Why can't we Ni-Cr plate at room temperature?




Hello..

I want to know if it is possible to do Ni-Cr plating at temperature of plating bath near to room temp (25 c) by any method. What is idle temp. of Ni plating bath and mechanism behind heating the bath to get fine plating results.

If it is compulsory to heat the bath then please tell about latest and economical options to heat the bath and conserve the heat during cold winter nights used commercially in modern plating industry.

We plate at high currentdensities and get burns on articles if bath is not very hot.

Please Help.

It never ceases to amaze me the number of people that try to go into plating without the most minimal of reference material, IE: books, research papers, seminars and operations sheets for proprietary processes. You have found out the exact reasons why some plating baths require a higher temperature - They burn or nodule plate or do not have coverage. Probably the absolute minimum book that you need is the plating guide book available from the folks that publish Metal Finishing. Normally it comes with a 1 year subscription to metal finishing, but you might be able to get a stray copy from someone.

Temperatures of 55 centigrade are essential for both brightness and leveling, by permitting better conductivity of the solution to the passage of current.

Viable plating ops require high temps. Parts are guaranteed to burn at lower temperatures. Jacketing of the bath and a lid are thermal conservation methods.Electricity, Gas and oil fired burners are commonly used for heating. Titanium coils are employed to convey heat.

Did I answer your questions?
