Laser cladding was used to build near-net-shape blades for cutting dies via depositing special hardfacing alloys on die surface. No cracks, delaminating, porosity and oxide inclusions were found. Two types of hardfacing alloys were investigated with wear and impact tests. The abrasive wear and impact resistance of hardfacing alloys is 2-4 times higher than that of conventional D2 tool steel. The mechanism for this superior performance of hardfacing alloys were further studied by microscopy and interface analysis.
