【 摘 要 】

In the 10th quarter no further work was conducted on the steel matrix composite element of this project. For this element work is effectively complete and all that remains is the composition of the final report. For the thermal spray coating effort, components coated and fused in the previous quarter were subject to high stress abrasive wear testing. Some complications were encountered with the wear testing, but the tests which were completed successfully showed that the coatings provided wear resistance 5x that of the baseline material. Further wear testing is planned for the 11th and final quarter. An overview of the progress during the 10th quarter of this project is given below. Additional research details are provided in the limited rights appendix to this report.
