ABSTRACT:
A refiner plate has bars integrally formed with the refiner plate base member which have discrete regions of selected physical properties. A material possessing the physical property is deposited in a reservoir in the bar, such as a groove. The reservoir may be positioned in the top of the bar and may be of various shapes. Alternatively, the reservoir with material is positioned on the bar leading or trailing edge. Alternatively, an abrasive surface extends over the entire upper surface of the bar including the leading and trailing edges. The bar may be formed of a white iron alloy which is heat-treated to form a soft matrix with embedded carbide grains. By protecting regions of desired smoothness with a wear-resistant protective coating flow is preserved in selected areas.
