Joint Effect of Surface Microtopography and Near-Surface Structure on Microcontact Conditions: (Quarterly Progress Report, November-December 1988 and January 1989).

摘要

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 literature on the analytical determination of the deformation of layered half spaces by an axisymmetric rigid indentor have been recast in the form of correction factors wherewith a microcontact analysis of coated rough surfaces can be performed using simulation. 2 refs., 3 figs.
