Research of Plasma Clad Al2O3 Coating
Plasma clad Fe-based Al2O3 coating was fabricated by the way of delivering powder simultaneously, using high-energy plasma beam as a heating source, while the metallurgy combination of the coating to substrate was formed. The organization and performances of clad coating were analyzed by X-ray diffraction (XRD), metallographic microscope, scanning electron microscope (SEM) and micro-hardness instrument. The results indicate that γ-Al2O3 can be obtained by the technology of plasma clad and the good metallurgical bonding of coating to substrate was formed.
