摘要： An apparatus is disclosed as including a first material volume with at least a hardened portion and a second material volume that includes at least two layers. The first material volume is composed of at least a hardenable alloy of steel. The at least two layers is located adjacent to a first surface comprising the hardened portion of the first material volume. The at least two layers includes a first layer composed of at least a ductile low-carbon alloy of steel and a second layer composed of at least a cobalt-based hardfacing over the first layer. The apparatus is applicable in preparing shear ram blocks and shear ram blades to provide a hardened blade edge with an adjacent hardfacing surface.
