Metal tarnish , oxidation & electroplationg

Singapore atmosphere that causes oxidation & tarnish to metal Singapore is surrounded by the sea & where the atmosphere contains salt , sulphuret ,moisture, air, acids ,which causes many metals to oxidize , tarnish & rust that are chemically active elements . The problem with iron as well as many other metals is that oxidation takes place and the oxide formed does not firmly adhere to the surface of the metal causing it to flake off easily. This eventually causes structural weakness and disintegration of the metal.When a metal is attacked by substances around it, it is said to corrode and this process is called corrosion which causes deterioration of essential properties in a material. All metals are subject to oxidization & it the natural process of the metal returning to its base elements by combining with oxygen from the local atmosphere which frequently causes pitting in metals that use an oxide layer to protect themselves. Metals such as stainless steel tend to pit in seawater if the mechanism that maintains the film breaks down for any reason. This also happens to copper , brass , bronze artifacts when exposed to air and water, it slowly get tarnished by acquiring a thin green oxide layer. Similarly, silver quickly acquires a thin black oxide coating in moist air. & even the heaviest metal lead also tarnishes in moist weather. The black coating on silver and the green coating on copper are examples of corrosion in which the oxides formed strongly bond to the surface of the metal, preventing the surface from further exposure to oxygen and consequently slowing down corrosion. The only solutions against these is to get your metal items protected & rejuvenates the color and luster on faded, dull metal by applying protective coating that will protect it from the damages the sun, salt air, acid rain & moisture without the effort of weekly polishing
