Design engineers are taking a close look at ceramic-teflon coatings in light of a growing demand for part and product reliability, longer life and reduced component costs. The ultra-hard structure of a ceramic combined with the lowest coefficient of friction in the industry provides the ideal wearing surface. Today, ceramic-teflon coatings are turning up in critical applications as ultra-reliable seals, couplers, bushings, guides, pistons and many other components in the chemical, petroleum, and other industries.
Up to 12 on the MOHS scale. Only diamond is harder. Stainless steels average 8.
Ceramic coatings are recommended for resistance to wear by abrasive grains, hard surfaces, particle erosion, and cavitation, at all temperatures below 1,000 deg. F. These coatings also have excellent self-mating and anti-galling properties
Conductivity is 1/10 of brass. For the mechanical engineer, they are thermal insulators, retaining or excluding heat.
Ceramic coatings are insoluble in acids, alkalis and alcohol.
The lowest static and dynamic coefficient of friction of any solid material.
Coating applications are found in industries such as air transportation, motor vehicles, pumps, compressors, machine tools, steel production, pulp and paper mills, electric production and many others.
Most common applications are pump sleeves, machine spindles, sealing surfaces on production equipment, wire drawing equipment, pump plungers, mechanical seals, wear rings, cylinder liners, exhaust fans, hydraulic brakes, palm guides, oil distributor shafts, water turbine buckets, recording heads, polishing fixtures, printing rolls, pump impellers, valve seats, sealing caps and flanges.
