and manufacturing. However, it was a significant challenge to fabricate Cu-Sn coatings with uniform thickness and chemical composition in deep small blind holes. In this paper, a friction assisted jet electrodeposition with a variable diameter auxiliary anode was proposed. The profile of variable diameter anode was optimized by the validated multiphysics simulation. Experiments of jet electrodeposition and friction assisted jet electrodeposition (FJED) were conducted to fabricated samples. Results of characterizations showed that coatings prepared by FJED had uniform thickness and chemical composition. The hardness and adhesion were enhanced by removing hydrogen bubbles. All coatings exhibited an excellent corrosion resistance. The mechanism of FJED was revealed that the variable diameter anode improved the uniformity of coatings, and frictional brush enhanced the mechanical properties of coatings.
期刊介绍:
Electrochimica Acta is an international journal. It is intended for the publication of both original work and reviews in the field of electrochemistry. Electrochemistry should be interpreted to mean any of the research fields covered by the Divisions of the International Society of Electrochemistry listed below, as well as emerging scientific domains covered by ISE New Topics Committee.
