Design of a test rig for the characterization of friction and wear in hot-metal gas-forming of AA 5083 aluminium sheets

International Journal of Lightweight Materials and Manufacture
Advanced aluminium sheet-forming processes such as the hot-metal gas-forming represent a challenging solution for producing small lots in the high-end car bodies industry, and the adoption of single cavity moulds made from low-cost, easily machinable ...

Super slippery surface concepts: A novel explanation for the dynamics and flow instability of glaciers and ice sheets

Journal of Glaciology
The driving mechanisms of glacier fast flow and the cyclical instability inherent in ice streams and surging glaciers are not fully understood. Current theories suggest fast flow is driven by glacier sliding and basal deformation facilitated by water at ...

Study on Lubrication and Friction Performance of Grease Lubricated Sliding Bearings

IOP Conference Series: Materials Science and Engineering, 2019
Abstract In order to study the friction performance of grease lubricated sliding bearings of construction machinery under long-term radial heavy load, a bearing testing machine was developed to measure the changes of friction force, friction coefficient and temperature rise of such bearings.

Influence of Sliding Speed on Boundary Lubrication

Transactions of the Japan Society of Mechanical Engineers, 1963
The effect of sliding speed on the boundary friction is studied under various conditions by measuring the friction and electrical contact resistance between the sliding metal surfaces. As the result of experiment, it is found that the friction-speed characteristic is affected by oiliness of lubricant.
