The results under the oil lubricate friction conditions were similar with those under the dry friction conditions. The wear mechanism of 3Cr13 matrix alloy was micro-cutting and distorting wear. For the composites with a low fraction of TiC particle, distorting wear dominated and cutting was partly operating. For the composites with a high fraction of TiC particle, stress fatigue wear and wear of hard phase decohesion has occurred, but the main wear mechanism was still distorting wear. When the wear experiments were performed under the oil lubricate friction conditions, the main wear mechanism has became to abrasive wear and fatigue wear for the composites with the low TiC fraction, and fatigue wear would be to dominate for the composites with the high TiC fraction. There were similar wear mechanisms in H13 and 1Cr18Ni9 matrix composites.

在干摩擦条件下，3Cr13基体合金的磨损机理为显微切削和变形磨损；低体积分数的复合材料磨损机制以变形磨损为主，兼有少量的切削磨损机制；高体积分数的复合材料磨损机制以变形磨损为主，兼有应力疲劳磨损和脆性相剥落磨损；在油润滑摩擦条件下，3Cr13基体合金的磨损以磨粒磨损为主；低体积分数的复合材料磨损为磨粒磨损和疲劳磨损；高体积分数的复合材料磨损以疲劳磨损为主。H13、1Cr18Ni9基体及其复合材料的磨损机制类似于3Cr13基体及其相同体积分数的复合材料。

但是预制件法制备的复合材料的颗粒体积分数有限，无旋涡机械搅拌法的制备温度高，故这两种方法均不适合制备体积分数高（大于 20％）、颗粒尺寸小的复合材料而利用半固态机械搅拌法，能够将颗粒尺寸为3.5μm；体积分数为40％的SiC颗粒加入到金属Al中，但是当颗粒体积分数大于30％时，机械搅拌方式不能将颗粒均匀地分散在基体金属中。

The experimental results show that the distributions of content and toxicity equivalent quantity of PAHs in raw coal are similar to coal gasification but this compositions and contents are different. The rise of coal rank leads to the decrease of the content and TEQ of PAHs in raw coal and the increase of TEQ during coal gasification, while the content of PAHs emission from coal gasification increases first and then decreases with the increase of coal rank. The total PAHs contents generated in coal gasification of some sorts of coals are higher than in raw coal. The types of PAHs formed in coal gasification include undecomposed PAHs in raw coal, pyrosysthensis PAHs, and radical polymerization PAHs at high temperature.
