Outline of Research at the Start

機械摺動部の真実接触部の摩擦界面温度を直接計測可能な高い耐摩耗性と感度を兼備した温度センサ素子がないため、優れた電気伝導性・自己潤滑性を示す軟質金属(SMe:Au、Ag、Cu)と高い耐摩耗性を持つDLCをナノ構造複合化したSMe/DLCナノコンポジット膜(SMe-DLC)の構造最適化を図ることで、二つの素材が持つ高い自己潤滑性のシナジー効果によって高耐久性in-situ摩擦界面薄膜温度センサ素子を創製する。そのため、SMe-DLCの組成・ナノ構造と抵抗率の温度依存性および摩擦・摩耗特性の関係を明らかにし、SMe-DLCの温度センサ機能と摩擦・摩耗特性を最適化すると共に、その評価法を確立する。

Outline of Final Research Achievements

A deposition method that can prepare a soft metal/diamond-like carbon nanocomposite film (SMe-DLC) controlled over a wide range of the composition ratio of gold (Au), silver (Ag), and copper (Cu) has been demonstrated. We investigated the relationship between the concentration of SMe in the SMe-DLC and the structure, mechanical properties, and clarified the relationship with the friction and wear properties. As a result, it was demonstrated that the friction/wear properties and electrical properties in the atmosphere could be optimized by changing the SMe content in the film.
We also proposed a method to quantitatively evaluate the amount of wear due to SMe-DLC with a film thickness of less than 1 μm using a transmission electron microscope (TEM), and have developed a four-terminal probe type resistivity measurement apparatus for determining temperature dependency of electrical conductivity under various atmospheres.

Academic Significance and Societal Importance of the Research Achievements

SMe-DLCの組成・ナノ構造と抵抗率の温度依存性および摩擦・摩耗特性の関係を明らかにし、SMe-DLCの温度センサ機能と摩擦・摩耗特性を最適化すると共に、その評価法を確立する。トライボロジーとデバイス工学を融合した本研究課題の推進により、実働機械の複雑な運転状態における摩擦過程をリアルタイムで最適化し、機械摺動部の摩擦によるエネルギー損失を最小化するためのトライボロジーシステム設計技術の確立に資する。
