In duplex gold plating both hard and soft gold layers are plated in series to provide a net-reduced porosity gold deposit that could be provided with a single layer system. APT-PST™ is a post-plate process eeds a unique molecule into the microscopic gold pores providing greatly enhanced corrosion resistance and lubricity over untreated gold plating of a like thickness.

Haley explains that choosing an electrode material is often a result of where you were born and what type of EDM equipment you use. "For example, graphite was basically developed in the United States back in the early 1960s, so the American EDM equipment manufacturers in those days concentrated on the graphite circuitry when designing their equipment," he says.

Gold based neutron flux monitors may use gold foils. Au foils may be used to form a AuSn/Au joint system for opto-electronic chips. Modified gold foil electrode may be used to study heterogeneous electron transfer properties of biological electron transfer proteins.3 Electrodeposited polycrystalline palladium-nickel alloy on gold foils may be investigated for the enhanced alytic behavior of
The conformal insulator is realized using amorphous-SiC (a-SiC) which can be patterned to open windows to allow electrical conduction to occur between the electrode tips and the brain. Several generations of monolithic SiC devices have been fabried, tested and are reported in this dissertation.
To form SiC/Si heterostructures, we used a low-pressure chemical vapor deposition process to grow 280-nm-thick SiC nanofilms on a p-type low-doped (10 14 cm −3) Si substrate. In the in situ doping process, aluminum dopant was used in the form of a trimethylaluminum [(CH 3 ) 3 Al, TMAl] precursor.
