Surfaces are then converted to silicon carbide in a cost-effective manner. The siliconized surface provides increased abrasion resistance when compared to metallic options. As some residual graphite remains within the silicon carbide matrix, the resulting topography enables better lubriion to the interface, extending load capabilities.
