3. Parameters influencing the nickel-boron coating process and the resulting deposits
In addition to chemical composition, electroless nickel deposition processes are influenced by numerous operating parameters that affect both productivity (deposition rate) and coating quality and properties.
3.1 Operating parameters
The deposition rate of nickel-boron coatings is generally considered to be a complex function of the various operating parameters, which must be finely tuned to ensure optimum, reproducible deposit quality and good bath stability.
