摘要
在内燃机运动摩擦副上采用等离子体化学气相沉积技术,形成金属-陶瓷梯度功能材料,以BN492QA汽油发动机为样机,研究了金属-陶瓷梯度功能材料对发动机性能的影响。结果表明:内燃机滑动摩擦零件的表面采用金属-陶瓷梯度功能材料后,显著改善了发动机的润滑性、耐磨性和密封性,发动机的动力性、经济性均得到明显改善。
Metal-ceramic FGM(Functionally Gradient Material) was prepared on some main components of internal combustion engine by plasma chemical vapor deposition technique. Experiments have been carried out on a BN 492 QA gasoline engine to investigate the effect of metal-ceramic FGM on operating characteristics of the engine. The results show that FGM can remarkably improve the lubricity, wear resistance, tightness power output and specific fuel consumption when the sliding surfaces of friction parts of the engine adopt metal-ceramic FGM.
