NITRIDED VANADIUM, COLUMBIUM AND TANTALUM BASE ALLOYS

摘要

A novel group of nitrided alloys having excellent wear and abrasion resistance containing as their major constituent at least two metals of the group columbium, tantalum and vanadium alloyed with titanium and/or zirconium. Such alloys are fabricated to shape and are then nitrided to produce high-surface hardness thereon. The nitrided alloys have utility as cutting tool materials and other areas of use where excellent wear and abrasion resistance are desired.
