Abstract(J)	アルミニウム合金の環境水素に由来する脆化を抑制するためには，表面改質により合金新生面と水分との反応を遮断することが鍵になる。本研究では，アルミニウム合金の水素脆化感受性に対する表面不動態酸化膜の役割を明確にするとともに，水素脆化感受性の改善につながるめっきによる表面改質を調査した。 Translation
Abstract(E)	To suppress the hydrogen environment caused by atmospheric hydrogen of high-strength aluminum alloys, it will be important to block the reaction between the alloy surface without oxide film and water by modifying the surface. In the present study, effect of surface modification by plating on environmental hydrogen embrittlement of aluminum alloys was studied.

About search

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.

If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).

Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.

Example) X AND Y → "X and Y (including)" X OR Z → "X or Z (including)"

If AND and OR searches are mixed, OR search has priority.

Example) X AND Y OR Z → X AND (Y OR Z)

If AND search and multiple OR search are mixed, OR search has priority.

Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.

The number in "()" after each item is the number of data that includes that item.

Search tips

When searching by author name, enter the first and last name separated by a space, such as "Taro Jidosha".
