Precision casting silicon soluble facial layer process

Precision casting silicon -soluble facial layer process is a commonly used surface treatment process to improve the surface quality and performance of the casting. This process mainly includes the following steps:

1. Casting preparation: First, clean and rust removal of the treatment of the treatment of the processing is needed to ensure that the surface is clean and there is no impurities.

2. Coating silicone solution: Apply silicone solution on the surface of the casting, can be performed by spraying, immersion or brushing. After coating, it is necessary to dry, and it is usually dry or dry.

3. Silicon -soluble gel: Place the castings coated with silicon -soluble in the constant temperature environment, so that the silicon -soluble reaction occurs. Gel time and temperature are controlled according to the type and requirements of silicone solution.

4. Silicon -soluble sintering: Put the gelized casting into a sintering oven for sintering treatment. The sintering temperature and time are controlled according to the type and requirements of silicone solution, usually above 1000 ° C.

5. Silicon -solid annealing: The casting after sintering needs to be annealing to eliminate internal stress and improve the mechanical properties of materials. The temperature and time of the annealing temperature and time are controlled according to the materials and requirements of the casting.

6. Surface treatment: The surface of the casting of the silicon -soluble process will become smooth and uniform, and it has a certain wear resistance and corrosion resistance. As needed, further polishing, spraying and other surface treatment can be performed.

The precision casting silicon -soluble facial layer process can improve the surface quality and performance of the casting, so that it has better wear resistance and corrosion resistance, and is suitable for components and components in various industrial fields. At the same time, this process can also improve the size accuracy and surface smoothness of the casting, and improve the overall quality and reliability of the product.
