Creator of Composite Diamond Coating®

Surface Technology, Inc. is the creator and technical leader of CDC - Composite Diamond Coating®, an exceptionally engineered coating of electroless nickel with fine diamond. The synergy of these materials makes CDC an exceptionally hard and wear resistant coating. CDC conforms to even the most complex geometries and is an excellent replacement for chrome plating. STI makes CDC available via coating services from its production facility as well as chemical products sold directly, through a network of distributors, and by agreement with licensees worldwide.

Electroless Nickel Plating Systems

Electroless Nickel (EN) is a chemical method for plating nickel alloys onto metal parts. The alloy can be formed with varying percentages of phosphorus or boron to provide a wide range of hardness, corrosion resistance, magnetism, appearance and other properties. The process uses no electricity, EN coatings are perfectly uniform thickness across even the most complex shaped parts. EN plating can be applied to virtually any substrate material with the most common being steel, stainless steel, aluminum, copper alloys, titanium, and even plastics.

Surface Technology Inc. is both:
 

Since the 1950s, EN has been used on a global industrial scale. Since then, the plating industry has traditionally utilized EN systems consisting of three chemical solutions (typically called A, B, and C). STI has now revolutionized the way EN is made with the introduction of One-Plate® EN solutions. What makes One-Plate® so superior to all other EN is that One-Plate® systems only need one single component (Q) to make up and replenish the EN bath, not three. There are One-Plate® solutions for low, medium, and high phosphorous EN.

By using just one component, One-Plate® systems provide the following advantages over old-fashioned three component systems:
 

  • UnPrecedented ease-of-use
  • Consistent Quality
  • Increased Productivity
  • Simplified Logistics & Storage
  • Longer Bath Life
  • Environmental Benefits


The following are the One-Plate® systems and their properties to meet all your EN needs:

Stress Slightly Tensile Slightly Compressive Compressive
Magnetic Properties Slightly Magnetic Non-magnetic Magnetic
Self-maintaining pH YES Partially Partially
 

Another exciting benefit of STI's One-Plate® systems is that our composite dispersions may be added to the above baths to produce EN coatings with particles such as:
 

These materials can enhance or add new properties to the EN coatings such as higher friction and grip, lower friction and release, increased hardness, greater wear resistance, and many more.
