NICKEL ALLOY
Nickel and nickel-based alloys possess effective resistance to a wide range of corrosive environments , in many cases, some materials such as stainless steel or super stainless steel are unable to resist these corrosive conditions. Nickel itself is a very versatile corrosion-resistant material, while as an alloying element, in a large composition range, nickel possesses Metallurgical compatibility with the other metals ,can be composed of a number of binary and ternary alloys and other complex alloys system,nickel-based alloys have a unique corrosion resistance and high temperature corrosion resistance.to deal with the corrosion problems that include chemical,petrochemical, marine, paper, agricultural chemicals, oil and gas, energy conversion and many other industrial environments. In this artical, the corrosion resistance in aqueous solution of nickel and Part of the nickel-base alloys was discussed.
