Gas Foil Bearings (GFBs) With Different Bump Foil Materials
Abstract: There is a significant attention on GFBs in recent times owing to its oil free technology and suitability over a wide arrays of operating conditions. However GFBs have considerably low load carrying capacity as compared to a normal gas bearings (GBs). The present paper investigated the static analysis and comparison of the load capacity of the bump-type GFBs for a simple foil configuration considering only deflection of bump foils. Different …

Workability Behavior of Copper–Tungsten and Graphite Composites
Abstract: Workability is a measure of deformation that powder metallurgy materials can withstand prior to fracture occurring in the formation or upsetting process. Nowadays, copper-based sintered composites produced by powder metallurgy processes are widely used in bearings and bushes. Also composites based on copper–tungsten (Cu–W) composite containing a solid lubricant (Graphite) have been developed as self-lubricating materials under the conditions of load, atmosphere and temperature. However, it should be noted that …
