| Abstract: | Conclusions A study was made of the room-temperature dry friction and wear of alloys of the systems ZrB2-ZrN and HfB2- HfN in air. It was found that all the materials investigated possess high wear resistance. The lowest values of coefficient of friction (0.3–0.4) and increased wear resistance at a sliding speed of 1 m/sec are exhibited by composites based on hafnium diboride and those containing 40–70 mole % zirconium nitride.Translated from Poroshkovaya Metallurgiya, No. 7 (103), pp. 63–67, July, 1971. |
