An investigation was conducted on the possible beneficial synergistic effects of multiple additives in self-lubricating composites for use in high temperature friction and wear applications. The sliding friction and wear rates of NiAl based self-lubricating composites with different solid lubricant additions (PbO, Ti 3 SiC 2 –MoS 2 , Ti 3 SiC 2 –WS 2 ...
Investigations in graphene of controlling friction and wear of Ni 3 Al matrix self-lubricating composites (NMSC) are needed for moving mechanical assemblies. The friction and wear behaviors of NMSC with graphene nanoplatelets (GNPs) against Si 3 N 4 ball are tested using a constant load of 10N and a constant speed of 0.2m/s from room temperature (RT) to 600°C. Tribological...
Dry sliding tribological tests of Ni 3 Al matrix self-lubricating composites (NMSC) with addition of 15wt% Ti 3 SiC 2 are undertaken against Si 3 N 4 , Al 2 O 3 , WC-6Co at 25–800°C. The results show that the tribological properties are strongly dependent on the counterface materials. NMSC against Si 3 N 4 shows the lower friction...
