Introduction: Titanium alloys containing the β phase have much better corrosion resistance. Some alloying elements, such as Mo, stabilize this phase. Among the Ti alloys that contain this element, the Ti-10Mo alloy is of particular importance. If this alloy is produced using selective laser melting (SLM), it will be an approach that is user-friendly due to the nature of the process. Methods: Samples were printed by SLM process. The constituent phases were determined by XRD. The microstructure was evaluated using optical and scanning electron microscopes.... by Arezoo Pourshoja, karim Avak, Maziyar Azadbeh, Mohamadreza Etminanfar, Mehdi Ojaghi

Performance Evaluation of Organic Anti-Corrosion Coating for Car Based on Electrochemistry by SU Jian, CONG Yu-feng, HUANG Wei, JIANG Chuan-dong

“…In order to deal with the corrosion problem of car cavity, an anti-corrosion organic coating for the inner cavity of a car was prepared to protect the inner cavity during corrosion during service.The performance of coatings was evaluated by high/low temperature test, thermal analysis, microstructure, wet heat test, salt spray test and electrochemical test.Results showed that the coating had good stability in high temperature(80 ℃, 24 h)and low temperature(-35 ℃, 8 h), and the film structure was compact.After 360 h under the conditions of high temperature and high humidity, and 120 h in salt spray environment, the corrosion resistance reached the industry standard level one.After immersed in 3.5%(mass fraction)NaCl solution for 96 h, the coating resistance still reached 3.14×106 Ω·cm2, indicating that the organic anti-corrosion coating had good anti-corrosion performance.…”
