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.

AddPlate® and NiPlate™ 201

A CORROSION RESISTANT, NON-MAGNETIC, LEAD AND CADMIUM FREE, HIGH PHOSPHOROUS ELECTROLESS NICKEL PLATING PROCESS
 

The 201 system is an economical, corrosion resistant, lead and cadmium free, high phosphorous electroless nickel process designed to deposit a uniform, nickel-phosphorous alloy onto a great variety of metals, alloys, and non-conductors.

The 200 system is available in two packaging options to best meet your needs. The NiPLATE™ option provides the greatest convenience to the user, while the ADDPLATE® option provides the greatest economy for shipping and use. Both options produce the same properties and quality.

  • The NiPLATE™ 201 option is supplied in three liquid concentrates: NiPLATE™ 201 A and 201 B are used for make-up, and NiPLATE™ 201 A and 201 C are used for replenishment.
  • The ADDPLATE® 201 option is supplied in two liquid concentrates: ADDPLATE® 201 M is used for bath make up with standard nickel sulfate and sodium hypophosphite commodities, and ADDPLATE® 201 R is used for replenishment of the bath with the same standard nickel sulfate and sodium hypophosphite commodities.

Some advantages of the 201 system are:

  • Corrosion resistance in acid environments
  • Neutral salt spray resistance of 1000 hours
  • A semi-bright deposit that will pass the nitric acid test
  • A pit free deposit of 5 mils or more
  • Excellent stability and bath life
  • Compressive stressed deposit
  • Non-magnetic properties
  • No lead or cadmium

The 201 system electroless nickel processes meet or exceed MIL-C-26074D and AMS 2404C.
