BrazeCoat for shear bars and knives.

An ultra-high density carbide coating that can be applied to shear bars (stationary knives) to improve their wear resistance and service life has been introduced by Lund Precision Products, Inc.

Lund BrazeCoat is an extremely dense, low porosity hardfacing material that can be applied in various thicknesses from 0.002" to 0.100" or more, with carbide densities up to 70% by volume, embedded in a metallic matrix. Metallurgically bonded to the base metal, the resulting coating can achieve over 65 Rockwell C hardness values to withstand abrasive wear, even in high impact applications, and is well suited for all types of stationary knives.

Applied in two ways, depending upon the desired coating thickness and wear requirements, Lund BrazeCoat is well bonded and shows a porosity of less than one percent. The actual coating particles can be either tungsten carbide (WC), chromium carbide (Cr3C2), or a combination thereof.

Applications include agricultural shear bars and construction, industrial and mining equipment.
