Boron Carbide (B4C) Thin Film Wear Resistant Coating

ThinFilm Coating Material

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.
  • 1-3 µm thickness
  • 4500 Vickers HK hardness
  • Coefficient of friction: less than 0.4
  • Operates at a maximum temperature 1000°C
  • Color: Gray/Black
  • Will outlast Titanium Nitride by 3X

This unique coating has been used to coat:

  • gun drills
  • sliding wear parts in oilfield industry
  • gears
  • cold heading dies
  • forging dies
  • injection molds
  • form tools
  • wear parts
