Features
The Chemical Ni process is applied in a (bass) drum and (static) frame system.
It is composed of an alloy of Ni and Phosphorus (6% to 14%), according to the requested characteristics for the coating (Corrosion and Hardness)
It is applied chemically, which allows a uniform distribution with the same thickness in all areas of the workpiece, even the most recondite (holes)
The coating is not porous so that its resistance to corrosion is very high.
It may be applied on any surface and/or material whether ferric or not.
A good coefficient of friction for the fixing elements may be obtained with the Chemical Teflon Nickel process that contains a high % of this element in the solution and therefore in the deposit.
The ductility for subsequent mechanical operations is medium-low and in the case of being necessary it is recommended not to exceed a thickness of 5 microns.
Corrosion resistance is very varied depending on the phosphorus content (% P) and the thickness of the coating.
Phosphorus content in excess of 10% and thicknesses larger than 20 microns ensure the best corrosion results.
The degree of hardness and resistance to friction and wear increases as you decrease the % in phosphorus of the coating.
Precision and distribution are excellent since it is a chemical finish providing maximum dispersions of 2 microns.
Applications for the following industries: electricity, electronics, automotive, moulds, mechanical, chemical, food, weapons, etc.
Respects European Directive 2003/EC/53 and RoHS.
NOTE: This is general information and is not in any case of a contractual nature since it needs to be confirmed by the conduction of tests and trials on each workpiece individually.
