Abstract, An electroplating process is described for electroplating alloys of palladium and arsenic. The resulting electrodeposits are bright ductile and remain, ductile and crack-free even when the electrodeposits are quite thick. The deposits are quite hard and suitable for contact surfaces particularly in situations where wear characteristics require thick deposits. The electroplating process is also useful for making articles such as bellows by electroform procedures particularly since theelectroplated material has extraordinary physical properties (good resilience low, stress and ductility) as well as good corrosion resistance.

Why it's free to use
- Filed August 23, 1990. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended August 23, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 23, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
