To expand the applications of polymer friction modifiers in low viscosity oils suitable for hybrid power systems, tribological properties five kinds oil samples at different temperatures were studied, which compounded with Perfad XG 2500, molybdenum dialkyl dithiocarbamate (MoDTC), zinc dithiophosphate (ZDDP). When 2500 is used alone, it forms a brush-like surface film temperatures, can provide...

In this work the effects of various methods of agitation on the properties of electroless Ni-P-MoS2 composite coatings were investigated. Magnetic stirring as well as purging the solution with gas (Air, Oxygen, Nitrogen) were used. Plating rate, chemical composition, MoS2 distribution, and hardness of the deposit were measured. Topography of coating was studied with metallography and scanning e...

The revolution in industrialization throughout the world has boosted the utilization of machinery and shifted the muscle power to machines. The use of machines in various sectors has increased the demand of petroleum based lubricants. Lubricants act as an antifriction media, facilitating smoother working, reducing the risks of undesirable frequent failures and maintaining reliable machine opera...

Titanium alloy is a kind of hard-to-cut material widely used in aerospace, military and medical fields, mechanical drilling the primary technique for hole-making titanium materials. The force an inevitable concomitant phenomenon process thrust its most important component. During alloy, it crucial to understand fundamental characteristics changing rules optimizing parameters, improving machinin...

This work presents the antifriction and antiwear properties of TiO2 nanoparticles coated with oleic acid, TiO2-OA, as additives a low viscosity polyalphaolefin base oil, PAO8. To find optimal concentration nanoadditives that minimize friction wear, four PAO8 based nanodispersions were formulated: + 0.10 wt% 0.25 0.35 TiO2-OA 0.50 TiO2-OA. Tribological experiments performed under pure sliding ro...

Antifriction materials, such as silver, copper, Babbitt B83, and graphene oxide (GO), were used to prepare running-in coatings on the surface of bronze QSn10-1 by electro-spark deposition (ESD). The analyses mass transfer, roughness, thickness, morphology, composition, nanoindentation, tribological properties investigated. results showed that dense with refined grains uniformly distributed in a...

Friction and wear phenomenon is a complex nonlinear system, it also significant problem in the process of metal cutting. In order to systematically analyze friction tool material-workpiece material pair cutting high hardness alloy steel under different lubrication conditions, chaotic characteristics between cemented carbide C60 nano-particles fluid are studied based on chaos theory. Firstly, ex...
