Abstract : The contractor's technical proposal described the ultra-high vacuum mechanical microprobe recently installed in our laboratory, and designed to investigate sliding contact at the single asperity level. The project started on March 1st, 1984, since when we have appointed a postdoctoral research associate, Dr. J.D.J. Ross, who will work on this project for 2 1/2 years (from 1st June 1984, the date of his appointment), and whose salary is paid from the funds awarded. Dr. Ross worked with Dr. C.A. Brookes at the University of Exeter on size effects in hardness, deformation in diamond cubic solids, and the effects of sliding contact on the microhardness of bearing steels. Each feature of the microprobe has been made to function successfully with the help of certain specially-fabricated additional components. These features include the microprobe assembly itself, the ultra-smooth rigid sliding contact system, the field emission assembly, and the electron and ion beam systems. As described in the supplement (dated Oct 1982) to the technical proposal, the project also involves complementary work on the measurement of microhardness at sub-micron depths.
