Extreme Coatings, St. Petersburg, Florida, is now offering a coating that transforms a standard steel blade into a carbide-edge blade. The company (which normally handles coatings for screws) markets the blade coating through WITAK, Inc. The coating is especially useful for processors dealing with tough materials. For example, it offers protection against calcium carbonate, which is often used as a filler material in plastic trash cans.

0.001-0.002 inch-thick CarbideX C1000 tungsten carbide coating on granulator and grinder blades provides a tougher -- more resilient cutting surface where blades require less frequent sharpening and have a greater service life.
