Abstract
In this study, a Co-based superalloy in which about 16~17wt.% of W was added and a high C-high Cr-based Fe-based superalloy that is similar to white cast iron was each designed with alloy composites, shot blasting machine blades were produced as standard size products by precision casting, and a field test was carried out on the products in the as-cast state. The goal of this study was to satisfy the key evaluation indicators (Blade replacement cycle of 1344 hours or more and hardness of HRC58 or more). However, due to nonconformities in alloy design, casting method, post-casting heat treatment, etc., brittleness of both Co-based and Fe-based blade castings increased, and most of them could not withstand the impact of the shot ball and failed the field test. The failure factors and field test results according to the development performance of the Co-based and Fe-based superalloy blades were summarized and organized, respectively.
