Preferential electrochemical etching of the metal grains or grain boundaries
We are using a cyanide based electrochemical etching process to etch tapered tips on a precious metal alloy wire and have discovered that each material lot behaves differently with the same etch process. These material lots will preferentially etch the grains in one lot and varying levels of the...- Spectre50
