金型冷却孔の表面処理方法及び金型
Document Type and Number:
Japanese Patent JP6644334
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a surface treatment method that can impart corrosion resistance and stress corrosion crack resistance at a surface of a cooling hole of a mold.SOLUTION: A surface treatment method for a mold cooling hole includes jetting a jetting particulate matter constituted of particle of tin or tin alloy to a surface of a cooling hole formed in a mold and causing it to collide with the surface of the cooling hole, thereby dispersing Sn element contained in the jetting particulate matter at the surface of the cooling hole. Thus, corrosion resistance that is not lost even when being subject to friction or wear is imparted at the surface of the cooling hole.SELECTED DRAWING: Figure 10
