Does the cermet layer build up on non-ferrous metals?
Yes, a cermet layer is formed on all metal-metal friction pairs, including non-ferrous metals and alloys. For example, when dismantling an internal combustion engine, one can see that a cermet layer has been formed both on the inner surfaces of the cylinder, and on the acting surface of the crankshaft bearing bushing made from an aluminium alloy. In full compliance with the theory, a thicker layer has been formed in locations with heavier wear out. When revitalizing worm reduction gearboxes, the cermet layer is formed both on the worm acting surface, and on the teeth of the worm wheel, which is usually made of a non-ferrous metal like bronze.
