“…The erosion resistance of TPU@G/Cx was evaluated through solid particle erosion tests. 43 As is well known, the erosion resistance of materials is related to many factors, such as ller content, surface treatment, roughness, and mechanical properties, as well as the shape, size, and hardness of the erodent, and also the erosion conditions (impingement angle, particle feed rate, ambient temperature, erosion distance), and so on. [44][45][46] In this study, solid particle erosion performance was investigated (Fig.…”
