Use one of the big aerospace industry for electroless nickel plating, more prominent application examples are: the middle of the Oklahoma Air Logistics, Northwest Airlines since 1979, and since 1983 have accepted the repair of electroless nickel plating skills gray machine engine parts. Pratt - Whitney JT8D jet engine has been discontinued, but so far there are still thousands of such an engine on the Boeing 727 and McDonnell Douglas DC-9 gray machine utilization, the reason is: a high-phosphorus, compressive stress The electroless nickel skills impeller for jet engine repair the JT8D six models to ensure that the re-use of this engine. Aero-engine turbine or compressor blades, usually nickel-phosphorus alloy electroless plating thickness is 25-75um, to guard gas corrupt, its fatigue strength low 25% less than chrome plating. Oklahoma City Air Logistics middle to accept the extra-thick layer chemical nickel-plated to fix gray machine parts, plated thick 275 750uM. Original acceptance of the plating process rework rate of 50% acceptance of the electroless nickel pass rate of more than 90%, we can see the obvious economic benefits. Funding on the gray machine generator (APU) after electroless nickel plating, life expectancy increased by 3 to 4 times. Up to 8.2 tons of the turbine engine main bearing surface by electroless nickel plating 100um, destruction of the vibration caused by the guard boot and shutdown.
    To reduce weight, the aviation industry extensive use of aluminum alloy by electroless nickel plating appearance not only enhanced corrosion resistance, abrasion resistance, and weldability, such as stroke engine piston head after electroless nickel plating to improve the use of life. Otherwise titanium parts, beryllium alloy parts are accepted low stress and compressive stress electroless plating nickel appearance cover pace.
    Nickel + thallium + boron ternary alloy electroless plating (NTB) is designated as Pratt - Whitney jet engine 160 parts looks hardening process, anti-scratch and fretting wear, such as: the NTB chemical plating jet engine shaft seal. U.S. Air Force requirements of engine manufacturers with 4000 tactical cycle, the wear volume 0.178mm, and so must be removed and rebuilt by the NTB electroless plating the spindle sealing surface wear significantly low wear by 4000 Tactical cycle after about 0.008 mm.
    The aerospace systems generally use the metal light microscopy, the matrix for high strength, light weight, beryllium or aluminum, nickel-plated appearance by special chemical strengthening, the phosphorus content of 12.2% to 12.7% of the electroless nickel can be polished to 9? high accuracy and so on, with outstanding performance in the necessary low inertia space.
    Chemical plating industry in China, despite a late start, but since the nineties through scientific research units unremitting happy, now has a mature technology and experience in Luoyang, China has been built the gray machine parts electroless plating nickel processing lines.
