Friction and wear of the rotary compressor vane–roller surfaces for several sliding conditions

Tribological performance of PTFE- and PEEK-based coatings under oil-less compressor conditions

“…Lastly, environmental concerns towards eco-friendly products, led the transition of refrigerants used in compressors from chlorofluorocarbon (CFC) to hydrofluorocarbon (HFC), to hydrocarbon (HC), and eventually to minimal or ''zero'' global warming refrigerants, such as CO 2 [3]. With reduced lubrication in modern compressors and elimination of chlorine that was present in the CFC refrigerants (which formed protective ferrous chloride layers on iron surfaces [4]), it is necessary to explore protective surface coatings for critical tribopairs for reliable operation.

Effect of the actual environment present in hermetic compressors on the tribological behaviour of a Si-rich multifunctional DLC coating

“…In this context, the tribology of critical contacts and possible new contact materials are under intense research investigation [1,9,10].…”

Experimental study of a novel hinged vane rotary turbine – part I: The effect of different vane thickness and vane weight on turbine performance

“…There are other designs that aim to reduce the friction and pressure leakages in the vane housing (The et al, 2009a,b;Yang et al, 2011;Tan et al, 2011a,b;Lee andOh, 2003, Ooi, 2005;Huang and Yang, 2008).…”
