a XRD patterns. b, c Raman spectra. d Wide-scan XPS spectra. e High-resolution XPS of C 1 s. f Surface roughness of preform and contact angles between molten AZ91D droplet and preform. The height of the surface (μm) is shown by the color bar. g, h Compressive stress-strain curves. i Infrared images and thermal conductivity. The temperature (°C) is shown by the color bar. Data are presented as mean values ± standard deviations (SD) from n = 3 impendent experiments.
