Abstract(J)	既存の耐摩耗性Co-Mo-Cr-Si合金で重要なLaves相型Co-Mo珪化物の結晶性、硬度、酸化特性を参考にコールドスプレーバルブシート向け耐摩耗性Fe-Mo-Si合金を開発した。Laves相型Co-Mo珪化物で報告されてきた酸化特性はμ相型のFe-Mo珪化物でも現れ、Co-Mo-Cr-Si合金同等の耐摩耗性が得られることを確認した。 Translation
Abstract(E)	Based on the crystallinity, hardness and oxidation properties of Laves phase type Co-Mo silicide, which is important in current wear-resistant Co-Mo-Cr-Si alloys, we developed wear-resistant Fe-Mo-Si alloys for cold spray valve seat. The oxidation characteristics reported for the Co-Mo Laves phase also appeared in μ phase type Fe-Mo silicide, and it was confirmed that wear resistance equivalent to Co-Mo-Cr-Si alloy was obtained.

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".
