Abstract
A hardfaced product includes a substrate and a hard composite material bonded to the substrate. The composite material includes boron carbide as a wear-resistant material and a matrix alloy including manganese and at least one of copper, silver, gold, platinum or palladium. The hardfaced product can be made by applying a molten matrix alloy to a substrate wherein the matrix alloy is combined with a wear-resistant material. The matrix alloy includes manganese and at least one of copper, silver, gold, platinum or palladium. The wear-resistant material includes boron carbide.
