A. Hi, Syedu. Electroless nickel plating, especially high-phosphorous electroless nickel should do it easily. Gold plating would do it. Zinc alloy plating with a high quality proprietary chromate and topcoat can probably do it. Unfortunately, you probably need to consider a number of properties to select the type of plating; you probably can't pick a plating material from a single parameter, let alone an artificial one like salt spray resistance. Good luck.
