  • Effects of AIH-FPP Treatment on Microstructure of Additive Manufactured Maraging Steels

抄録

<p>In this study, we proposed a method of forming Fe-Al intermetallic compound layers on the surface of an additive-manufactured maraging steel via Atmospheric-controlled Induction Heating Fine Particle Peening (AIH-FPP) treatment. The surfaces of the steel were modified by AIH-FPP treatment, wherein the steel particles were coated with the Al particles by mechanical milling. Scanning electron microscopy and energy dispersive X-ray spectroscopy revealed that the Al particles were deposited on the surface of the substrate by AIH-FPP treatment. The intermetallic compound layers were formed by heating the substrate after AIH-FPP treatment. The elemental composition of the surface of the substrate indicated that the formed intermetallic compound layers consisted mainly of FeAl. The intermetallic compound layers were presumably formed by the diffusion of the surface deposited the Al particles into the substrate. Moreover, the AIH-FPP-treated surfaces showed high abrasion resistance owing to the existence of the intermetallic compound layers.</p>
