► Specification Requirements for Mil-C-26074E Classification
Nickel coatings shall be classified in accordance with thermal treatment applied subsequent to plating:
Class 1: As plated, no subsequent heat treatment: a bake for hydrogen embrittlement relief is not considered a heat treatment.
Class 2: Heat treated to obtain required hardness. May be used on all metals not affected by heating to 500F and above. Coatings shall have a minimum hardness of 800 knoop or equivalent vickers when tested. Class 2 coatings on steel parts that have a hardness of 40 RCH or above are required to be tested without cracking of fracture. The desired hardness can be achieved by heating the part (see within 4 hours arter coating).
Class 3: Aluminum alloys non heat-treatable, and beryllium alloys processed to improve adhesion of the nickel deposit. Non heat-treatable aluminum parts shall be heated for 1 to 1.5 hours at 375F to improve adhesion of nickel deposit.
Class 4: Aluminum alloys, heat-treatable, processed to improve adhesion of the nickel deposit. Heat-treatable aluminum alloys shall be heated between 240F to 260F for 1 to 1.5 hours to improve adhesion of nickel deposit.
* NOTE: These alloy types and grades may undergo microstructural changes when heated to 375F.
Nickel coatings have the following grades:
- Grade A - O.0010-inch minimum thickness.
- Grade B - 0.0005-inch minimum thickness.
- Grade C - 0.0015-inch minimum thickness
► ASTM B-733
A standard specification for autocatalytic nickel-phosphorus coatings on metals.
- Type 1: No requirement for phosphorus
- Type 2: 1-3% P low phosphorus
- Type 3: 2-4% P low-med. phosphorus
- Type 4: 5-9% P medium phosphorus
- Type 5: 10 % + P high phosphorus
QUALITY Requirements for ASTM B-733:
- Thickness - service condition;
- Adhesion - testing method ASTM B571;
- Composition - alloy type;

Physical Vapour Deposition (PVD) and Plasma Assisted Chemical Vapour Deposition (PACVD)
For in-depth information about the PVD and PACVD coationgs, please visit our sister company, PVD Advanced Technologies Inc.: www.pvdadvancedtech.com
A versatile, general-purpose coating for cutting, forming, injection molding, etc. Ideal for moderately abrasive applications.
A universal, high-performance coating for cutting, drilling, milling, reaming, turning and dry machining.
A high performance, aluminum coating with excellent heat resistance properties for dry machining applications.
A special, optimum release coating for forming tools for molds and dies and machine components. It is also very effective in piercing and punching applications.
A conventional carbon nitride coating for stamping, punching, forming, milling, tapping and interrupted cutting.
A multi purpose coating suitable for a wide range of applications including but not restricted to: milling, hobbing, tapping, stamping, punching, etc. Its properties include a low friction coefficient, combined with high toughness, hardness and heat resistance.
A unique coating for cutting, drilling, and milling machine components made out of aluminum or copper that protects against galling when working with soft metals.
Diamond-Like Carbon (DLC)
DLC coating is very resistant to abrasive and adhesive wear making it suitable for use in both rolling and sliding applications that experience extreme contact pressure. Unlike graphite, DLC provides high lubricity in both ambient and vacuum atmospheres.
Due to its unique combination of properties, DLC coatings are extremely effective in tribological and wear applications such as: magnetic storage media, molds, tools, dies, diesel injection pumps, sliding bearings, car valve rockers, gears, tappets of racing motorcycles, laser barcode scanner windows in supermarkets, VCR head drums, textile industry parts, motor cycle forks, razor blades, etc.

GOLD & SILVER PLATING
Silver plating is an electro-deposit process for electrical engineering and electronic applications. Unlike gold deposits, silver deposits tends to oxidize much easier, thus being often used as a less expensive alternative to gold.
This process is primarily for electric, electronic and wire bonding applications. It plates a thin, gold deposit on electroless nickel. Masking is available for plating a specific area, an internal or external thread, as required.
Its characteristics include:
- Very good solderability;
- A bright, uniform deposit; and
- It does not tarnish.
Silver plating is used for various applications in electrical, bearing surfaces, contacts, etc.
Its characteristics include:
- Excellent lubricity, ductility and solderability;
- A deposit density of 10.5 grams/cc;
- Hardness of 90-100 vickers;
- 99.9% pure silver; and
- Compliance with federal QQ-S-365, various AMS and individual company specification requirements.
