Nanoscale Particles Enhanced Gold Plating
Using precious metals as plating materials is an effective measure to avoid failures of electrical contacts caused by fretting. When using precious metals, such as gold, one of the limitations to their lifetime is the wear resistance. In order to improve the wear resistance of gold plates, gold alloy is usually used. Instead of alloying elements, nanoscale particles of metal oxides were used for the modification of plates in our investigation. Some of the nanoscale particles show considerable impact on the performance of plates for electrical contacts. This paper shows the first results and new challenges when using nanoscale particles for electroplating.
