Niplate® 600 SiC – Electroless Nickel-SiCSartoriadigitale2020-09-30T15:55:26+02:00
Electroless nickel SiC
Niplate 600 SiC is a composite medium phosphorus (5-9%) electroless nickel plating with silicon carbide grains (SiC) in 20-30% concentration.
Silicon carbide crystals ensure extremely high wear resistance which translates into a long working life in textile and motorsport applications.
Extreme hardness, up to 1100 HV
The ceramic particles of SiC and the hardening treatments performed after nickel plating permit increasing the hardness of the layer up to 1100 HV.
Very high wear resistance
Thanks to the tenacity of the electroless nickel matrix and to the extreme hardness of the ceramic particles of SiC, the Niplate 600 SiC coating has greater abrasive and adhesive wear resistance than that of hard chrome.
Uniform and constant thickness over the entire surface, including holes, ideal for precision mechanical engineering pieces with reduced tolerances.
Applicable on various metals
All the most common alloys used in mechanical engineering can be coated – iron, copper and aluminium alloys.
Niplate 600 SiC has a very high hardness, a combination of electroless nickel matrix and ultra-hard ceramic particles. This varies according to the hardening heat treatment performed after layer deposition.
Dehydrogenation 160-180°C x 4 hrs
Hardening 270-280°C x 8 hrs
Hardening 340°C x 4 hrs
Niplate 600 SiC has extreme abrasive and adhesive wear resistance, superior to that of hard chrome, thanks to the high content of ultra-hard silicon carbide particles.
Approximate wear value, TWI-CS10
A low number indicates a better performance – ASTM B733 X1 – Taber Abraser wear test – abrasive wheels CS 10 – load 1 kg
The corrosion protection of Niplate 600 SiC, assessed by means of salt mist test, depends on the base material, piece machining and finishing and the thickness of the applied coating.
Approximate corrosion resistance values
NSS according to ISO 9227 – Thickness 20 μm – corroded surface < 5%
For application where high chemical resistance is required Niplate 500 is recommended in place of Niplate 600 SiC. Niplate 600 SiC does in any case have good chemical resistance above all in alkaline environments.
Approximate values of compatibility with the coating environment only, they do not indicate corrosion protection of the base material. The overall performance of the coated piece depends to a large extent also on the type and quality of the base material. The actual resistance to the environment must in any case be tested in the field.
