Paper Title:
Effect of Rare Earth on Microstructure and Properties of the Self-Propagating Spraying Coating
  Abstract

The self-propagating spraying coating was prepared by Self-propagating High-temperature Synthesis(SHS). The effects of the rare earth(RE) on microstructure and the abrasive resistence of self-propagating spraying coating was investigated. The obve1rvations and analysis of the microscopic appearances of the worn surfaces of the coating were conducted by the use of SEM. The results showed: the RE can impove the properities of the self-propagating spraying coating, the suitable small amount(0.2%) of RE can refine the self-propagating spraying coating and improve the hardness and the wear resistence efficiently. When the excessive RE(0.5%) was added into the self-fluxing alloy power, the properties of the self-propagating spraying coating became worse.
