チタン合金の海水中における耐摩耗性に及ぼす摩擦改質の影響

抄録

This research focused on friction-based techniques for modifying the wear properties of a titanium alloy, particularly under seawater conditions. The surface modification processes employed were powder intrusion and friction stirring. Three different kinds of powder materials were used for the surface modification: Cr₂N,TiN and Al₂O₃. Wear tests were conducted on the specimens under both dry and artificial seawater conditions. The results revealed that the Cr₂N modified material presents excellent wear resistance under dry conditions, whereas modification using Al₂O₃ and Zn-coated Cr₂N led to excellent wear properties under artificial seawater conditions.
