2. Salt spray test - Wikipedia

   en.wikipedia.org/wiki/Salt_spray_test

   The salt spray test (or salt fog test) is a standardized and popular corrosion test method, used to check corrosion resistance of materials and surface coatings.Usually, the materials to be tested are metallic (although stone, ceramics, and polymers may also be tested) and finished with a surface coating which is intended to provide a degree of corrosion protection to the underlying metal.

3. Chromate conversion coating - Wikipedia

   en.wikipedia.org/wiki/Chromate_conversion_coating

   For aluminum, the chromate conversion bath can be simply a solution of chromic acid. The process is rapid (1–5 min), requires a single ambient temperature process tank and associated rinse, and is relatively trouble free. [2] As of 1995, Henkel's Alodine 1200s commercial formula for aluminum consisted of 50-60% chromic anhydride CrO

4. Fretting - Wikipedia

   en.wikipedia.org/wiki/Fretting

   Fretting refers to wear and sometimes corrosion damage of loaded surfaces in contact while they encounter small oscillatory movements tangential to the surface. Fretting is caused by adhesion of contact surface asperities, which are subsequently broken again by the small movement. This breaking causes wear debris to be formed.

   A MIL-DTL-38999 circular connector plated with a nickel–teflon composite. Left: plug (male) type connector; Right: receptacle (female) type connector) Electrical or fiber-optic connectors used by U.S. Department of Defense were originally developed in the 1930s for severe aeronautical and tactical service applications, and the Type "AN" series set the standard for modern military circular ...

6. Conformal coating - Wikipedia

   en.wikipedia.org/wiki/Conformal_coating

   For example, in a chip-on-board assembly process, a silicon die is mounted on the board with an adhesive or soldering process, and then it is electrically connected by wire bonding, typically with 25.4 μm diameter gold or aluminum wire. The chip and the wire are delicate, so they are encapsulated in a version of the conformal coating called a ...

7. Expanded metal - Wikipedia

   en.wikipedia.org/wiki/Expanded_metal

   Expanded metal is frequently used to make fences, walkways, and grates, as the material is very durable and strong, unlike lighter and less expensive [dubious – discuss] wire mesh. The many small openings in the material allow flow through of air, water, and light, while still providing a mechanical barrier to larger objects.

9. Wire wrap - Wikipedia

   en.wikipedia.org/wiki/Wire_wrap

   The sockets have square posts. The usual posts are 0.025 in (0.64 mm) square, 1 in (25.4 mm) high, and spaced at 0.1 in (2.54 mm) intervals. Premium posts are hard-drawn beryllium copper alloy plated with a 0.000025 in (630 nm) of gold to prevent corrosion. Less-expensive posts are bronze with tin plating.
