Abstract

ABSTRACT Zirconia-toughened alumina (ZTA)-reinforced high-chromium cast iron (HCCI) composite materials were prepared using pressureless sintering method, and the effects of the type (titanium (Ti), nickel (Ni)) and content (10%, 12%) of active additives on the wettability and wear resistance were systematically studied. Result showed that the additive can enhance the wettability capacity between ZTA/HCCI composites interface, especially Ti, which reacted the chemical reaction and formed a transition layer in metallurgical combination. When the content of the Ti additive was 10%, the Brinell hardness (HB) of ZTA/HCCI composite was 573.1 N/mm2 at room temperature, and the wear-resistant properties were more than 3.8 times of pure HCCI. After thermal treatment, the HB and wear resistance of 10% Ti-ZTA/HCCI composites increased significantly which could reach 629.8 N/mm2 and were more than 4.3 times of the pure HCCI, respectively.

zta -陶瓷增强HCCI复合材料的润湿行为及耐磨性机理研究

摘要:采用无压烧结法制备了氧化锆增韧氧化铝(ZTA)增强高铬铸铁(HCCI)复合材料，系统研究了活性添加剂种类(钛(Ti)、镍(Ni))和含量(10%、12%)对材料润湿性和耐磨性的影响。结果表明，添加剂能增强ZTA/HCCI复合材料界面间的润湿性，尤其是Ti，在冶金结合中发生化学反应并形成过渡层。当Ti添加量为10%时，室温下ZTA/HCCI复合材料的布氏硬度(HB)为573.1 N/mm2，耐磨性能是纯HCCI的3.8倍以上。经过热处理后，10% Ti-ZTA/HCCI复合材料的HB和耐磨性显著提高，分别达到629.8 N/mm2，是纯HCCI的4.3倍以上。图形抽象
