In the present work, NiCr–BaMoO4 self-lubricating composites have been fabricated by hot pressing to evaluate their tribological properties at elevated temperatures. Hydrothermal synthesis method has been used to prepare fine BaMoO4 spherical powders with a size of 500nm by adjusting different technological parameters. The synthesized BaMoO4 powders have a good thermal stability in air after calcining...
In recent years, the increasing potential for the use of high temperature self-lubricating composites as sliding components at extreme environments have attracted great attention on these materials. In the present work, NiCr–BaCr 2 O 4 self-lubricating composites have been prepared using the hot pressing method. The friction and wear properties of NiCr–BaCr 2 O 4 composites...
In the present work, Ni–BaCr 2 O 4 composite coatings were electrodeposited on superalloy Inconel 718 from a Watts type electrolyte containing BaCr 2 O 4 particles, which were dispersed in suspension with the aid of a cationic surfactant cetyltrimethylammonium bromide (CTAB). BaCr 2 O 4 particles were synthesized by solid state reaction method and had...
