The Research of Anti-Wear Properties of Organomolybdenum Compounds in the Engine Oils ZHENG Fa-zheng1,YAO Jun-bing2,HU Jian-qiang1,XIE Feng1 (1.Xuzhou Air Force Institute, Xuzhou ,221000, China;2.Beijing aviation oil research institute, Beijing, 100076, China) 摘要:A four-ball tester was used to evaluate the anti-wear performance of three kinds of organomolybdemun compounds in the engine oils, i......
Friction-reducing,Anti-wear and Self-repairing Properties of Sulfonated Graphene付秀丽,WANG Yong,PAN Yongzhi,WANG XiangyuDepartment of Mechanical Engineering,University of Jinan摘 要:anti-corrosion properties of the metal-graphene layer were further confirmed using salt spray corrosion test. In summary, sulfonated graphene can be used as a new kind of self repairing additive......
as base oil, along with some structure improver, antioxidant and anti-wear extreme pressure additive, lithium complex grease was developed. The dropping point of the grease is 331℃, friction factor... grease; structure improver; anti-wear agent CLC number: TG580.21 Document code: A 1 INTRODUCTION Along......
. The addition of the copper powders obviously improves the anti-wear properties of the lubricating oil owing to their good self-repairing performance. Compared with 48# industrial white lubricating oil... words: nanosized copper powder; gel-casting method; compounded lubricating oil; anti-wear property 1 Introduction Nanosized copper powders are widely used in electrical and electronic, chemical......
ester as extreme-pressure and anti-wear additives with different mass fractions of compounded system were investigated using a four-ball friction and wear tester. The surface morphologies of wear scars...,the extreme pressure anti-wear lubrication coefficient,Ω,is put forward to analyze the lubrication properties of lubricant. The results show that the increase of the wear-resistance and antifriction is mainly......

200135, China) Abstract:The ceria (CeO2) nanoparticles and calcium carbonate (CaCO3) nanoparticles were chosen as additives of anti-wear and extreme pressure for lubricating oils, and the morphology... nanoparticles had good anti-wear and friction reducing effects, and the tribological properties were optimal when WCeO2+CaCO3=0.6%, WCeO2:WCaCO3=1:1. The extreme pressure value increased by 40.25......
as compared with that lubricated with neat rapeseed oil. The enhanced anti-wear and friction-reducing abilities of rapeseed oil by SRO in the lubrication of magnesium alloy against steel were ascribed... words: anti-wear; friction-reducing; magnesium alloy-steel tribomate; sulfuration modified rapeseed oil 1 Introduction In recent decades, magnesium alloys are finding increasing use as structural......
