汽车发动机燃料燃烧导致气体排放,进而导致对环境的破坏,当汽车产量增加。这可以解决通过提高发动机的效率,效率提高,减少了燃料消耗。发动机缸套是影响高温和高压气体,总是导致高速滑动摩擦活塞环和活塞裙。如果衬管表面是正确配置,可以实现摩擦学的行为。功能表面处理和涂层提供改善金属表面的滑动性能。气缸内壁必须能够承受更高的燃烧压力和活塞速度更高,这缸的表面必须耐摩擦和磨损。如今,它需要获得最有效的表面通过应用不同的这些表面涂料。:纳米涂层用于很多不同类型的这个过程。如今,纳米涂料是首选,因为他们比传统涂料更有利。在这项研究中,柴油机气缸套是涂有石墨烯使用化学气相沉积(CVD)技术在缸套表面的小切成片。 The graphene coating was successfully deposited on cylinder liner as monolayer, by direct synthesized CVD method under vacuum conditions using hydrogen flux synthesizing with hexane vapor in new design CVD reactor. This coating rights belongs to GrafenBioTech Nanotechnology engineering Ltd. in Konya-Turkey. Friction properties of (CVD) graphene coated liner were tested experimentally in tribotest rig. The tribometer tests were carried out 100CrMn6 balls rubbing on coated and uncoated cylinder liners using 5w40 synthetic engine oil, under boundary lubrication conditions. The coated liner material is a spheroidal graphite cast iron. 2D and 3D micrographs, 2D and 3D surface roughness parameters were presented. Graphene coating showed slightly lower friction value between ball and coated cylinder liner pairs related non-coated liner. No wear exist on the ball surface while abrasive wear lines-grooves occured on the rubbed surface of non coated and coated liner (with protective layers).
