Oxide‐Free Titanium Coatings by Wire Arc Spraying in a Silane‐Doped Inert Atmosphere
Advanced Engineering Materials, EarlyView.A silane‐doped argon atmosphere enables the production of oxide‐free titanium coatings via twin‐wire arc spraying at ambient pressure. This innovative approach eliminates residual oxygen, creating process conditions that prevent oxidation and nitride formation.

Wettability of a Single Carbon Fiber
Langmuir, 2016 A new method was developed to measure the dynamic contact angles of a single carbon fiber at low and high velocities, taking into consideration both the intrinsic variability of the carbon fiber diameter and the extremely small amplitude of the capillary forces. The effectiveness of the method was strengthened by fitting the experimental contact angle ...

Effect of Laser Deoxidation on Adhesive‐Bonded Aluminum in an Oxygen‐Free Atmosphere
Advanced Engineering Materials, EarlyView.This study investigates laser ablation of aluminum under oxygen‐free conditions. The goal is to produce oxide‐free substrates that enable improved adhesive bonding with epoxy. Optimized laser parameters (90% overlap, 300 µJ) combined with oxide‐free substrates result in the highest tensile strength of the adhesive bond.

Journal of the Fuel Society of Japan, 1956 ぬれを支配するものは, ぬれの難易とぬれの界面の大いさとである。そこで, まず25℃おける各種石炭の水に対するぬれならびに共存する水と油とに対する選択ぬれの自由エネルギ変化を置換圧測定によつて求め, ぬれの難易を石炭の石炭化度と対比して考察した。つぎに, 25℃における石炭一水の吸着実験を行い, Banghamの式によって, 石炭の単位重量当りの表面自由エネルギ変化を算出し, 接着ぬれから求められた値と組合せて, 石炭の保有する界面の大いさを求めて考察を加えた。石炭のぬれの難易には, 炭素含有量78%および89%附近に転移点があり, 若年炭, 瀝青炭および無煙炭の3群にわけられる。また, 石炭化度の変化に件い, 水おおよびベンゼンに対し特徴的な傾向を示す。石炭の鮪する界面の大いさは ...

Removing Oxide Layers and Retaining Oxide‐Free Steel Surfaces by Polishing in Oxygen‐Free Atmosphere
Advanced Engineering Materials, EarlyView.In this study, the efficacy of wet mechanical polishing under an oxygen‐free atmosphere for deoxidation and the retention of an oxide‐free steel surface are elucidated using X‐ray photoelectron spectroscopy. The methodology proved successful; however, the results were highly dependent on the preparation of the solvents used to clean the samples after ...
