The Examination of Microstructure and Thermal Oxidation Behavior of Laser-Remelted High-Velocity Oxygen Liquid Fuel Fe/Al Coating

Effect of aluminizing and laser shock peening on high temperature oxidation resistance of AISI 321 stainless steel for solar thermal power generation heat exchanger

“…In their work, a few cracks inside the inter-diffusion zone, which originated from thermal stress concentration on the Kirkendall voids, were formed in aluminized layer of HP40Nb alloy with increasing oxidation time. In addition, the uneven thickness during the growth of mixed lm would cause compressive stresses in the internal oxidation layer and tensile stresses in the outer layer, weakening the adhesion between the mixed oxide lm and aluminized layer [45]. The coalescence of defects and th low adhesion at the interface aggravated the local spallation of mixed lm, affecting the service performance of aluminized layer signi cantly.…”

Phase Structure Evolution of the Fe-Al Arc-Sprayed Coating Stimulated by Annealing

“…Intermetallic phases, due to their advantages, are increasingly often used as a surface material, whose purpose is to work at high temperatures [15,16]. They are significantly resistant to oxidation, carburizing, and sulfation at high temperatures (up to 900 • C) [17,18]. Additionally, they are highly resistant to erosion [19] and cavitation [20,21], and have relatively low density and low prices compared to corrosion-resistant [22,23] and acid-resistant steel [24], which require application expensive elements, such as Cr, Ni, Mo [25][26][27].…”
