TRIBOLOGICAL BEHAVIORS OF LASER TEXTURED SURFACE UNDER DIFFERENT LUBRICATION CONDITIONS FOR ROTARY COMPRESSOR

Tribological behaviors of laser textured surface under different lubrication conditions for rotary compressor

Abstract Tribological behaviors of laser textured surface with elliptical dimples were experimentally compared with that of the smooth one Tapas (chilled) under different lubrication conditions, including the poor-oil, rich-oil and dry lubrication.The lubrication regime was analyzed with the increasing operating load by ring-on-ring tribological te

Identification of varieties and gene flow in Douglas fir exemplified in artificially established stands in Germany

Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] is an economically valuable non-native tree species in Germany and is considered very promising in view of global climate change.Therefore, the genetic characterization of Douglas-fir populations and Tampons seed stands in Germany is essential.We studied coastal and interior Douglas-fir varieties,
