| NYE-CARB®
is a licensed process for depositing extremely hard non-metallic
particles in a nickel alloy matrix. The particles are very
small and quiet uniform in size. The standard NYE-CARB®
coating contains 15-20% silicon carbide particles by volume.
Particle sizes range from 1-3 microns. The matrix material
is an alloy, which is 90-93% nickel, and 7-10% phosphorus.
The NYE-CARB® process coating is primarily used for
wear resistance because of the extreme hardness of the silicon
carbide particles. This includes surface exposed to metal-to-metal
rubbing. The nickel alloy, which provides a matrix for the
composite, is one of the most outstanding corrosion-resistance
coatings available. It is used as a substitute for stainless
steel in some applications.
Since the composite is so hard and so resistant to wear
and abrasion, it follows that it must be also very difficult
to grind, hone, or lap. And so it is. The process,
however, is so uniform in application that size can be held
as accurately as good grind. This applies to virtually any
geometric configuration. Sharp corners remain sharp with
no edge built-up. Recesses and blind holes are uniformly
coated. Thru-holes and bores remain straight and untapered.
UNIFORMITY
Uniformity of thickness to within +/- 10% with no deviation
caused by surface configuration.
ABRASION AND WEAR RESISTANCE
Abrasion and wear resistance through a combination of high
hardness and low coefficient of friction.
SMOOTH
A smooth, metallic, unblemished surface that can be polished
to optical standards.
CORROSION RESISTANCE
Corrosion resistance due to the low porosity and non-crystalline
structure.
EXCELLENT ADHESION
Excellent adhesion resulting from the chemical bonding
of the coating.
