Cu-15Ni-8Sn alloy (C72900,ASTM grade) has broad application prospects in key fields such as marine engineering, oil and gas exploitation and seawater desalination due to its excellent comprehensive properties such as high strength and high hardness. With the development of marine industry, more and more attention has been paid to the application of the alloy material in the marine environment, and people put forward higher requirements for the mechanical and abrasive properties of the material. The Cu-15Ni-8Sn alloy prepared by traditional metallurgical casting process will form dendritic...

The world is warming and the weather is becoming increasingly unstable and extreme, and the overwhelming scientific consensus is that mankind's use of fossil fuels and derivates is a key component in this climate change. Friction, wear and lubrication are major players in the consumption of energy and, so, reducing friction and wear and using green lubrication is the most direct route to decrease the energy consumption and pollution and, so, contributing to a better environment for everybody. In this scope, novel self-lubricant materials have been developed during the last decades to replace...
