Abstract(J)クランクジャーナル試験機を用い、アルミニウム合金すべり軸受とDLCコートジャーナル間の摩擦特性を調査した。DLCは鋼ジャーナルに対し、流体潤滑域で約14%の摩擦低減が測定された。単体ブロックオンリング試験機でも同様の効果が認められたことから、実際のクランクジャーナルにおいてもDLCによる摩擦低減効果が得られることが明らかとなった。

Translation

Abstract(E)The friction properties between the plain aluminum alloy bearing and the DLC coated journal were investigated using the crank journal tester. The DLC journal reduced friction by approximately 14% under the flied lubrication range compared with the steel journal. Since the same effect was observed by the block-on-ring friction test, it is clarified that the effect of reducing friction by DLC for the actual crank journal can be obtained.

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.
