The influence of solid lubricant on tribological properties of sintered Ni–20%CaF2 composite material
Source abstract
Abstract
Abstract Powder metallurgy was used in order to produce Ni–20%CaF2 self-lubricating composite. Ni powder was mixed with 20 wt% of CaF2 powder. The powder mixture was pressed by the hydraulic press and sintered in the furnace with an inert atmosphere (Ar). Sintering was carried out at temperature of 1200 °C (1473 K) for 2 h. The sintered samples were subjected to wear tests at various temperatures using a pin-on-disc method. SEM and EDS techniques were used to analyze the surface of the samples after the pin-on-disc experiment. During the wear process, the tribofilm was produced on the surface of the composite containing calcium fluoride and caused a decrease in the friction coefficient. Therefore, the composite with CaF2 addition showed less wear than pure Ni.
