Latest Patents

Harold E Marker holds a patent for "Superplastic alloys formed by electrodeposition." This patent describes a method for forming superplastic alloys by depositing the alloy onto a cathode from an electrolyte containing specific metal ions. The resulting products are fine-grain deposits that are free of intergranular embrittling films. These alloys exhibit grain boundary flow at superplastic temperatures below the recrystallization temperature of the deposit. Nickel-cobalt alloys are preferred in this process, which utilizes halide-free sulfamate baths to ensure high-quality deposits.
