Surface treatment was conducted on aluminum alloy, ADC 12, by chemical tin plating, electroless nickel plating, electroless nickel plating (hardening), molybdenum disulfide coating on zinc phosphating, and hard anodizing; and on aluminum alloy, ADC 7, by hard anodizing. Then, the surfaces of above treated alloys were combined with steels, FC 15, S 15C, and S 15C (hardening), and subjected to wear tests to study the effects of surface treatment.The results obtained were summarized as follows:(1) Hard anodizing showed the most remarkable effect and electroless nickel plating (hardening) showed the second.(2) The treatment by hard anodizing was easier to conduct on ADC 7 than on ADC 12, and the wear resistance after treatment was higher in the former than in the latter. It was found that the hardness of the surface treated by electroless nickel plating was increased by heat treatment and its wear resistance was also improved. However, little effects were shown by soft and thin films such as treated by molybdenum disulfide coating and chemical tin plating.(3) When 3 kinds of steel materials, FC 15, S 15C, and S 15C (hardening), were combined with surface treated aluminum alloys, the tendency to toward wear resistance was nearly the same.

東日本大震災による東京電力福島第一原子力発電所での事故に対応して,一般の住民が生活の中での放射線量を計測するための放射線線量計“D-シャトル”を開発した。この線量計は,小型軽量で,各個人が携帯して必要に応じて表示器で記録を見ることができ,1年以上動作し,ユーザーの電池交換が不要である。本稿では,“D-シャトル”線量計の開発の経緯と機能について紹介するとともに,リアルタイムモニタリングへの応用についても紹介する。
