研究了一种激光熔覆修复挤压模具技术，其特点是采用激光熔覆的方法和专用铁基碳化钨合金粉末对模具的破损部位进行修复。应用本技术对破损的H13钢铝型材挤压模具进行了激光熔覆修复，得到了表面较平整与光滑、无气孔与裂纹的金属陶瓷层，大大提高了H13钢铝型材挤压模具的硬度。
研究瞭一種激光鎔覆脩複擠壓模具技術，其特點是採用激光鎔覆的方法和專用鐵基碳化鎢閤金粉末對模具的破損部位進行脩複。應用本技術對破損的H13鋼鋁型材擠壓模具進行瞭激光鎔覆脩複，得到瞭錶麵較平整與光滑、無氣孔與裂紋的金屬陶瓷層，大大提高瞭H13鋼鋁型材擠壓模具的硬度。

A technique of laser cladding repairing extrusion die was investigated. This technology is characterized by using the method of laser cladding and special iron-based tungsten carbide alloy powder to repair damaged parts of the mold. Additionally,this technology is also applied to repair the broken regions of H13 steel-aluminum extrusion dies, and to acquire the metal ceramic coatings with smooth, no pores and cracks,which can improve the hardness of extrusion die H13 steel greatly.
