Located in Chesterfield, UK, NiTec undertakes the coating of components ranging from a few centimetres in size to many metres using a patented Ni-P coating of high corrosion resistance and hardness, deposited by galvanic action.THE phenomenon of galvanic action which occurs when two dissimilar metals are present in a common conducting liquid - such as acid rain - can be put to good or bad use. The sacrificial nature of zinc in protecting a steel substrate is an example of a benefit, whereas the accelerated rusting of nails in tanalised wood -which contains a copper salt to destroy fungal growth - is a negative result caused by copper plating out on steel nails and corroding the nail.Electroless nickel plating is, however, a beneficial example of a galvanic reaction allowing a hard and corrosion resistant coating to be plated onto a less noble substrate without the need to apply an electric current. The process was developed in 1952 in USA and is now licensed for use globally.
