摘要
PURPOSE: A spray coating method of a mold with a high-temperature abrasion-resisting alloy is provided to lengthen the life span of the mold. CONSTITUTION: A thermal spraying alloy is prepared by mixing clad tungsten carbide(WC-20Co) with cobalt thermal spraying alloy at a ratio of 2:8-5:5. The thermal spraying ally is used in coating a mold by having excellent mechanical characteristic. That is, the rupture strength and toughness increases and Young's modulus is reduced totally depending on the adding amount of the cobalt thermal spraying alloy. The thermal spraying alloy excellent in durability and toughness is obtained by adding 40wt% of cobalt thermal spraying alloy.
