| Popis: | Porous layer on an aluminum alloy (A5052) sheet for joining with a Polyamide-6 (PA6) sheets was synthesized using combustion reactions among Al, Ti, and C powders. The laser was irradiated on the bedded powder blend of Al, Ti and C to induce the combustion reactions. The porous layer consists of a number of particle-shaped protrusions. Phase identification and microstructural observation of the cross-sectioned porous layer showed that the protrusions consisting of α-Al, TiC and Al3Ti phases, bonded well with the Al sheet. Single lap joints with PA6 and Al sheets via the porous layer were fabricated using a hydraulic hot press; PA6 infiltrated into the gaps among the particle-shaped protrusions. Fractography analysis indicated that the particle-shaped protrusions well interlocked with PA6, which resulted in a high-joint strength along with high reliability. ファイル公開：2021-08-01 |
