This article describes the process and advantages of no-bond methods of vacuum molding and magnetic molding, with schematic illustrations. It also discusses the characteristics of plastic film and dimensional specifications of vacuum molding.

Anodizing is one of the most common surface treatments of aluminum and is performed for corrosion protection. This article describes the structure and growth characteristics of the types of anodic oxide films such as a barrier-type oxide film and a porous-type anodic oxide film. It discusses each step involved in the anodizing process of an aluminum or aluminum alloy specimen. The anodizing process includes pretreatments (degreasing, etching, and polishing), anodizing, coloring, and sealing. The article provides an observation of the morphology of the anodic oxide films by transmission electron microscopy and the scanning electron microscopy for testing properties of anodic oxide films.

This article discusses the properties and applications of two types of polyimide resins: condensation polyimides and addition-type polyimides. It describes the chemistry of condensation-type polyimides during synthesis, processing of polyamide acid precursor solution to polyimide, and preparation of polyimide films from thermoplastic polyamic acid precursors. The article reviews the chemistry of several addition-type polyimides, including phenylethynyl-containing imide oligomers, nadic end-capped polyimides, and LARC RP46. It explains the preparation processes of nadic end-capped amic acid oligomer resin solutions, including the preparation of resin powder and resin disks, adhesive film, adhesive bond specimens, and films.

This article describes the structure of coatings produced by plasma spraying, vapor deposition, and electrodeposition processes. The main techniques used for microstructure assessment are introduced. The relationship between the microstructure and property is also discussed. The experimental techniques for microstructural characterization include metallographic technique, X-ray diffraction, electron, microscopies, and porosimetry.
