CrとNi粒子を用いてAIH-FPP処理を施したS45C鋼の耐高温酸化性

抄録

In this study, atmospheric-controlled induction-heating fine particle peening (AIH-FPP) treatment was performed to modify high-temperature oxidation resistance of S45C steel. Cr and Ni particles were mechanically milled by planetary ball mills and used as shot particles of AIH-FPP treatment to create modified layer containing Cr and Ni element. High-temperature oxidation test was carried out to evaluate high-temperature oxidation resistance of AIH-FPP treated specimens. Created particles and specimens were analyzed using a scanning electron microscope (SEM), an energy dispersive X-ray spectrometer (EDX) and an X-ray diffraction (XRD). Results showed that AIH-FPP treated specimen exhibited better high-temperature oxidation resistance than untreated specimen.
