Abstract

The compositions and powder technology for producing dispersionhardened bronzes of the system Cu—Ni—Si, Cu—Co—Si were developed. The mechanical properties and hot hardness of obtained materials were investigated at the temperatures of 20—600 °C, the laboratory tests welding were carried out. Wear resistance by contact welding of these materials exceeds that of known welding bronze of the type Cu—Ni—Cr and Cu—Cr—Nb—Zr. Full text download
