... surface treatment to protect against corrosion induced by the buildup of chloride and sulfide salts typically found within distillation reboilers. Application on carbon steel test panels was completed using industry standard spray application methods and subsequently characterized for adhesion strength...

... rocking cells are employed to study gas hydrate nucleation and deposition. A bench-scale flowloop filled with crude oil and heptane is used to quantify the deposition of crude oil and asphaltenes after a set time period. Lastly, a mechanical shear device measures the adhesion force of wax deposits...

... would be preferable. Diamond Like Coatings (DLC) have shown considerable promise, but the industry remains skeptical in the absence of conclusive evidence. This work addresses the question for a novel super hydrophobic DLC with a parametric evaluation of factors affecting adhesion and growth of common...

The purpose of this project was to develop a multifunctional, omniphobic coating with superior substrate adhesion such that it could fill in and plug surface crevices and pits stemming from corrosion. Additionally, unlike most other coatings, this surface...

... stress. The total platform tip resistance force is obtained by integration over the skirt tip area. The difference between PIAPA and most other programs is that account is taken of the extra vertical stress due to heave and friction. PIAPA enables the input of arbitrary cohesion, adhesion and weight...

... was constructed with the following sections on site at the Santa Fe Apache base in Scotland: Field jointing was carried out by a contracted company using a cast polyurethane elastomer and a two component polyurethane elastomeric resin system. This system is compatible with neoprene coating (adhesion...

... at least 5 to 8 m, in order to be guided by the template sleeves during penetration into the soil and to provide sufficient adhesion (probably by groutin ) to transfer resisting Jforces to the template (Fig.2 . - Penetration of the superpile into the soil by self weight.

... which could be much higher. THEORY In the absence of indentations in the steel which produce a mechan- ical bond, the total bond strength between concrete and steel is a com- bination of chemical adhesion and · friction (1). The exact amount of adhesion and friction is not impor- tant to this study...
