This study investigates the filiform corrosion resistance of chromate-free coating systems fabricated on aluminum alloys by low-temperature plasma interface engineering. The aluminum alloys investigated include AA2024-T3 ([2B]), AA7075-T6 ([7B]), Alc

Large bubbles emerge from porous membranes with small pores because the emerging bubbles spread on the membrane surface before they detache from the surface. If the sessile bubble contact angle (θ) is less than 45°, no spreading occurs, and the bub

A continuous isothermal separation process was developed for components of olefin/paraffin mixtures. This process features a combination of two steps: absorption of olefin by silver ion in an aqueous solution at high pressure and isothermal regenerat

The adhesion failure of a primer on a plasma-polymer-deposited substrate surface could occur at the interface of the substrate/plasma polymer or at the interface of the plasma polymer/primer. We examined the adhesion of spray (solventborne or waterbo

DC cathodic polymerization of trimethylsilane (TMS) was carried out in plasma reactors with and without using anode assembly. In DC cathodic polymerization, the TMS plasma polymers are mainly deposited on the cathode (substrate) surface. As a result,

Plasma processes often go beyond the primary objectives focused on the substrate, or targeted materials. For instance, sputtered materials deposit on surfaces other than the substrate, and plasma deposition extends to the walls of the reactor. In the

A Prohesion salt spray corrosion test was carried out with 32 primer-coated AA2024-T3 (UNS A92024) test panels with four different kinds of scribes (eight test panels each). The scribing width and depth showed little effect on the test results. The e
