Q. Can you give some information about a cobalt sulfamate plating bath? M.F.
Featured Content
A. Cobalt and nickel are quite similar in many of their properties so you would expect the plating baths to be similar.
There is one difference cobalt dissolves with 100% efficiency without the use of chloride or bromides whereas nickel usually requires the presence of the anions to obtain efficient dissolution.
Following is a typical formulation for the bath. ?
| Component | Concentration |
| Cobalt sulfamate | 450 g/L |
| Formamide | 30 g/L |
| Total cobalt metal | 105 g/L |
| Parameter | Control Range |
| pH | 3–5 |
| Temperature | 20–50oC |
| Current density | 10–50 ASF |

Masking for Surface Finishing
Masking is employed in most any metal finishing operation where only a specifically defined area of the surface of a part must be exposed to a process. Conversely, masking may be employed on a surface where treatment is either not required or must be avoided. This article covers the many aspects of masking for metal finishing, including applications, methods and the various types of masking employed.
