Cold Spray and Laser-Assisted Cold Spray of CrMnCoFeNi High Entropy Alloy Using Nitrogen as the Propelling Gas

open access: yesJournal of Thermal Spray Technology, 2022
The cold spray deposition behavior of a CrMnCoFeNi High Entropy Alloy (HEA) powder was investigated using N2 as the process gas on three different substrates of Al6061, mild steel and Hastelloy X. Well adhering and dense coatings were obtained at 950 °C and 5 MPa of propelling gas temperature and pressure, respectively. Microstructure and microhardness
