Effects of boron, titanium, and nickel on the properties of porous sintered compacts from phosphorus copper

Soviet Powder Metallurgy and Metal Ceramics Aims and scope

Conclusions

  1. 1.

    It was established that the optimum conditions of chemicothermal treatment of phosphorus copper powder particles in solid-phase baths of boron, titanium, and nickel powders are, respectively 4 h at 800°C 4 h at 800°C, and 4 h at 600°C.

  2. 2.

    A study was made of the effects of titanium, boron, and nickel on the physicomechanical properties of porous phosphorus copper compacts. Titanium, boron, and nickel lower the hardness of phosphorus copper powder particles. Porous compacts made from phosphorus copper powder subjected to appropriate chemicothermal treatment conditions have higher hardness and strength at unchanged residual porosity. Their electrical resistivity is lowered by a factor of 1.5–2 compared with that of porous compacts from untreated phosphorus copper.

  3. 3.

    It was found that boron, titanium, and nickel reduce the coefficient of friction of a porous skeleton to 0.1–0.15, stabilize the values of this coefficient, and dimmish the extent of seizure of compacts in operations: against steel.

  4. 4.

    A hypothesis is advanced that boron, titanium,andnickel phosphides form in the copper.
