Laser hybrid fabrication of tunable micro- and nano-scale surface structures and their functionalization
M. Zhong; T. Huang Tsinghua University, Beijing, China
We introduce a novel laser processing-dealloying hybrid approach for tunable surface micro-nano structures. We used a high-power laser to deposit a CuMn alloy layer onto an engineering material surface, then fined its microstructure, and finally introduced a chemical dealloying process. Three kinds of micro-nano structures can be fabricated: nanoporous Cu structure, three-dimensional manganese-based nanoporous structure, and micro-nano hierarchical Cu/Cu2O structure. Their dimension is tunable via laser processing and dealloying parameters.
The fabricated micro-nano ...
