Diamond Coatings


Diamond coatings over the past few decades have gained a respectable amount of attention, due to their exotic mechanical, electrical, and optical properties. Typical benefits include:

Diamond Coating
  • Maximum surface hardness
  • Extremely low coefficient of friction (CoF)
  • Exceptional wear properties
  • Excellent dielectric material
  • High thermal conductivity
  • Optically transparent in IR wavelengths
  • many more…

Depending on the application, diamond coatings can offer the best solution for wide-variety of surface performance issues. Typical application enhancements include:

Diamond Coatings
  • Optical sensor protection
  • Increased transmission in the infrared spectra
  • Adjacent surface wear protection
  • Abrasion protection
  • Decreased coefficient of friction, leading to increased performance of gear systems
  • Galvanic corrosion and oxidation protection
  • many more…

What is SP3EC™ and how is it different from other diamond coatings on the market?

Since 2002, United Protective Technologies (UPT) has been developing a nano-composite thin-film diamond coating in conjunction with various branches of the United States Military. The coating has come to be known as, SP3EC™ or Surface Performance Enhancement Coating, which is precisely what it has been engineered to do. Originally discovered at the University of North Carolina at Charlotte (UNCC), SP3EC™ is a cutting edge coating that has proven to be one of the most advanced diamond coatings on the market today. Unlike other coatings in its class, SP3EC™ can be deposited at room temperature allowing the SP3EC™ coating process not to disrupt any of properties of the substrate. Also, another very unique quality of the SP3EC™ coating family is the ability for the coating to be deposited on a wide-range of substrates, from polymers to metals, without a ceramic interfacial layer. Many coatings currently on the market, are forced to use a non-carbon interfacial layer in order to adhere the coating to a substrate. While UPT can provide its films with a ceramic interfacial layer if required to meet your engineering specifications, UPT engineers have developed proprietary methods for achieving excellent film adhesion without their use.

Interfacial layers make the coating nearly impossible to remove, but SP3EC™ coatings can be easily removed from any and all substrates coated, creating one of the most advanced diamond coatings on the market today.

SP3EC™ coatings have proven to be an excellent solution for surface protection and increased performance in a wide range of applications. During the development of SP3EC™, several modifications of the coating have been developed for specific applications. Current variations of SP3EC™ include:

  • Optical Sensor Protection and Performance Enhancement
  • Wear/Friction Reduction
  • Galvanic Corrosion and Oxidation Protection
