In this study, we utilized Al2O3 nanoparticles (NPs) as an inorganic surface modifier to enhance the wettability and reduce the roughness of poly-bis(4-phenyl) (2,4,6-trimethylphenyl) amine simultaneously.

In this research, specially designed Al–Fe–Cr samples possessing an Al–Fe–Cr quasicrystal-reinforced Al matrix structure were manufactured using a laser powder bed fusion (LPBF) process. Based on the optimized process parameters of laser scanning speed and hatch distance, an almost dense (99.8%) free-crack sample was obtained with the multiscaled heterogenous structure induced by the nonuniform rapid solidification in a single molten pool. The results show that nanosized Al–Fe–Cr quasicrystalline particles of different sizes are heterogeneously distributed in the α-Al columnar grain structure. In detail, the coarse flower-like and spherical QC particles can be observed at the molten pool boundary, and the fine spherical Al–Fe–Cr QC is located inside the laser fusion zone. The orientation relationship between the Al matrix and the icosahedral Al–Fe–Cr QC is as follows: Al [ − 112 ] ∥ i5 with a semicoherency feature. The novel designed LPBF-processed Al–Fe–Cr alloy exhibits high mechanical strength due to the ultrafine multireinforced microstructure-induced Orowan strengthening effect.
