Abstract null null To investigate the growth characteristics and corrosion resistance of Micro-arc oxidation (MAO) coatings prepared from Al–Mg composite plates under sodium silicate electrolyte, comparative experiments were performed using single plate Al and Mg. The results showed that the breakdown of the Mg plate (P–Mg) in the Al–Mg composite plate occurred first than the Al plate (P–Al). The coating thickness of P–Al and P–Mg gradually converged with time. Because after the Al and Mg plates...

Abstract null null MoSi2/NbSi2 composite coating was prepared on Nb-based alloys through electrodeposition and halide activated pack cementation (HAPC) process. Preferred electrodeposition process, the effect of electrolyte with different concentrations of MoO42- on the electrodeposition behavior and coating formation were investigated. Besides, the microstructures of the composite coatings, and the hot corrosion behavior of the MoSi2/NbSi2 composite coated Nb-based alloys in the mixture of Na2S...

Abstract To decrease coefficient of friction (CoF) of the 6063 aluminum alloy modified by microarc oxidation (MAO) treatment, a MoS2 lubricating layer was synthesized on the MAO coating by hydrothermal reaction. The as-synthetized MoS2 powders demonstrated high purity and interesting micro-spheres structure assembled by many nano-lamellae. The prepared MoS2 layer was ~11 ± 3.3 μm thick, and padded the surface porosity of MAO ceramic coatings. These composite coatings were slidden against GCr15 s...

Abstract Structural defects such as micro-pores and cracks generated during the micro-arc oxidation process can greatly reduce the corrosion resistance of the coating. This work proposed a method to improve the anti-corrosion property of the micro-arc oxidation (MAO) coating by layer-by-layer (LBL) assembling a polyurea layer on the surface of it. Organic silane (KH) and isophorone diisocyanate (IPDI) were self-assembled alternately on the MAO coating surface and formed a polyurea layer. The ass...
