DEMARTIN electroless nickel SiC
Chemical nickel coatings offer first-class protection against corrosion and wear. The electroless nickel coating makes the surface robust and durable, with a uniform coating thickness, even with more complex factory moulds.
Dispersion coatings with silicon carbide inclusions serve as wear protection coatings and to improve properties in terms of tribology.
Coating with extremely good abrasion resistance high matrix hardness of up to 1,000 HV good corrosion protection behaviour silicon carbide grain diameter of 0.001-0.002mm. Has a low coefficient of friction and scores points for its resistance to chemical stress.
Temperature resistance up to 500°C and true-to-size deposition of +/- 5-8% layer thickness tolerance
