Experimental compositions of composite bronzes reinforced with dendrites from maraging steel 00NiCo9Al1 (BrFeNiCoAl 23-8-3-1), the properties of which can be controlled over a wide range, have been developed. The dispersion of dendrites in these bronzes can only be controlled by the crystallization rate of the corresponding melt. Bronze BrFeNiCrSi 12-7-5-1 reinforced with stainless steel dendrites, always “coated” with a solid (HV > 600) oxide film (Fe, Cr, Si)2O3 which does not adhesively interact with the counterbody—steel C 1%, Cr 1.5%, HRc 45, and this is the supporting friction surface (Charpy–Bochwar). All this provides bronze with extremely high wear resistance −0.001 μm/km, which is an order of magnitude higher than that of known prototypes. An increase in the dispersion of dendrites for all the studied bronzes significantly increases their tribological properties. Heat treatment of castings made of composite bronzes and surfacing is not required. There are no analogues similar to those considered. © 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG.
