Corrosion resistance of Cerium based Silane-zeolite coatings on AA6061 alloy Angela Caprìa*, Luigi Calabreseb, Lucio Bonaccorsic and Edoardo Proverbiod Department of Electronic Engineering, Industrial Chemistry and Engineering, University of Messina, Contrada di Dio, 98166 Messina, Italy aangcapri@unime.it, blcalabrese@unime.it, clbonaccorsi@unime.it, deproverbio@unime.it Keywords: sol-gel; silane; zeolite; cerium nitrate; coatings.
Furthermore zeolites, thanks to their highly porous crystalline structures, can act as nanocontainers of inhibitors ensuring a controlled-release of cerium ions [6].

Introduction Sulfa (Sulfanomides SAs) is a general term for a class of drugs having the structure of amino-benzenesulfonamide.

Therefore, the formation of polymeric structure would be better.

The sample preparation and experiments were performed at Industrial Chemistry and Environmental Engineering Faculty of Politehnica University Timisoara.
White layer a b TiAlN layer White layer c Fig. 2: Micrographs of: a – untreated samples; b – nitrided samples; c – Duplex treated samples [Nital 2%, 500X] The microscopic examination of the untreated samples reveals a typical fine sorbitic structure, as it can be observed in Fig. 2a.

This result attributes that porous structure in AC can make easy the mass transfer of RB 49 and ozone molecules which increases oxygen-containing functional groups or active site for dye degradation.

Types of Pipeline Equipment of the Ventilation System from PCM, Produced in the World The types of pipelines made of PCM from different manufacturers can be divided into four groups according to the following features [6]: 1) type of binder (matrix): epoxy, polyester, polymeric; 2) type of fiber and reinforcement; 3) type of pipeline equipment connection: glue (one-piece) or mechanical (socket-nipple, bandage, flange); 4) piping wall construction: pure PCM (without lining), PCM with a film layer (lined pipes), multilayer structures.

The structures of the synthesized products were characterized by X-ray diffraction analysis (XRD; D8 Discover, Bruker AXS) using CuKα radiation at 40 kV.

Another effect which is driven by contaminants out of the container is metal corrosion for aluminum or copper wires within the microchip structure which is detected during defect density inspections.
So, the idea was to check the FOUPs especially if organic chemistry is used like within the litho process or the thin wafer flow for the AMC level.
