High tech machinery and equipment in the military, aerospace, medical, nuclear, oilfield, and defense sectors require unimaginable engineering finesse. Metallic plating of parts is one thing that is absolutely necessary to keep cutting edge technology running like a well-oiled machine. Plating is done for a variety of reasons: mere decoration, gold or nickel plating give a nice reflective finish to otherwise drab industrial machinery; corrosion protection to ensure vital moving parts don’t get jammed up or seize due to corrosive impurities; improve solderability, so that welders can fuse all the parts into one functional machine; harden certain materials, such as glass to ensure that the parts can sustain the wear and tear of machine operation; reduce friction so as to decrease the possibility of damage through friction generated heat; improve paint adhesion so that paint can take to surface that usually don’t allow it, like glass; alter conductivity for those parts the function of which depends upon their electrical properties like resistance and conductivity; radiation shielding, for those parts which play a role in nuclear processes.
What types of metals are used in plating? Depending on function, metals such as cadmium, nickel, gold, and silver are used to plate machine parts. Cadmium connector plating is used on parts which need excellent corrosion resistance, galvanic compatibility with aluminum, or a frictionless surface.Cadmium can also be easily dyed to enable coherent colour coding of machine parts. Due to all these technical benefits, cadmium is used in aerospace engineering, military projects, and aviation innovation. Next time you take a flight you can now appreciate that it is cadmium connector plating which makes your aero-journey possible. Nickel connector plating is another common method of plating. Nickel has a mirror-like finish and is valuable for decorative purposes as well as functional ones. For its decorative quality, you can see nickel plating commonly on automotive products such as bumpers, mufflers, grills, rims, and trim. Among its technical advantages, nickel connector plating provides corrosion resistance, provides protection from wear and tear due to its hardness and frictionless attributes.
What are some specific uses of cadmium and nickel plating in certain industries? Cadmium plating is used in aerospace, where corrosion resistance is essential to keeping the structural integrity of the plane intact due to the low atmospheric pressure that planes and other aerospace vehicles often face. In the medical industry, too, cadmium is used to plate certain medical instruments due to its bacteria and mold resistance. For the machine complexities of the military and oilfield sectors, cadmium plating increases the conductivity of the parts that it coats, enabling new electrical engineering possibilities. Nickel plating, on the other hand, is often used in the production of electrical and computer parts as well as the telecommunications industry. It has excellent corrosion resistance, wear resistance, and increases the thickness of the parts that it coats.
All in all, there are benefits to plating your industry equipment no matter the service or sector you work in.
