we call rust, this rust comes off from the surfaces as flakes of crumbling solids eventually eating away all of the metal. This process is further catalysed by impurities like acidic gases present in the air surrounding the machinery. In industries where even slight air-borne contaminants can incur extreme losses, it’s important to employ corrosion control methods at this micro level. Because it takes little corrosion to impact some of the micro-miniature devices that are used in electronic applications.
