Conclusions
-
1.
As the matrix of sintered frictional bronzes, the ternary system Cu-Al-Sn (with appropriate additions) ensures much better service characteristics than do the corresponding binary systems.
-
2.
The best frictional and wear properties are exhibited by materials based on single-phase bronze whose matrix is alloyed with Al and Sn in the ratio 2.5∶1.
-
3.
In the solution of some practical problems in powder metallurgy, use should be made of the method of extremal experiment planning, which offers a number of distinct advantages.
