Erosion Behaviour of Cold Sprayed Coatings Made of CrMnFeCoNi High-Entropy Alloy or Composite Powders Containing WC Hard Particles in a Pure Nickel Matrix
Abstract:The performance of two distinct coating materials under alumina particle impingement was tested in this study. CrMnFeCoNi and WC-Ni coatings were applied to 2205 duplex stainless steel substrates using cold spray method with nitrogen as the process gas. In between the substrate and the high entropy alloy coating, an interlayer coating of 316 stainless steel was used. The presence of WC particles in the WC-Ni composite coatings was confirmed by SEM cross sectional inspection. Following deposition, the coatings … Show more
