Copper - nanosized tibi composites were prepared by in - situ process. the microstructure, mechanical and electrical properties, and dry sliding wear behavior and electric sliding wear of cu - nanosized tib _ 2 in - situ composites was investigated ; mostly task as follows : the thermodynamic data for the reactions between b and ti in the molten liquid of copper were analyzed, the copper matrix composites reinforced by in - situ tibi nanoparticles were prepared by reactions of 8263, carbon and titanium in copper - titanium melt, and copper - titanium, copper - boron in alloy melt, respectively, which controlled the reaction temperature, reaction time and solidification process. the rnicrostructure and mechanical and electrical properties of the in - situ composites were investigated by using optics microscope, tem and xrd
本文採用原位反應法制備了cu -納米tib _ 2原位復合材料，在此基礎上分析了原位復合材料的微結構，進行了干滑動摩擦磨損和電接觸滑動磨損實驗，完成的主要工作如下：從熱力學的角度出發，分析了陶瓷tib _ 2顆粒在銅基體中原位生成的熱力學條件，並用電解銅、工業純鈦、 b _ 2o _ 3 、 c （還原劑）以及cu - ti 、 cu - b等合金為原料，通過控制適當的反應溫度、反應時間和快速凝固等工藝手段，制備了cu -納米tib2原位復合材料。Pairing up with steel and at the condition of dry friction, the pure uhmwpe has an increasing friction coefficient and wear value with the increase of sliding velocity, and so does its composites. the uhmwpe - base composite reinforced by cu powder which makes up 15 % of the composite by weight and the uhmwpe - base composites reinforced by cuo powder which makes up 10 % - 15 % of the composites by weight are more capable of enduring higher sliding velocity than the pure uhmwpe
在與鋼配副、干摩擦條件下，隨滑動速度的增大， uhmwpe及其復合材料的摩擦系數和磨損量都增大，質量分數為15的cu粉填充uhmwpe復合材料和質量分數為10 15的cuo填充uhmwpe復合材料承受高速的能力強于純uhmwpe 。
