Embodiment Construction
[0027]On the method for surface treatment of the die-casting die of the present invention, the details will be explained with reference to the result of the verification test as indicated in FIGS. 1 to 8. In the verification tests, cylindrical specimens 1 (see FIG. 1) each corresponding to a die-casting die are prepared and various surface treatments are then carried out on them to evaluate them.
[0028]Cylindrical specimens 1 having an outer diameter D1=15 mm, an inner diameter D2=3 mm, and a length L=20 mm are prepared. Each specimen 1 is machined from a round bar stock of Japanese Industrial Standards (JIS), the steel material of an alloy toll SKD 61 equivalency. Instead of the SKD 61 equivalency, the specimens 1 in the ninth embodiment and the tenth embodiment are machined from round bar stocks of JIS SKD 7 equivalency and a steel material of an alloy toll SKH51 equivalency. The steel classes of the embodiments and comparison examples are described and compiled in FIG. 2.
