About this document
Tungsten Carbide Coating for Feedscrews by Rodrigo Perea is a document available to read on EtoBox.
Tungsten carbide is used as a coating for feedscrews because it is one of the hardest and most economically viable materials that provides wear resistance. Tungsten carbide has a hardness of around Rockwell C 85 when combined with carbon. The coating being discussed contains up to 90% tungsten carbide by weight and over 80% by volume, making it extremely hard and abrasion resistant. Most wear resistant alloys contain less than 35% carbide concentration by volume, demonstrating how hard this coating is.
