What chemicals are used in electroless nickel plating?
Electroless Nickel Plating (ENP) is the deposit of a nickel-alloy coating by chemical reduction – without the electric current that’s used in electroplating processes. The majority of ENP for engineering purposes is a nickel phosphorus deposit containing 2 to 14% phosphorus.
How do I check my plating?
Common and complex plating and other coating thickness applications are typically measured using one of the following test methods: X-ray fluorescence, coulometric, beta backscatter, magnetic induction, amplitude eddy current and phase-sensitive eddy current.
What color is ASTM B633 Type II?
Zinc Chromate Per ASTM B633-85 Type II Does the Type II in spec ASTM B633 [affil. link to spec at Techstreet] designate the color Zinc Yellow.
Which are advantages of electroless plating?
Advantages of Electroless Nickel Plating
- Excellent corrosion resistance.
- Excellent wear and abrasion resistance.
- Good ductility, lubricity and electrical properties.
- High hardness, especially when heat-treated.
- Good solderability.
- Even and uniform thickness even down deep bores and recesses, and at corners and edges.
What does 26074e stand for?
MIL-C-26074E, MILITARY SPECIFICATION: COATINGS, ELECTROLESS NICKEL REQUIREMENTS FOR (30 OCT 1990) [S/S BY MIL-DTL-32119 AND SAE-AMS-C-26074]., This specification covers the requirements for electroless (autocatalytic chemical reduction) deposition of nickel-phosphorous alloy coatings on metal and composite surfaces.
What does Mil dtl-26074 stand for?
This specification covers the requirements for medium and high phosphorous electroless (autocatalytic chemical reduction) deposition of nickel-phosphorous alloy coatings on metal and composite surfaces. This MIL Spec was briefly renumbered MIL-DTL-26074 before it was cancelled and replaced.
What is the replacement for the AMS-c-26074?
This MIL Spec was briefly renumbered MIL-DTL-26074 before it was cancelled and replaced. The two replacement documents were AMS-C-26074 and the classified (secret) MIL-DTL-32119. In the end, the AMS-C-26074 was withdrawn in favor of AMS-2404 and AMS-2433 after modifications were made to each to accommodate the government’s requirements.
