Graphite film by sol gel
WebFeb 15, 2024 · An active protective coating for Mg alloy can be produced by sealing a PEO layer loaded with a sol-gel [10,11] or epoxy coating. The coating offers high wear and corrosion protection. Mg alloys display relatively low coefficients of friction (COFs) because the hexagonal crystal structure of Mg permits shearing on the basal planes. WebJul 20, 2024 · To prepare uniform CZTS thin film and CZTS TFSCs, sol–gel solution was dropped on cleaned SLG and FTO substrates and rotated at 500 rpm for 20 s and further at 2000 rpm for 30 s. The as-synthesized CZTS thin films were then dried on a hot plate at 150 ºC for 20 min in air to remove carbon residues of organic solvent (2-ME).
