　　Anti-rust treatment of aluminum alloy die casting

　　Although the aluminum alloy die casting itself has good corrosion resistance, it is not immune to corrosion, especially in some special environments, in order to further improve the corrosion resistance of aluminum alloy die casting, so that it can meet the needs of customers, die casting manufacturers will also carry out anti-rust treatment for aluminum alloy die casting.

　　Engineering materials can be damaged or degraded by chemical or electrochemical interactions with the environmental media they encounter. For metals, the damage that occurs is called corrosion, commonly known as rust or rust. For non-metals, this destruction is called degradation or metamorphism. This is the definition of aluminum alloy die-casting corrosion, and rust prevention is the use of appropriate means and methods to reduce or prevent this effect.

　　Corrosion prevention of aluminum alloy die-casting is divided into permanent and temporary two kinds, permanent rust prevention means include electroplating, electroless plating, thermal spraying, coating, vapor deposition, etc. Temporary rust prevention is aluminum alloy die casting rust sealing package.
