The electrical resistivities were measured in order to understand contact resistance differences. Electrical stability during and after environmental and mechanical tests was evaluated. Environmental tests included: Thermal aging at elevated temperature Battelle flowing mixed gas exposure Mechanical tests included: Formability Sliding wear Fretting Key attributes which were measured and reported included: Electrical resistivity Hardness Contact resistance Porosity level Coefficient of friction during sliding wear Fretting cycles to failure It was found that GFPdNi demonstrated lower electrical resistivity, higher hardness, lower initial contact resistance, lower coefficient of friction and greater durability during sliding wear. WE#1PdAg demonstrated acceptably low initial coefficient of friction, greater electrical stability during thermal aging and Battelle FMG exposure, better formability, and greater resistance to fretting wear.
