THERMAL DIFFUSION (THE TD PROCESS) IS A HIGH TEMPERATURE SURFACE MODIFICATION PROCESS THAT FORMS A CARBIDE LAYER ON CARBON-CONTAINING MATERIALS (0.3% MIN.) SUCH AS STEELS, NICKEL ALLOYS, COBALT ALLOYS, AND CEMENTED CARBIDES, AND DRAMATICALLY HARDENS THE SURFACE OF THE MATERIALS TREATED. TD-PROCESSES MATERIALS EXHIBIT PROPERTIES OF CARBIDES AND NITRIDES; HIGH HARDNESS AND EXCELLENT RESISTANCE TO WEAR, SEIZURE, AND CORROSION.
