joint effect of surface microtopography and near-surface structure on microcontact conditions: (quarterly progress report, november-december 1988 and january 1989)

pin-on-disk tests are now complete on 18 of the 27 ceramic phase i specimens. a total of 45 hardened m50 high alloy steel disks have been fabricated. three distinct surface finishes, having nominal values of 1, 3, and 10 microinch rms, have been applied to sets of 15 of these specimens. numerical results taken from a study found in the li..

acoustic-optic measurement of micromechanical resonance for adhesive bond integrity

traditional nondestructive evaluation (nde) of bonding flaws has generally used either ultrasound or x-rays as a directed energy source to image or otherwise detect the discontinuity of an improper bond. while this approach has broad applicability, it is inadequate where the material is highly attenuating or anisotropic, or when it is imp..

mechanical design of a rf electron gun

brookhaven national laboratory is building an accelerator test facility at which we plan to study laser acceleration of electrons, inverse free electron lasers and the production of x-rays by non- linear compton scattering. the facility contains an electron gun, linac, lasers and ancillary systems which will enable the production of 6 ps ..

influence of neuroendocrine mediators on phagocyte function. final rept. 1 jul 86-30 nov 88

the objective of this research program was to explore the effects of certain neuroendocrine mediators and macrophage function. treatment with met-enkephalin led to a flattened cell morphology with many linear and punctate microfilaments in the cytoplasm. these physical changes in cell structure were accompanied by dose-dependent increases..

experiments with three identical ultraprecision machine tools

this paper outlines the underlying philosophy of, and reports preliminary results from experiments with three nominally identical diamond turning machines. identical tools, specially fabricated from the same diamond, were used to machine mirrors from blanks cut from the same base material using previously specified process parameters; par..
