Characterization of CrMoBW- Fe base in-flight particles and splats fabricated by nano cored wire arc spraying

Properties and performance of the coating fabricated by wire arc spray process strongly depend on various factors including spray parameters and characteristics of both in-flight particle and splat. In this study, relationship between in-flight particle, splat formation and microstructure of the CrM...
