Copper sulfide (CuxS) has been frequently observed in steel samples, prepared using selective potentiostatic etching by electrolytic dissolution (SPEED). It is often the case that CuxS is detected unexpectedly from the precipitates extracted from steel samples by selective potentiostatic etching, al...
