Tungsten carbide coatings applied with high velocity oxygen fuel hvof involve a high kinetic energy being sent into the powder particles as a thermal.
Tungsten carbide coating thickness.
Carbide coatings wear resistant hard facing materials typical thickness of 0 1 to 0 5mm extremely hard coating materials 65 72 rc 900 1300hv.
A a coatings plasma sprayed tungsten carbide was designed for use in thin coatings not more than 5mm 020 thick.
Wc is a chemical compound specifically a carbide containing equal parts of tungsten and carbon atoms.
We offer coating formulation options mainly tungsten carbide c1000 c1000ni c9000 and chromium carbide c4000.
Tungsten carbide chemical formula.
Most standard wear resistant alloys contain a maximum of 35 by volume of softer chromium carbide.
The use of d gun thermal spray for carbide coatings leads to a strong bong strength with options for thickness and roughness to provide the proper corrosion wear and erosion protection.
The coating thickness varies based on the size of the part but is between 0 5mm to 3mm with a hardness of 91 hra and a mirror polish to keep friction at a minimum.
If sprayed thicker the probability of cracking and delamination will increase rapidly as is the case of thick coatings of all fine powders.
Tungsten carbide with a vickers number of 1700 2400 85 hrc equivalent is composed of 90 carbide particles by weight 80 by volume.
In its most basic form tungsten carbide is a fine gray powder but it can be pressed and formed into shapes through a process called sintering for use in industrial machinery cutting tools abrasives armor piercing shells and jewellery.
A a coatings hvof sprayed tungsten carbide was designed for use in thin coatings not more than 5mm 025 thick.
