Abstract
A wear surface for helicopter shoes is constructed by forming a railed enclosure on a curved base plate, placing a mosaic of smooth-surfaced tungsten carbide blocks on the base plate within the enclosure, brazing the blocks to the plate and rails, and grinding the rails to form a smooth, edgeless transition between the wear surface and the plate surface.
