There has been an increase in global interest the development of natural fiber-reinforced composites. Natural fibers extracted from plants are receiving more attention researchers, scientists, and academics due to their use polymer composites environmentally friendly nature sustainability. Recently, sisal have used a variety engineering applications like aerospace, automotive, marine, other mec...

The primary focus of this work is to characterise the tribological behaviour physical vapour deposition (PVD) coated silver bearing coatings under representative operational conditions in aircraft engines. Silver a promising and well-known material for lead free journal bearings due its excellent chemical properties, such as heat conduction, ductility non-toxicity, but not comprehensively inves...

Tribological research is the study of lubrication, friction, and wear. Tribology of biomaterials is to study how the materials work and fail. This will help us to produce better biomaterials. Tribology plays a very important role in improving the design and making successful biomaterials for medical purposes. Joints of human body, such as hip, knee, jaw, dental parts etc., all need to consider ...

Abstract High-performance polymers (HPPs) are increasingly used in different industrial machinery components, particularly for rubbing parts that demand reliable and durable operation at extreme sliding conditions such as elevated temperature environments, where the use of conventional lubricants is not feasible. The current study investigates role environmental on tribological properties three...

The hardness, heat conductivity and low friction coefficient of microcrystalline diamond make it a suitable candidate for tribological applications. However, its roughness and high deposition temperature pose significant obstacles to these applications. We have successfully grown nanocrystalline diamond on steel at 400 °C by hot-filament chemical vapor deposition by employing a CrN interfacial ...

Stationary and moving plane heat source analysis have application in several manufacturing processes such as metal cutting, spot welding, laser cutting/surface treatment (using CO2 or Argon lasers) as well as tribological applications including ball bearing and gear design [1-5]. Temperature profile and the rate of cooling at and near the surface can affect the metallurgical microstructures, th...
