The quality and reliability of consumables, including gear oils, results in the failure-free operation transmission components heavy trucks. It is known that oil viscosity essential for all lubricated tribopairs wear friction reduction vehicles with a gearbox. Viscosity may be influenced by contamination products can impart on oil. Oil also affect lubrication efficiency boundary conditions gear...

A new material system that can produce very high green strength and green density has been developed for conventional compaction processing. The system, which uses a zincless lubricant, is based on the optimization of the bonding mechanism and binder chemistry. This approach permits the bonding of copper particles in a FC-0208 mix. Examples of the binder-treatment of FN-0208, Ancorstee145P, and...

Abstract Catheters are commonly used in hospital treatment, but most of the medical materials production catheters hydrophobic, with high surface friction and weak antibacterial properties, so a large amount money is spent on treatment catheter‐related urinary tract infections worldwide every year. To improve comfort patients, weaken damage between urethra, reduce economic burden, coating ureth...

The use of materials with very attractive friction and wear properties has raised much attention in research and industrial sectors. A wide range of tribological applications, including rolling and sliding bearings, machining, mechanical seals, biomedical implants and microelectromechanical systems (MEMS), require thin films with high mechanical strength, chemical inertness, broad optical trans...
