The Research Progress on Preparation of Al-Ti Alloy

Al-Ti alloys are widely used in various fields due to their excellent properties. There are mainly four production methods for Al-Ti alloys, namely direct dissolving method, sintering method, reduction method and electrolytic method. The first three preparation methods all have high-temperature melting steps, which increase energy consumption and production costs, generate hydrogen evolution or segregation, and reduce the quality of the Al-Ti alloy coating. There are three types of electrolysis systems, namely organic solvent systems, ionic liquid systems, and inorganic molten salt systems. Apart from the inorganic molten salt system, the organic solvent system and the ionic liquid system have the advantages of lower energy consumption, lower production cost, and uniform Al-Ti alloy coating prepared by electrolysis. Among them, the ionic liquid system has good chemical stability, good thermal stability, low energy consumption, and can be recycled.
