Weld overlays are used extensively in areas of severe wear and corrosion. Current techniques for applying weld overlays, including MIG/TIG welding, laser welding, and PTA have limited throughput, and can result in degredation of the overlay properties due to substrate dilution and thermal degredation of the ceramic phases in the deposit. This paper will introduce and present current progress and status of Cermaclad, high energy density fusion claddings (overlays). The Cermaclad process utilizes a high intensity linear heat source to fuse and metallurgically bond overlays at areal coverage rates an order of magnitude (or more) greater than traditional weld overlay techniques. Due to the unique nature of the fusion cladding process, higher overlay purities and improved microstructrues can be obtained, improving wear and corrosion performance, potentially at lower cost and higher productivity than more established overlay techniques.
