Title: Materials processing cylinder containing titanium carbide

Abstract: A bimetallic materials processing cylinder formed of a titanium carbide alloy via a vacuum melt process, for example at a pressure of about 10.sup.-4 Torr, the purpose of which being to utilize titanium as a main ingredient binded by the best available wear and corrosion resistant alloy that will ""wet"", but not dissolve too much as a cermet, to thereby create a metallurgically bonded inside layer of a material processing bimetallic cylinder. The titanium carbide alloy is for example up to about 58 volumetric percent titanium carbide and the remaining volumetric percent is a predetermined bonding alloy. Preferred titanium carbide alloys are (by weight percent): titanium carbide at 24.80 to 53.60%, nickel at 44.30 to 29.20%, chromium at 13.50 to 6.00%, silicon at 3.60 to 1.75%, boron at 2.85 to 1.75%, molybdenum at 3.70 to 1.38%, copper at 1.50 to 0.46%, iron at a 3.00% maximum, carbon at a 0.45% maximum, and other materials at a 2.00% maximum.
