Coatings are hard with good corrosion resistance in acidic media and good oxidation resistance in air up to relatively high temperatures. Coatings exhibit excellent galling and wear resistance and even resist fretting with inadequate lubrication. Excellent tribological performance when rubbing against itself, stainless steel, gray cast iron, aluminum, superalloys and hard chromium plated surfaces. Applications include pump components, gas turbine applications to combat fretting, landing gears, ball and roller bearings, sleeve bearings, journal bearings, piston rings, camshafts, high and low pressure nozzles, valve seats, valve faces and exhaust fan blades.
Store in the original container in a dry location; Open containers should be stored in a drying oven below 38°C (100 °F) to prevent moisture pickup; Tumble contents prior to use to prevent segregation.
Metco 4800 can be applied by either HVOF or atmospheric plasma spray. It has a tightly controlled, tailored particle size distribution that offers a unique alternative to the other products discussed above. It is recommended as the preferred choice for new coating applications. For oxidation temperatures, up to 980 °C (1800 °F), Metco 4800 is one of the best choices because of its high chromium content. All of the Cobalt Molybdenum Chromium Silicon Tribaloy Alloy Powders offer good corrosion resistance in most acidic and saline environments; however, for the best corrosion resistance in these environments with better as-sprayed wear resistance, choose Metco 4800, Diamalloy 3001 or Metco 68F-NS-1.
