The assembly of ZSM-5 layer on Mg–Li alloy by hot-pressing using silane coupling agent as bond and its corrosion resistance

The synthesis of ZSM-5 (Zeolite Socony Mobile-Five) layer on Mg–Li alloy has so far proved difficult. Here we report an effective strategy to assemble ZSM-5 layer on Mg–Li alloy by hot-pressing, using silane coupling as a bonding agent. The high crystalline ZSM-5 showed that the hexagon crystals appeared to be attached firmly to the support. The corrosion behaviour, assessed by electrochemical measurements, showed that ZSM-5 layer reduced the corrosion activity of Mg–Li alloy. The hot-pressing served as an environmentally friendly, corrosion-resistant coating for Mg–Li alloy. The method can potentially provide a general route to synthesize various, uniform layers on other active metals.
