BorAX - High Entropy Coating: The next big step in coating technology?
High entropy alloys are the current hype in metallurgy. The 5 or more components form alloys that have significantly better physical properties than conventional alloys. E.g.
- better strength / weight ratios,
- higher bending and tear strength and
- higher resistance to corrosion and oxidation.
Why should it be different with coatings The first results of the BorAX = Crn-AlCrTiN / BN / SiN layer prove this statement The continuous dosing of boron enables simultaneous high toughness with high hardness.
