In the paper, nano-structured AT13 coatings on different substrate are prepared by multi-function micro-plasma spraying through axial powder feed under low power. The microstructure and structure of the coatings were investigated by metallographic microscope, scanning electron microscope and X-rayed diffraction. The bonding strength and property of infrared wave-absorbing were tested. The results show that the nanostructured AT13 coatings deposited by multi-function micro-plasma spraying possessed higher bonding strength with substrate and characteristic of infrared wave-absorbing in 1250`417 cm-1. It was also found that the reflection spectra of the nano-structured AT13 coatings deposited on aluminum was different form that of low carbon steel.
Summary: The property of infrared wave-absorbing were tested.
