19.5年 (19年6ヶ月) 海洋曝露された無防食普通裸材 (アングル材) を対象にして，レーザ式表面形状測定装置を用いて精密な腐食形状計測を行い，腐食形状および板厚分布を把握した．これらのデータから海上部，飛沫帯，干満帯，海中部の腐食損傷度に関して，計測ピッチの違いによる表面形状の再現性を明らかにした．さらに，過去の計測データである2.5年，5.5年，9.5年，14.5年経過時のマイクロメータによる計測結果と対比させながら腐食形態と腐食速度の関係を明確にし，板厚計測する測定箇所の設定および板厚評価法の基礎資料を提供した．
The Fe-Pd ferromagnetic shape memory alloy is a multifunctional material. We investigated the behavior of the superelastic properties of rapidly solidified Fe-Xat%Pd (X=29.3, 29.6, 30.2 and 30.4) alloy ribbons to develop biomedical materials applicable to orthodontics and medical instrumentation. The appearance of a s…
Diamond-like carbon (DLC) is being advanced as an excellent surface modification technology for a growing number of applications because of its low friction coefficient and excellent wear resistance. Due to the excellent characteristics of certain mechanical elements, such as a bearing, high levels of functionality ar…
We prepared nanorods of octabutoxyphthalocyanine (ObPc) with an average diameter of 200 nm by filling porous alumina with molten ObPc. During solidification of ObPc in the porous alumina, a magnetic field of 5 T was applied to orient the ObPc molecules in the nanorods based on the diamagnetic character of ObPc. X-Ray…
The polymerization of cyclic esters such as Epsi-caprolactone (CL), L-lactide (LA) and Beta-butyrolactone (BL) was investigated in the presence of hydroxyl-containing polymers in dimethyl sulfoxide (DMSO) / tetrabutylammonium fluoride (TBAF). Although CL and LA did not polymerize in DMSO/TBAF solution in the absence o…
Abstract By using electrochemical techniques, the corrosion resistance of polyaniline (PANi)‐coated 1Cr18Ni9Ti stainless steel was investigated in simulated proton exchange membrane fuel cell (PEMFC) anodic environment. The results indicated that the compact conductive PANi film could be obtained on 1Cr18Ni9Ti steel b…
A major distress problem in rigid concrete pavements is early deterioration of near-surface layers. The quality of near-surface material governs the long-term performance of concrete pavement. If the near-surface material of the concrete layer is cured sufficiently well at an appropriate moisture and temperature, the…
Bio‐based polymers offer an alternative to conventional fossil fuel‐based materials, in particular for commodity applications such as single‐use products. In this work, we report on the rheology and processing of two bio‐based polymers, namely poly‐hydroxyalkanoate (PHA) copolymers and poly‐lactic acid (PLA), and thei…
We present our last results on proton nuclear relaxation dispersion data of water in plaster pastes in various conditions of water to plaster ratio (w/p) and temperature. These data have been interpreted with an intramolecular relaxation model involving elementary time steps of water near the interface (e.g. bulk brid…
Poly (trimethylene terephthalate) (PTT) nanocomposites with multi walled carbon nanotubes (MWCNTs) have been prepared by a simple melt compounding using DMS microcompounder. The non‐isothermal melt crystallization behavior of PTT in the presence of varying amounts of MWCNTs was investigated using DSC technique. An inc…
Results regarding the development of Lake Rėkyva (Lithuania) are presented. Radiocarbon dating, pollen and diatom analysis enabled to reveal Late Pleistocene and Holocene conditions in the lake and its environs. Lake Rėkyva sediments were drilled from the ice surface. Organogenic sediments occur in a 2-m thick layer.…
We consider the promising properties of very simple Diffractive Optical Elements (DOE) for reshaping the intensity profile of a laser beam. The first type of DOE that we have considered is a phase aperture which consists in a transparent plate with a circular relief introducing a π phase shift in the central region of…
Sensors for temperature detection can be achieved with platinum films. After these metallic films have been fabricated, measurements of the electrical resistance will correspond to the temperature of the film. Although metals have a well characterized temperature‐resistance relationship, this relationship changes if o…
In recent years there is a trend in industry to limit the usage of chemical compounds. Natural polymers are new promising materials that possess important properties like biodegrability or lack of toxicity. Radiation processing of natural occurring polymers is an area of current research for development of new applica…
The results of the development of modal liquid crystal wavefront correctors are reviewed. The modal principle of control is described. Characteristics and examples of application of electrically and optically controlled lenses and multichannel correctors with a tunable response function in different systems are report…

This paper provides a brief review of the (mainly in-situ) electrochemical methods that have been applied to coatings to assess corrosion protection ability. It discusses particularly the electrochemical noise measurement (ENM) which although still being developed has shown considerable promise as a method for assessi…
Gears made from Case-carburised SAE8620H steel were subjected to contact fatigue testing at different contact stress levels in the Gear Test Rig facility at Newcastle University. The High frequency Magnetic Barkhausen Noise (MBN) measurements were made at different intervals of fatigue cycles. The MBN signal level gra…
The Sichuan Basin is one of the most representative basins in Cretaceous terrestrial basin, in which a suite of red clastic deposition, especially gypsum and desert facies had been widely deposited. Based on previous study, climate marker of clay minerals, composition of the rocks, this study discusses climate and its…
A three-dimensional needled carbon fiber reinforced silicon carbide(3D needled C/SiC)ceramic matrix composite in the through-the-thickness direction was fabricated by the chemical vapor infiltration process.The resulting composite has a bulk density of 2.15 g/cm~3 and an open porosity of 16%.The adjacent layers for th…
