SECTION THROUGH AA 1000/2000 SERIES COATING Showing the top coating locked into the flame-sprayed metal reinforcing matrix. The loads are taken up by the reinforcement peaks and any wear that occurs exposes more of the top coating which is locked into the valleys. The peaks of reinforcement are continuously smeared with top coating and the end result is a smooth wear and abrasion resistant, release/low friction finish. TWO EXAMPLES FROM THE 3000 SERIES COATINGS The first shows a Nickel/P.T.F.E. composite coating which has excellent uniformity of deposition, especially suitable for complex parts. The Nickel/P.T.F.E. evenly dispersed throughout the Nickel at approximately 15% by volume. Any wear that occurs, exposes more P.T.F.E. which smears and lubricates to form a good low friction dry lubrication coating. The second example shows a top coating with the desired properties, overlaid onto a porous plated metal reinforcement. The metal reinforcement is chosen because of its extreme hardness. Curing at high temperature diffuses the top coating into the porous reinforcement, and subsequent high loads tend to burnish it in still further. Most suitable for dry lubrication at extreme loads/temperatures. SECTION THROUGH A 4000/5000 SERIES COATING This shows the top coating applied directly to the substrate. Coatings from these series are chosen for applications where load problems do not occur and where abrasion or mechanical damage need not be guarded against. N.B For the purposes of these simplified illustrations, all top coats have been shown in a single colour. However in practice many of the top coats are made up of two or more layers depending on the end properties required.
