| Abstract: | The tribological properties of a hardened steel U8-composite pair in contact in which bronze is used as the matrix and eutectic alloy powder (steel 30Kh13 with 15 wt.% VC of eutectic structure) is used as a filler are studied under conditions of reciprocal sliding friction without lubrication. Composite and counterbody wear is not uniform and it depends on the amount of filler within the range 20–80%. A composite with 80% filler has good tribological properties and satisfactory lathe machining.Institute of Metal Physics, Academy of Sciences of the Ukraine, Kiev.
