Question

Why should we have to deposit Nickel
​

Answer 1

Answer:

The deposits are used in various engineering applications to enhance surface properties, such as hardness, corrosion and wear resistance, and magnetic properties. For example, turbine blade manufacturing in the aerospace industry uses electroplated nickel to prevent surface oxidation during high temperature forging.

Answer 2

Answer:

because these are resistant to dry air

Explanation:

Nickel coatings are resistant to dry gases, such as carbon dioxide, hydrogen, ammonia. They are also resistant to carbon tetrachloride, oil, soaps and petrol. Nickel coating increases fatigue strength. Nickel coatings also minimize corrosion fatigue. Nickel coatings are not resistant to nitric acid and environments containing chloride
