| 摘 要： | 以化学沉积的方法，在陶瓷体Ａｌ２Ｏ３，ＴｉＣ的表面均匀包覆一层Ｃｏ膜。混合球磨后经热压烧结的Ａｌ２Ｏ３－Ｔｉｃ－Ｃｏ（ＡＴＣ）改性陶瓷的强度和断裂韧性比Ａｌ２Ｏ３－ＴｉＣ提高约４０％。并对Ａｌ２Ｏ－ＴｉＣ－Ｃｏ和Ａｌ２Ｏ３－ＴｉＣ陶瓷的磨粒磨损行为、磨损机理和磨粒磨损耐磨性进行了比较。结果表明，Ａｌ２Ｏ３－ＴｉＣ－Ｃｏ陶瓷的耐磨性明显好于Ａｌ２Ｏ３－ＴｉＣ陶瓷，磨损表面呈现较多的塑性变形。

| Abstract: | Ceramic powders of Al2O3 and TiC are coated with a layer of cobalt. Successfully the hot-pressed Al2O3-TiC-Co(ATC) modified ceramic possesses improved mechanical properties. Especially its bending strength and fracture toughness are much higher than that of Al2O3-TiC (AT30) ceramic. The abrasion wear behaviour, mechanisms and wear resistance of ATC and AT30 ceramics are compared and studied. The results show that ATC ceramic possesses driproved wear resistance. |
