| Abstract(J) | 積層めっき被膜による耐疲労性向上を目的として，下地の結晶粒による組織制御を検討した．下地結晶粒は金属添加量により微細化でき，積層する被膜の結晶粒にも影響を及ぼす．下地の結晶粒制御によって応力分散や亀裂進展の挙動に変化し，すべり軸受性能の向上に寄与する可能性を示した． Translation |
| Abstract(E) | With the aim of improving fatigue resistance for multilayer plating, we examined the control of the substrate microstructure by grain size. The grain size of the substrate can be reduced by changing the amount of metal added, which also affects the grain size of the multilayer plating. The study showed that controlling the grain size of the substrate can change the stress dispersion and crack progress behavior, potentially contributing to improved bearing performance. |
