Boron Carbide (B4C) Thin Film Coating is a very wear resistant coating. It is applied < 250F at 1.5-3 microns thick. It is a great solution when a hard, ultra lubricious coating is needed.
Key Benefits and Uses of Boron Carbide PVD Coating:
-
B4C prevents galling in wear components, forming, punching, and stamping applications.
-
B4C is extremely hard and its adherence is as strong as the base material itself.
-
B4C provides constant lubrication right where it’s needed when it’s needed. In fact, B4C has a wicking property where oil is attracted to the coating.
-
Will not alter the surface finish after the part has been coated. A polished finish stays polished!
-
Will not affect the metallurgy of the part. Will not anneal like a CVD coating will.
