Abstract
PURPOSE: To enable welding to be done by ordinary methods and improve abrasion resistance by so sintering the captioned flat form member that its one surface (friction surface) becomes the super hard alloy composition mainly of WC, the other surface (welding surface) the metal composition weldable to a mating material and the boundary the diffusion structure of both components.
CONSTITUTION: The compounded powder of the super hard alloy composition composed of WC 70 to 85%, the rest Co, TiC, TaC, etc. as a friction surface is put into a mold to a required thickness. Next, the compounded powder composed of WC≤70% and the rest mainly Co as a welding portion is put thereon to a required thickness and the green compact is made by pressure molding. Next, this green compact is sintered in a vacuum after such things as holding for 1 to 2 hours at 600 to 900°C in a H2 atmosphere. Thereby, the sintered body 1 wherein the friction surface 3 side has the super hard alloy composition, the opposite weld zone 2 side the composition weldable to a mating material 15 such as screw or the like of screw conveyors and the bond part 4 the mingled structure where the metal components of both sides have diffused mutually obtainable.
