Wear resistance of the chromium alloys with titanium, zirconium, hafnium, niobium and tantalum

摘要

The wear resistance during sliding was determined for the chromium alloys with titanium, zirconium, hafnium, niobium or tantalum alloying. The additions increase the wear resistance up to their maximal contents which 19 /100 Ti and 30-35 /100 other (eutectic compositions). The gains were shown with the data and phase diagrams comparative analysis to be more for single-phase alloys in (Cr) solid solution fields than for two-phases ones containing Laves-Phases. The metals are phased as Ti, Nb, Ta, Hf and Zr in wear-resistance of two-phases Alloys.
