Patent 7922563 was granted and assigned to Blount, Inc. on April, 2011 by the United States Patent and Trademark Office.
A hard-faced cutting blade and hard-facing method is provided. A hard-facing material is applied to a cutting edge of a cutting blade such that a heat-affected transition zone may be created between the base metal and the hard-facing material. The heat-affected transition zone may create a sufficient bond to help resist delamination and flaking of the hard-facing material from the base metal.
