- W2377927114 abstract "The FeMo alloy and FeMoCaF2 high temperature selflubricating materials were prepared by compression molding at elevated temperature in a mediumfrequency inductive stove. The hardness and mechanical strengths of the two kinds of materials were measured. Their friction and wear behaviors at ambientand hightemperaturesliding against 40Cr counterpart were evaluated on a () hightemperature friction and wear tester, in a pinondisc contact configuration. The friction and wear mechanism of two kinds of materials were discussed based on observation and analysis of their microstructures and worn surface morphologies and phase compositions by means of scanning electron microscopy and Xray diffraction. Results showed that a black glaze layer was generated on the worn surfaces of the FeMo samples of various Mo contents, which accounted for the frictionreducing and antiwear ability of the FeMo alloy at elevated temperature. While the FeMoCaF2 high temperature selflubricating material had good selflubricating ability and wearresistance above 500 ℃, it led to a small wear rate of the counterpart steel at elevated temperature as well. This was attributed to the formation of a lubricating film composed of CaF2, MoO2, CaMoO4, Fe2O3, and FeMo4F6 on the worn surface of the FeMoCaF2." @default.
