How Coatings Are Used

• Jet engine compressor blades erode in service as a result of abrasive particles impinging at high speed.  A .002"-.004" thickness of Tungsten Carbide/Cobalt solves the problem up to 800 degrees Fahrenheit, a Chromium Carbide Cermet up to 1,600 degrees Fahrenheit.

• Power generation plants experience  significant oxidation damage on combustor components at temperatures up to 2,200 degrees Fahrenheit.  A Yttria Stabilized Zirconia thermal barrier solves the problem.  Parts are in service three times as long as non-coated components.

• Brake discs on bicycles prematurely wear the aluminum rims.  A coating is designed to mate well against the disc, prevent the wear and allow economical application. Problem is solved.

• Drive Rollers in commercial printers and plotters must be ´rough´ enough to drive the paper.  The ´roughness´ must be ´rounded´ so that sharp peaks do not tear the paper, and it must stay ´rough´ when run against the very abrasive paper.  A Tungsten Carbide coating is designed that lasts for years of service.

• A very high purity ceramic with specific electrical properties is required in chip manufacturing.  A coating with impurities restricted to parts per billion applied to thousands of components.

• EMI Shielding is required at low cost for plastic components in automobile ignitions.  A Zinc coating and the tooling required for hundreds of thousands of parts is produced in weeks.

• Titanium Gimbals for advanced aircraft require wear resistance on bearing surfaces, very fine surface finishes, tolerance to .0005" and minimal fatigue effect on the titanium.  An HVOF Tungsten Carbide is applied, finished ground to 8RMS and shipped by the hundreds on schedule.
