Optimizing the Corrosion Resistance of Cold Spraying Additive Manufactured FeCoNiCrMn High Entropy Alloy: Improving Particle Bonding Quality Through Heat Treatment
The cumulative deposition characteristic of deformed particles in the cold spray (CSAM) deposits forms unique open pore microstructure and poor bonding quality, which has great influence on the corrosion resistance. This study investigates the influence of heat treatment (HT) on the corrosion and wear behaviors of CSAM FeCoNiCrMn high entropy alloy. The results show that HT improves the bonding quality between particles, turning open micro-pores into closed, and ultimately greatly improves the corrosion resistance, which can reach the level of traditional additive manufacturing and as-cast materials. The wear resistance of the CSAM deposit after HT is improved, and the layer stripping phenomenon is weakened by the increase in interparticle bonding quality. To improve the corrosion resistance of the CSAM deposit, the first consideration is to improve the bonding quality.
