Electroless Nickel Plating

Electroless Nickel is a functional finish which is capable of offering enormous advantages to the engineering field. The process offers several advantages over conventional plating processes. Among these are uniform deposit build-up on all surfaces without beading; the ability to plate irregular shapes uniformly; and the ability to heat treat the deposit to increase the hardness to 68 Rockwell C.

Corrosion Resistance:
Compared with an electro-nickel or chrome deposit of the same thickness, the corrosion resistance of "Electroless Nickel" is vastly superior in an extensive range of environments. The deposit has very high inherent corrosion resistance and low purosity.

Hardness:
46-48 RC as applied but can be heat treated to bring the hardness up to 68 RC.

Abrasion And Wear:
The abrasion resistance of Electroless Nickel deposits in the as-plated condition is superior to electrolytic nickel and is equal to that of chrome after heat treating

Thickness:
"Electroless Nickel" can be applied from .000050" to .003" thick with a very uniform coverage.

Specifications:
"Electroless Nickel" conforms to MIL-C-26074E, AMS 2404, and AMS 2405.

Substrates:
"Electroless Nickel" can be applied to Stainless Steel, Copper, Berylleum, Nickel and its alloys, Aluminium, and all steels.

Hard Chrome

Abrasion, friction, corrosion, heat and vibration are the most frequent causes of wear. Chromium plating resists the effects of these elements, by interposing a super hard, anti-friction, rust resistant layer between exposed surfaces, mating surfaces, and their surrounding parts.

Hardness:
Chromium is 68-70 Rockwell C as applied.

Corrosion Resistance:
Chromium is highly resistant against corrosive attack by water, salt solutions, and most chemicals. Its behavior in corrosive service is closely related to that of Stainless Steels.

Thickness:
Chrome can be applied from .000050" to .010" thick. Coating thicker than .002" will need to be ground after plating.

Specifications:
QQC-320B and AMS 2406

Substrates:
Chrome can be applied to most ferrous and non ferrous metals

Copper Plating
Copper plating has been very successful as a permanent coating to eliminate thread galling when similar exotic metals are assembled. The copper coating also increases the electronic conductability of mating parts.

Zinc Phosphate
A phosphate coating that absorbs and holds lubricating oils. The coating properly sealed and oiled provides good corrosion protection during storage.

Specification:
MIL-P-1623F

Electrolytic Nickel
Very good corrosion protective coating used largely in the electronics field.
Specification: QQN-290

Decorative Nickel Chrome
A good corrosion resistant coating used mainly as a decorative finish.

Specifications:
QQ-N-290 and QQ-C-320B

Wet And Dry Blasting
Vapor honing, glass bead, aluminum oxide, and sand.
