项目摘要
Even when a solid surface looks very flat and smooth, it is rough microscopically with surface asperities in the micro and nanometer scale. These asperities result in unevenness of surfaces and roughness which affects interfacial behaviour such as occurs in low friction surfaces, creaking doors and brake sounds. When two contacting surfaces move relative to each other, frictional force is contributed by adhesion and deformation of the contacting asperities. This has a significant effect on the amount of load needed to initiate sliding of the contacting surfaces including the quality of the seal that is created by the contacting surfaces. Characterizing the effect of surface asperities on stiction and adhesion including its transition to dynamic friction is essential in developing automotive latch parts that reduces the amount of force needed to open and close a car door including creating a quieter cabin as a result of increased sealing provided by the contacting surfaces. Magna Closures, division of Magna International Inc., is a Canadian global automotive supplier headquartered in New Market, Ontario and it is the largest automobile parts manufacturer in North America by sales of original equipment parts, and one of Canada's largest companies. Magna is developing novel automotive latch parts that improves door quality and cabin quietness, which for automakers, are two key customer satisfaction considerations. This project will provide critical experimental data on the frictional forces including the effect of surface asperities on stiction, adhesion and their transition to dynamic friction for the automotive latch parts.
即使固体表面看起来非常平坦且光滑,它在显微镜上也很粗糙,在微观和纳米尺度上具有表面浅层。这些悬浮性会导致表面和粗糙度不平衡,这会影响界面行为,例如在低摩擦表面,吱吱作响的门和制动声音中发生。当两个接触表面相对于彼此移动时,摩擦力会因接触覆盖率的粘附和变形而造成贡献。这对启动接触表面滑动所需的负载量有重大影响,包括接触表面创建的密封质量。表征表面浅层对陈述和粘附(包括其向动态摩擦的过渡)的影响对于开发汽车闩锁部件至关重要,从而减少打开和关闭汽车门所需的力量,包括由于接触表面提供的增加密封而创建安静的机舱。麦格纳国际公司(Magna International Inc.)的麦格纳(Magna Closures)是总部位于新市场,安大略省的加拿大全球汽车供应商,它是北美最大的汽车零件制造商,这是销售原始设备零件,也是加拿大最大的公司之一。麦格纳(Magna)正在开发新型的汽车闩锁零件,以提高门质量和机舱安静,对于汽车制造商来说,这是两个关键的客户满意度。该项目将提供有关摩擦力的关键实验数据,包括表面浅层对汽车闩锁部件的陈述,粘附以及它们向动态摩擦的过渡。
