<p>A method of forming a metal product. The attributes of a final workpiece product are selected (step one). An appropriate substrate composition is determined depending on the selected attributes (step two). A workpiece substrate is formed to near finished dimensions (step three). An appropriate coating material composition is determined depending on the selected attributes (step four). The workpiece substrate is prepared for a high-density coating process (step five). The high-density coating process, such as HVOF thermal spray, is performed to coat the workpiece substrate with the coating material (step six). The coating material is built-up to a thickness effective to obtain desired finished dimensions after performing a hot isostatic pressing treatment. The appropriate hot isostatic pressing treatment parameters are determined (step seven). The hot isostatic pressing treatment is performed on the coated workpiece substrate to obtain a metal product having the desired finished dimensions and diffusion bonding between the coating material and the workpiece substrate (step eight).</p> |
