Magnesium Alloy Introduction AZ31B Magnesium Alloy Bar anticorrosion properties improvement via a novel surface treatment method. In this regard, the praseodymium (Pr)-based film formation on the Mg-alloy surface at different film formation conditions (i.e., pH, time, temperature) were investigated. The composition of the generated Pr-based film on the Mg-AZ31 alloy surface was characterized in depth using atomic/microscopic level techniques, i.e., X-ray photoelectron spectroscopy (XPS), atomic force microscope (AFM), X-ray diffraction (XRD), field emission scanning electron microscope (FE-SEM), and contact angle (CA) test. Chemical composition Pictures Quality Assurance 1. Checking raw material before producing. 2. Checking one by one before the assebling 3. Checking one by one during the production 4. Have the random inspection before the delivery. Packing & Delivery Packing Details : Standard Sea Worthy Pack.
