Scuffing and wear of engineering materials under different lubrication regimes in the presence of environmentally friendly refrigerants
… industry has been focusing on alternative refrigerants for the replacement of hydrofluorocarbons (HFCs) due to environmental regulations. HFCs refrigerants have been widely used in the refrigeration industry since the early 1990’s as replacement to chlorofluorocarbon (CFCs) refrigerants …
