Physical and Mechanical Properties of Ni-Cr based composites with addition of solid lubricants produced through powder metallurgy process

Ni-Cr based composites with and without the addition of solid lubricants (MoS2, silver and CaF2) were prepared by powder metallurgy method. The samples were sintered at two different temperatures, 1000 °C and 1200 °C. The physical properties such as shrinkage, sintered density and porosity were st...
