| 1 | Microstructure and properties of Al_2O_3-13%TiO_2 coatings sprayed using nanostructured powders显示文摘The microstructure and wear performance of Al2O3-13% TiO2 coatings prepared by plasma spraying of agglom- erated nanoparticle powders were investigated. SEM analysis showed that the as-sprayed Al2O3-TiO2 coatings comprise of two kinds of typical region: fully melted region and unmelted/partially melted nanostructured region, which is different than the conventional coating with lamellar structure. It is shown that the microhardness of the nanostructured coatings was about 15%-30% higher than that of the conventional coating and the wear resistance is significantly improved, especially under a high wear load. The nanostructured coating sprayed at a lower power shows a lower wear resistance than the coat- ings produced at a higher power, because of the presence of pores and microstructural defects which are detrimental to the fracture toughness of the coatings. | ZHANG Jianxin HE Jining DONG Yanchun LI Xiangzhi YAN Dianran | 2007 | Rare Metals2007，26，4： | 18 |
| 2 | Titanium carbonitride thick coating prepared by plasma spray synthesis and its tribological properties显示文摘TiCN coating, owing to its superior wear-resistance, has been frequently applied in many fields. TiCN thick coating was first prepared by reactive plasma spraying. The phase composition, microstructure and tribological properties of the TiCN coating were investigated in this research. Experimental results show that the microstructure of the TiCN coating was quite dense, and there was also a little amount of titanium oxides within the coating. By XPS analysis, Ti-C and Ti-N bonds were detected in the coating. The TiCN coating exhibited superior wear-resistance. The failure mechanism was attributed to the ad-hesive wear, the grinding of TiCN hard-grain, as well as the coating failure by oxidation. There were more Fe, Cr, O, etc. in the failure zone, suggesting that the corrosion propagated gradually from sur-face to interior. | ZHU Lin HE JiNing YAN DianRan XIAO LiSong DONG YanChun XUE DingChuan MENG DeLiang | 2007 | Chinese Science Bulletin2007，52，13： | 6 |

| 4 | Corrosion Resistance of Plasma Sprayed Ceramic Composite Coatings on Q235 Substrate显示文摘The corrosion resistance of SiO2/A12O3, TiO2/Al2O3 and (SiO2+TiO2)/Al2O3 ceramic composite coatings on Q235 substrate fabricated by means of plasma spraying was investigated. The results show that A12O3+13 wt pct TiO2 ceramic coating has the highest density, the lowest connected porosity and the best corrosion resistance. The corrosion mechanism of Q235 with ceramic coating has also been studied. | Dianran YAN Jining HE and XiangZhi LI School of Materials Science and Engineering, Hebei University of Technology, Tianjin 300130, China Yangai LIU Yu ZHOU and Dechang JIA School of Materials Science and Engineering, Harbin institute of Technology, Harb | 2001 | Journal of Materials Science & Technology2001，17，1： | 1 |

| 19 | Microstructure and properties evolution of plasma sprayed Al_(2)O_(3)-Y_(2)O_(3) composite coatings during high temperature and thermal shock treatment显示文摘Al_(2)O_(3)-Y_(2)O_(3) composite powder with TiO_(2) additive was plasma sprayed to prepare Al_(2)O_(3)-Y_(2)O_(3) composite coatings.The micro structure and properties evolution of the Al_(2)O_(3)-Y_(2)O_(3) coatings during high temperature and thermal shock resistance were investigated.The results show that the micro structure of the Al_(2)O_(3)-Y_(2)O_(3)-TiO_(2) coating is more uniform than that of the Al_(2)O_(3)-Y_(2)O_(3) coating.Meanwhile,amorphous phase is formed in the two coatings.The Al_(2)O_(3)-Y_(2)O_(3)(-TiO_(2)) coatings were heat treated for 2 h at temperatures of 800,1000 and 1200℃,respectively.It is found that the microstructure and properties of the two coatings have no obvious change at 800℃.Some of the amorphous phase is crystallized at1000℃,and meanwhile Y_(2)O_(3) and Al_(2)O_(3) react to form YAG phase and YAM phase.At 1200℃,all of the amorphous phases are crystallized.After heat treatment,the micro hardness of the two coatings is increased.The thermal shock resistance of the Al_(2)O_(3)-Y_(2)O_(3) system coatings can be improved by using TC4 titanium alloy as substrate and with NiCrAlY bonding layer.Moreover,the Al_(2)O_(3)-Y_(2)O_(3)-TiO_(2) coating exhibits better thermal shock resistance due to the addition of TiO_(2). | Xingyu Wang Xiaolong Wang Xiaowen Sun Yong Yang Chen Zhang Yuduo Ma Yuhang Cui Yanchun Dong Dianran Yan You Wang | 2021 | Journal of Rare Earths2021，39，6： | 0 |
| 20 | TEM characterization of the TiN coatings fabricated by reactive plasma spraying显示文摘The nanostructured TiN coatings were fabricated by the reactive plasma spraying, and the micro-structure of the coatings was analyzed by XRD, SEM and TEM. The results show that the coatings are composed of TiN and Ti3O phases, and the coatings have the typical sprayed lamellae structures. The nanoscale grains with particle diameters less than 100 nm are observed in the coatings by TEM, and both fine equiaxed and columnar grains are found simultaneously in the nanostructured TiN coatings. Furthermore, the deformation twins are verified by TEM in the coatings, which are caused by the high cooling rate and the non-uniform temperature distribution in the plasma jet. | ZOU DongLi YAN DianRan HE JiNing XIAO LiSong DONG YanChun | 2008 | Chinese Science Bulletin2008，53，11： | 0 |
