Conclusions
The next steps in developing SSF will require sufficient funding to produce samples with the suggested refinements and evaluate these samples. The steps include developing a proprietary auxiliary process that renders the annealing step unnecessary and allows for the direct use of the near-net shape in the assprayed condition, investigating specially prepared strengthening phase powders that better match the mechanical impedance of aluminum for producting near-net-shape aluminum MMC, using heated air as an accelerating gas, and conducting additional mechanical tests of aluminum and aluminum MMC to determine material properties.
After this work is completed, a production-prototype SSF system must be manufactured. Finally, to complete the SSF commercialization process, either a production facility or agreements with contract producers will be required. Innovative Technology anticipates that the SSF technology will also be licensed for use in various manufacturing plants. While it is too early to estimate the cost of these tasks, they will be considerable. The feasibility of such an expense will be evaluated on the basis of preliminary technical results, the market opportunity that the technical results suggest, and market-penetration estimates.
