An ultra-high strength steel based on Fe-3Cr-0.4C for structural and abrasive applications has been designed and its structure-property relationships have been established. The microstructure has been characterized as dislocated lath martensite containing fine carbides and surrounded by thin films of retained austenite. This results in excellent ...

A 157 nm F2 laser was used for the surface and interface modifications of Al thin films on silica glass substrate for fabricating a pattern of Al thin films. The F2-laser irradiated surface swelled remarkably by inducing the strong oxidation reaction of Al thin films to ...
In this study, the physical performance (adhesion resistance, heat resistance, abrasion resistance, chemical resistance) extremely thin, highly durable and chemically adsorbed fluorocarbon film with low surface energy on the metal surface (the thickness is about 1 nm order.) was evaluated, and the evaluation ...
The use of copolymers of pentaerythritol triacrylate and trimethylolpropane triacrylate, respectively, with various acrylic or vinyl monomers in radiation curing for the preparation of abrasion-resistant coatings was studied. Pentaerythritol triacylate systems exhibited higher viscosities, faster photoresponse and better abrasion-resistance than the equivalent ...
Plasma-polymerized vinyl trimethoxy silane films were deposited on transparent polycarbonate substrates. The adherent, clear films protected the substrates from abrasion and also served as antireflection coatings. Post-treatment of the vinyl trimethoxy si...
The structure-property relationships of an ultra-high strength steel with a chemical composition that was based on Fe-3Cr-0.4C are described. The microstructure, which consisted of dislocated lath martensite containing fine carbides and interlath thin films of retained austenite, was found to give combinations of mechanical properties and ...
To evaluate the coating damage caused by pulling pipelines over coral and sandstone seabeds, abrasion field tests were conducted on various coating materials - concrete, coal-tar enamel, extruded polyethylene, coal-tar epoxy paint, alumina-filled epoxy paint, and sand-filled epoxy coating - as well as on two types of joint coverings, the heat-shrinkable plastic sleeve and laminated pipe tape. The ...
Antithrombogenic films with high durability were fabricated in a wet process. Antithrombogenicity was achieved with polyelectrolyte multilayer thin film prepared from poly(vinyl alcohol)-poly(acrylic acid) (PVA-PAA) blends, deposited in alternate layers with poly(allylamine hydrochloride) (PAH). Film durability, ...
