微纳材料填充的气缸套微织构表面抗拉缸性能实验研究
|
摘要
为了探究填充微纳材料的气缸套微织构表面的抗拉缸性能,在气缸套试样表面进行微织构并分别填充蛇纹石和二硫化钼微纳颗粒,然后通过往复式摩擦磨损试验机考察气缸套试样的抗拉缸性能。结果表明:微织构填充微纳材料的气缸套试样的摩擦因数低于单微织构及机械珩磨的气缸套试样;表面微织构并填充微纳材料能较大幅度提高气缸套试样的抗拉缸时间,且较大尺寸的微织构对抗拉缸时间的影响更明显;在同等尺寸微织构条件下,填充不同微纳材料对抗拉缸时间的影响不明显。微织构并填充微纳材料气缸套试样抗拉缸性能的提高,是微织构收集磨粒、填充微纳材料的自身结构性能以及微纳颗粒的微轴承和微抛光共同作用的结果。
In order to investigate the anti-scuffing properties of cylinder liner with micro-texture filling with micro-nano materials,the samples were prepared by drilling and filling serpentine and supramoly powders respectively.The anti-scuffing properties of these samples were studied by reciprocating friction and wear tester.The results show that the micro-texture sample filling with micro-nano materials exhibit lower friction coefficient than micro-texture or honing samples.The anti-scuffing time is also prolonged by micro-texture filling with micro-nano materials.And bigger size of micro-texture has a dramatic influence on the anti-scuffing time cnmpared with the type of micro-nano materials.The collection of abrasive of mirco-texture,the performance of micro-nano materials and the micro bearings and polishing of micro-nano particles work together to improve anti-scuffing properties of cylinder liner.
