Summary Of Experimental Bridge Features, Theodore Hopwood Ii, James H. Havens, Edgar E. Courtney

Kentucky Transportation Center Research Report

Experimental bridge features and service problems investigated during this study are reviewed. Those were epoxy-coated reinforcing steel, stay-in-place forms, experimental deck features (rotary compaction and broomed deck finishing), precast segmental bridges, steel-corrosion control methods (weathering steel and hot-dipped galvanizing), microsilica concrete, failures of masonry coatings, and failures of aluminum guardrail-retaining nuts.

Several features including latex and low-slump overlays, epoxycoated reinforcing steel, and broomed deck finishes (for state-built bridges), are now in common use. Most of the other experimental bridge features were performing satisfactorily. A corrosion problem was observed on one weathering steel bridge. Analyses of failures of masonry coatings and …

Growth Of Anodic Al2O3 Films, Bruce Parmelee

Journal of the Microelectronic Engineering Conference

The anodic oxidation of Aluminum (Al), which is a low temperature process, was used to form an aluminum oxide (Al₂O₃) film for use as an insulating layer. The anodization was done in a diluted, approximately 10% by volume, sulferic acid solution (H₂SO₄). Constant anodization voltages of 10, 15, and 20 volts, were maintained to obtain layers of Al₂O₃ ranging in thickness and refractive index from 3375-4077A and 1.46-1.95 receptively.
