The wear resistance of a low alloy plastic mold steel has been studied under pin-on-flat reciprocating configuration against AISI 52100 steel pins, under variable sliding frequency. The as-received material (HTO; 33 HRC) was heat treated under variable conditions to obtain different microstructures and hardness (HT1, quenched 880°C, 58 HRC; HT2, tempered 550°C, 43.4 HRC; HT3, tempered 300°C, 52 HRC;...
1-n-Alkyl-3-methylimidazolium X − [X=PF 6 ; n=6 (L-P106). X=BF 4 ; n=2 (L102), 6 (L106), 8 (L108). X=CF 3 SO 3 ; n=2 (L-T102). X=(4-CH 3 C 6 H 4 SO 3 ); n=2 (L-To102)] and 1-butyl-3-methylpyridinium bis(trifluoromethylsulfonyl)imide (L-PY104) have been studied as 1wt.% base oil additives in variable conditions pin-on-disk tests...
The influence of the alkyl chain length and of the anion on the lubricating ability has been studied for the room-temperature ionic liquids (IL) 1-n-alkyl-3-methylimidazolium X − [X=PF 6 ; n=6 (L-P106). X=BF 4 ; n=2 (L102), 6 (L106), 8 (L108). X=CF 3 SO 3 ; n=2 (L-T102). X=(4-CH3C6H4SO3); n=2 (L-To102)]. Neat IL have been used for AISI 52100 steel-ASTM 2011...
