Outline of Final Research Achievements

Austenitic stainless steel alloy-based tungsten carbide composite materials were obtained using laser metal deposition. This research aimed to improve the wear and corrosion resistances of the composite materials by low-temperature plasma nitriding, carburizing and continuous nitriding after carburizing.In the result, the expanded austenite phase (knows as S phase), which is a solid solution of excessive nitrogen or carbon dissolved in the fcc lattice, was formed on the stainless steel alloy parts in the composite materials.It is confirmed that the wear and corrosion resistances were improved due to the formation of the S phase. In addition,the effects of the composition of nickel, chromium, and molybdenum in stainless steel alloys on the properties of the S phase were examined, and the effects of metallurgical structure peculiar to laminated moldings on the S phase were investigated.

Academic Significance and Societal Importance of the Research Achievements

次世代のものづくりに対応するため,積層造形を導入する事例が増加しているが,最近は特に摩擦摩耗および腐食など過酷な環境下でも使用可能な材料の開発が求められている.ステンレス合金鋼/タングステンカーバイドの複合材料は有力な候補の1つであるが,さらなる特性改善が必要であった.本研究は,低温プラズマ表面処理の技術を利用することで,この複合材料の耐摩耗性と耐腐食性の両方の改善を実現した.さらに,ステンレス合金鋼の組成を低温プラズマ処理に最適化するのに必要な解明も行うなど,積層造形およびプラズマ表面処理の両方の技術の進歩に貢献できたと考えている.
