1977-05-03· Tin-nickel alloy plating is one of the tin alloys that has been used and that is superior in its anti-corrosive characteristics compared to a plating of tin or nickel alone. The tin-nickel alloy plating shows a reddish appearance. To carry out the tin-nickel alloy plating, an acidic fluoride bath is generally used, and the electroplated layer thus formed is very brittle and is apt to crack ...

Surface Coating Technologies - Electrical Contacts

Electroless plating is defined as a coating process which is performed without the use of an external current source. It allows a uniform metal coating independent of the geometrical shape of the parts to be coated. Because of the very good dispersion capability of the used electrolytes also cavities and the inside of drilled holes in parts can be coated for example. In principal two different ...
