ABSTRACTAmorphous “Diamond-like” carbon films were deposited on plasma-free substrates at low temperature by the Facing Targets Sputtering (FTS) method. Tribological characteristics determined by tap, scratch and slide tests were much better than those for amorphous carbon films deposited by the conventional Magnetron Sputtering (MS) method. Consequently, these films deposited by the FTS method were surely useful for protective layers in rigid magnetic disk.

Different Temperatures

Diamond-like carbon films were deposited on silicon (111) substrates at different temperatures using a pulsed-laser deposition method. Vickers indentation was used to measure the fracture toughness of the deposited diamond-like carbon films. It is found that diamond-like carbon films deposited at low temperature (55°C and 100°C) were very brittle and the fracture toughness was a difficult parameter to measure. The fracture toughness of diamond-like carbon films deposited at 270°C increased with film thickness and the measured values were between 1.0 and 2.3 MPa m 1/2.

Martensite Structure

It is well known that a number of compound superconductors with the A15 structure undergo a martensite transformation when cooled to the superconducting state. Nb3Sn is one of those compounds that transforms, at least partially, from a cubic to tetragonal structure near 43 K. To our knowledge this transformation in Nb3Sn has not been studied by TEM. In fact, the only low temperature TEM study of an A15 material, V3Si, was performed by Goringe and Valdre over 20 years ago. They found the martensite structure in some foil areas at temperatures between 11 and 29 K, accompanied by faults that consisted of coherent twin boundaries on {110} planes. In pursuing our studies of irradiation defects in superconductors, we are the first to observe by TEM a similar martensite structure in Nb3Sn.Samples of Nb3Sn suitable for TEM studies have been produced by both a liquid solute diffusion reaction and by sputter deposition of thin films.
