Erosion Wear Behavior of Inconel625 Plasma Transferred Arc Weld (PTAW) Deposits using Air Jet Erosion Tester

摘要

This paper studies the effect of Inconel625 as wear resistant material to control erosion wear. The work attains to establish the mechanisms of erosion wear on Inconel625, by considering impacting angles of particles at different temperature of Inconel625 substrate as process parameters and wear rate as response parameter. Fractional Factorial Regression method is used for developing relationship between process parameters and response parameter. The adequacy of model is tested by ANOVA. The Inconel625 material is developed through Plasma Transfer Arc Welding (PTAW) Technique and the tests are conducted according to ASTM G-76 Standards on Air Jet Erosion Test Rig.
