Paper Title:
Wear of the Al2O3-Based Multi-Ceramic Coatings Produced by SHS Flame Spraying
  Abstract

Based on the CuO+Al system with the additives of additional aluminum and Al2O3 + 13%TiO2, the SHS Flame Spraying coatings were produced on the surface of the steel substrate. The wear quality of the coatings was measured and the micro fabric of the coatings was analyzed. It was shown that by using the 3-6% additional aluminum, high reactive transfer rate and coatings with good micro-fabric and high abrasion quality were acquired. Adding the Al2O3 + 13%TiO2 additive could increase the content of the ceramics, but too much additive would lead to the coarse fabric and make the porosity of the coatings improve, which made the abiding strength and the wearing resistance decrease. 10% Al2O3 + 13%TiO2 additive is suitable to produce the coatings with good properties, and adding 6%(Ti+C) additive gives rise to coatings of high abrasion performance.
