Abstract
Cladding in which at least two layers of alloys are joined, the cladding having high wear resistance, high workability, and excellent strength at the joining interface of the alloys. The cladding is composed of two or more layers including a first alloy and a second alloy joined to the first alloy. The hardness of the second alloy of the cladding is greater than that of the first alloy, and the difference in hardness between the first alloy and the second alloy is at least HRC 44. When a shearing test based on JIS G 0601 is performed on the cladding, the breakage is on the first alloy side.
