SP4™ Extreme Wear Coating

SP4™ by Mustang Vacuum Systems is the Industry’s leading high wear coatings technology based on proprietary Hybrid DLC technology developed by our own Scientist and Engineers. SP4 (TM) represents our most advanced surface engineering capabilities to resist wear, lower friction, reduce scaling, reduce corrosion and extend the life-cycle of critical components in an almost unlimited range of applications. Our production scale equipment was designed, manufactured and installed by us to establish an affordable, high capacity coating services center capable of supporting high volume requirements for advanced coatings applications.

SP4 coating creates a surface that:

  • reduces friction
  • improve wear resistance
  • increases reliability
  • improves load capacity
  • reduces lifecycle part cost

SP4 provides:

  • excellent mechanical, electrical and thermal properties.
  • highest hardness for hydrogenated amorphous carbon coating
  • lowest co-efficient of friction
  • High resistance to acids and alkali attack
  • Biocompatibility

Automotive sector – Lower friction, higher wear/heat resistance, extend product life-cycle. SP4 coating has been race proven to perform significantly better than uncoated part.
Medical devices – High lubricity (non-stick), high wear resistance, biocompatible
Oil and gas – Excellent corrosion resistance in harsh environments, High wear resistance
Marine – Anti-biofouling and anti-scaling, corrosion resistance, hydrophobic
Firearms – Longer product lifespan (BCG), High hardness, high wear resistance, very high lubricity.


  • SP4 coating can be applied to parts of various size and geometry.
