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.
Contact STI for One-Plate® Electroless Nickel solutions, the simplest EN in the world. These One-Plate® systems use just one “Q” solution for both bath make-up and replenishment. This innovation by STI overcomes the many shortcomings of using three A, B, and C solutions. Available in low, medium, high phosphorous, and composite EN varieties. Naturally, all are RoHS compliant.”
NiSLIP™ 510 and 511
A COMPOSITE PTFE, MEDIUM PHOSPHOROUS, ELECTROLESS NICKEL PLATING PROCESS
The 510 system is a composite PTFE, mid-phosphorous, electroless nickel process designed to deposit a uniform composite with ultra-fine PTFE particles onto a great variety of metals, alloys, and non-conductors.
Some advantages of the 510 system are deposits with low coefficient of friction, self-lubricity, and excellent release properties; as well as corrosion resistance comparable to conventional electroless nickel.
The 510 system electroless nickel processes meet or exceed MIL-C-26074D and AMS 2404C.

NiSLIP™ 511 is a RoHS compatible version of NiSLIP™ 510.
NiSLIP™ 510 is a coating of submicron PTFE particles uniformly dispersed throughout a hard electroless nickel matrix. The percentage of PTFE in the coating is typically 20-25% by volume, but can be varied depending on the requirements of each application. The coating features a medium phosphorous (NiSLIP™ 510) electroless nickel matrix that is useful in most applications. In applications requiring even higher corrosion resistance, the high phosphorous version of this coating, NiSLIP™ 520, is recommended.
NiSLIP™ 510 provides numerous benefits including:
- Self-lubricity/low coefficient of friction
- Excellent release properties
- Outstanding corrosion resistance
- Perfect conformity to complex geometries
- Coverage of entire services or selected critical areas
- Applicability to many common metals, alloys, ceramics, and plastics
These features reduce sliding wear and sticking problems. The performance 
advantages of NiSLIP™ 510 have been utilized widely in the automotive, molding, textile, gear, and assembly industries to name just a few.
NiSLIP™ 510 has received a positive review from the U.S. Food and Drug Administration (FDA) Department of Health and Human Services. Click here for details.
