Abstract(J)ベアリング等の動的負荷環境における水素脆化事象は,発生メカニズムが不明確であり,決定的な結論には至っていなかった.本報では,オイル皮膜形成能に及ぼす添加剤の影響と,実使用環境における振動影響に着目し,メカニズム解明に取り組み,一定の結論を得た.また,実運用可能な水素脆化強度の判断指標を構築した.

Translation

Abstract(E)The mechanism of hydrogen embrittlement under dynamic loading, such as in bearings, has remained unclear, and no definitive conclusion has been reached. In this study, we investigated the effects of additives on oil film formation and the influence of vibration under actual operating conditions to clarify the mechanism and obtained meaningful insights. Furthermore, a practical indicator for evaluating hydrogen embrittlement strength applicable to real operation was established.

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.
