Applications of tantalum capillary tubes in coating industry

In the coating industry, tantalum tubes play an important role because of their excellent corrosion resistance, high melting point and good mechanical properties, especially in coating processes that require precision control and high durability. Here are some of the main application areas and advantages of tantalum pipe in the coating industry:

1. As a transport pipeline for electroplating solution
Tantalum capillary tubes are often used to transport highly corrosive electroplating solution such as sulfuric acid and hydrochloric acid during electroplating. These corrosive liquids are easy to cause pipeline corrosion in conventional metal pipes, and tantalum has a strong corrosion resistance and can be used in extreme environments such as strong acids and alkali for a long time to ensure that the electroplating solution will not be polluted or deteriorated due to the corrosion of the pipeline material, thereby improving the quality and efficiency of electroplating.

2. For high-precision transmission in electroless plating
The electroless plating process requires the transport of chemical solutions under very precise conditions, and the small diameter and high-precision manufacturing capability of tantalum tubing make it possible to precisely control the flow rate, pressure and other parameters of electroless plating solutions, thus ensuring uniform and fine coating. This is particularly important in the plating process of high-end electronic components, such as the electroless plating of chips and microelectronic devices, which requires a highly uniform coating to ensure the performance and life of the components.

3. For high temperature coating process
Tantalum has a melting point of up to 3017°C, which makes it possible for tantalum capillaries to be used for a long time under high temperature conditions and suitable for high temperature coating processes. In some coating processes that require high temperature environments, tantalum piping can remain stable without deformation or degradation of material properties due to high temperature. For example, in the high temperature coating in the aerospace field, tantalum capillary tubing can be used as a transport pipeline for high temperature gases or liquids to ensure the smooth progress of the coating process.

4. Prevent bath pollution and improve coating quality
Tantalum materials do not react with the plating solution during the plating process, which can prevent impurity pollution during the plating process, which is essential for the production of high-quality and high-precision coatings. Especially in the precious metal coating or ultra-thin coating process, the use of tantalum piping can significantly reduce the introduction of impurities and improve the surface quality and performance of the final product.

5. Core components for experimental equipment and coating equipment
Tantalum capillary tubes are also used in core equipment in the coating industry, such as electroplating machines, sensor elements in electroless plating equipment, gas or liquid flow control devices. The stable operation of these equipment cannot be separated from the corrosion resistance and high precision tantalum material, which can ensure the stability and durability of the equipment in long-term use.
