Zinc Plating ( 아연도금 )

Zinc coatings prevent oxidation of the protected metal by forming a barrier and by acting as a sacrificial anode if this barrier is damaged.

Hard Chromium Plating (경질크롬도금 )

Hard Chromium plating is a finishing treatment utilizing the electrolytic deposition of chromium.

Nickel electroplating (니켈전기도금 )

Nickel electroplating is a technique of electroplating a thin layer of nickel onto a metal object.

Electroless nickel plating ( 무전해 니켈도금 )

Electroless nickel plating (EN) is an auto-catalytic chemical technique used to deposit a layer of nickel-phosphorus or nickel-boron alloy on a solid workpiece, such as metal or plastic.
