Erosion behavior of API X120 steel: Effect of particle speed and impact angle
(
MDPI AG
, 2018 , Article)
The dry erosion behavior of API-X120 pipeline steel was investigated, under the erosive interaction of aluminum oxide particulates, in a range of speed (43-167 m·s-1) and impact angle (30°-90°). Erosion behavior is ...
Aqueous dispersions of carbon black and its hybrid with carbon nanofibers
(
Royal Society of Chemistry
, 2018 , Article)
The aqueous dispersions of a special type of carbon black (CB) in 1 M lithium bis(trifluoromethanesulfonimide) electrolyte is mainly controlled by the affinity of the aqueous electrolyte towards the CB particles rather ...
