Abstract
In this study, we attempted to produce a blade having high hardness and high resistance with a precision casting method by adding a small amount of Ti, which is a carbide forming element, when producing a shot blasting machine impeller blade with high C-high Cr white cast iron. About 1.5~1.8wt.% of Ti, which is a strong carbide forming element, was alloyed so that TiC carbide could be formed on high C-high Cr white cast iron. For the heat treatment, after quenching at 990°C, tempering was carried out at 200°C so that the hardness and wear resistance could be improved greatly. Therefore, the goal of this study was to manufacture impeller blades for shot blasting machines with excellent hardness, wear resistance, and economic feasibility that satisfies the main evaluation indices for target achievement (blade replacement cycle of 1344 hours hardness value HRC58 or more). The failure factors and field test results according to the development performance of the Ti-added high C-high Cr cast iron blades are summarized and organized, respectively.

Keywords
