In metal additive manufacturing, surface roughness can make or break a part’s performance, from sealing to fatigue life. Researchers are mapping how process parameters, materials, and post-processing ...

Three new surface finishes for as-cast formed concrete are defined in the new ACI 301-10 Specifications for Structural Concrete, which supersedes ACI 301-05. Rough-Form and Smooth-Form As-Cast ...

EDITED BY CHARLES BATES SENIOR EDITOR An easy way to convert metric surface call outs to standard U.S. ones (rms) is to mentally multiply the metric value by 40. For example, 1.6 = 63 rms, 3.2 = 125 ...

Irregularities on a surface determine how rough it is. Surface roughness can be evaluated by visual appearances and tactile sensation and can be measured using a numerical scale. A surface condition ...

Surface roughness refers to the fine texture of a part’s surface. Every manufactured part’s surface has three main components—form, waviness, and roughness—that influence how well a part performs. The ...

With improvements in technology enhancing people’s lives, electronic products requirements have become greater in terms of being lighter, thinner, smaller, higher performance, and having more ...

Surface roughness influences many mechanical properties, including friction and adhesion, surface reactivity, semiconductor substrate quality, and surface interaction with electromagnetic waves, ...
