The surface finishing serves as a guarantee of electromagnetic compatibility (EMC), corrosion and wear protection and the prevention of deposits (isolating effect).
In aerospace technology, surfaces of certain components or component groups are coated with electroless nickel. The surface finishing process
serves:
To guarantee electromagnetic compatibility (EMC).
As a protection against corrosion.
To prevent the forming of build-up (insulation effect). As a protection against wear.
When solid lubricants such as PTFE (Teflon) and bornite are incorporated in nickel matrix (electroless nickel dispersion coatings), the process can also be used for sliding coatings (coefficient of friction< 0.1). The dry lubricant coatings thus produced have a temperature resistance of up to 295°C for electroless nickel PTFE and up to 670°C for electroless nickel bornite.
