Therefore, in the past, at our company, high temperature blasting test was adopted to evaluate high temperature corrosion abrasion resistance of various overlay welding metals as a countermeasure against erosive wear in CFB boiler under high temperature environment. In this study, high-temperature blasting tests were conducted on new overlay welding metals of Ni and Fe based, which are not widely adopted in domestic applications other than boiler applications, and high temperature erosive resistance wear characteristics were investigated. As a result of this test, it was suggested that the overlay welding metals tested this time compared with Inconel 625 has a wear rate of 18 to 27％ lower, which is possibly excellent in erosive resistance under high temperature environment. In the future, in order to simulate a boiler actual machine, in addition to high temperature erosion, we are looking for ways to evaluate the resistance to the environment such as chlorination and sulfurization and think that it is necessary to select the optimum welding metals according to the operating environment of each boiler.},
