金属3Dプリンターを活用したバイオミメティツク・トライボシステムの創製

抄録

We proposed a novel tribo-system, which has "Material feed path" beneath the sliding surface to control tribological properties by supplying materials such as additives via the paths. The sliding specimen with "Material feed path" were manufactured by utilizing a metal 3D printer. Base oil and additives (MoDTC, ZnDTP) were supplied through "Material feed path" during sliding test. In summary, friction coefficient reduced by supplying additives to sliding surfaces via "Material feed path". It is suggested that the "Material feed path" could be one of the methods to active-control the tribological properties.
