Electropolishing and etching systems utilize controlled electrochemical and chemical processes to enhance sample surface quality and reveal microstructures. Electropolishing removes microscopic surface layers to produce smooth, reflective finishes by applying regulated voltage and current in electrolyte solutions. Etching uses precise chemical reagents to selectively highlight grain boundaries and phases without mechanical damage. These systems provide adjustable parameters including voltage, current density, temperature, and timing to optimize metallographic anal...
