NEDOX® is a surface treatment method to be used on steel, stainless steel, cast iron, copper and copper alloys. The process combines the properties of electroless nickel and coating with fluorocarbons resulting in a number of improved properties:
- High Hardness
- High wear resistance
- High corrosion resistance
- non galling properties
- Low cofficient of friction
- Non-stick properties
- Close dimensions
- Uniform coating/
- No post machining
There are variorus coating withhin the NEDOX® family, all featuring the combiination of properties but each of them optimised to one, or some, of them:
Highest hardness and wear resistance in combination with best corrosion resistence, low coefficient of friction and non-stick properties, Approved for use in contact with fod and drugs.
Good corrosion resistance, hardness and wear resistance in combination with low coefficient of friction.
High hardness and wear resistance in combination with low coefficient of friction.
Best non-stick properties, especially against rubber and urethane, and at heat welding of plastics. Approved for use in contact with food and drugs.
Best dry lubrication, lowest cofficient of friction, by a combination of MoS2 / PTEE Together with high hardness and wear resistance.
* The flourocarbons used in the process are approved for the use in food and drug industry by the US Food & Drug Administration and the USDA.
Basic coating build-up for the NEDOX® coating is an electroless nickel coating process. The term “electroless process” is used to describe methods of plating by means of chemical reduction instead of using current as in electroplating. The reducing agent used is sodium hypophosphite which results in a conntent of 9-12% of phosphorus in the produced coatings. This gives the coating a number of intersting properties. By combining thes with different types of treatment with flourocarbons NEDOX® coatings ends up with additional improved properties and positive synergistic effects.
