2025 JSAE Automotive Engineering Exposition High density and high strength machine parts, sintered brazed joint products, laser hardened products
- Mechanical components are made using Fe-Cu-C based high-strength materials.
- The compact piece and brazing material are sintered together, and sintering and joining are performed simultaneously.
- Laser hardening components are irradiated on the surface with a laser, causing rapid heating and self-quenching, which transforms the surface into a martensitic structure for increased hardness.
