What are the main factors that cause corrosion metal machining accuracy

The precision of corrosion metal processing is mainly related to the following factors:

1. Type and concentration of corrosion solution: different types and concentrations of corrosion solution have different effects on the corrosion rate and corrosion degree of the metal. Generally speaking, the higher the concentration of the corrosion fluid, the faster the corrosion rate of the metal, but not necessarily applicable to all metals. Therefore, in the corrosion of metal processing process, according to the metal material and processing requirements need to choose the appropriate type and concentration of corrosion fluid.

2. Corrosion temperature and time: corrosion temperature and time are also key factors affecting the accuracy of corrosion metal processing. Within a certain range, increase the corrosion temperature can accelerate the corrosion rate of the metal, but too high a temperature will lead to oxidation and deformation of the metal surface, thus affecting the machining accuracy. At the same time, the corrosion time is also an important factor affecting the degree of corrosion of the metal, too long corrosion time may lead to excessive corrosion of the metal, thus reducing the machining accuracy.

3. The nature of the metal material: the nature of the metal material also has an important impact on the corrosion processing accuracy. For example, the hardness, toughness, purity and other factors of metal materials will affect its corrosion resistance. Generally speaking, the metal with high hardness is more corrosion resistant than the metal with low hardness, while the metal with high toughness is more susceptible to stress corrosion. At the same time, the impurities and alloying elements in the metal material will also have an impact on its corrosion resistance.

4. Processing technology and equipment: corrosion of metal processing technology and equipment will also have an impact on the processing accuracy. For example, the use of different processing technology and equipment will lead to different metal surface roughness, thus affecting the processing accuracy. At the same time, the processing of pressure, vibration and other factors may also produce small displacement and deformation of the metal, thus affecting the machining accuracy.

5. Environmental factors: environmental factors are also one of the factors that affect the machining accuracy of corroded metal. For example, humidity, oxygen concentration, carbon dioxide concentration and other environmental factors will have an impact on the corrosion rate of the metal, thereby affecting the machining accuracy.

To summarize, the precision of corrosion metal processing is affected by a variety of factors, including the type and concentration of corrosion fluid, corrosion temperature and time, the nature of the metal material, processing technology and equipment, and environmental factors. In order to improve the precision of corrosion metal processing, these factors need to be considered comprehensively, and take corresponding measures to control and manage. For example, selecting the appropriate type and concentration of corrosive fluid, optimizing the corrosion temperature and time, improving the purity and corrosion resistance of metal materials, adopting advanced processing technology and equipment, and reducing the impact of environmental factors on metal corrosion.
