Coating is a technique of applying one or more thin films on the surface of materials, which can be made of metals, alloys, ceramics, plastics, or composite materials. The main purpose of coating is to provide protection, increase hardness, improve appearance, provide conductivity or other functionality.

When choosing coating technology, the following factors are crucial:

Application requirements: Clearly define the functional and performance requirements of the required film.

Substrate characteristics: Consider the influence of substrate material, surface condition, etc. on coating effect.

Cost effectiveness: Evaluate the cost and expected benefits of the coating process, and choose a cost-effective solution.

Technological maturity: Choose coating processes and equipment with mature technology and high reliability.

Coating technology, seemingly insignificant, plays a huge role in various fields. It is not only a breakthrough in materials science, but also a key driving force for the development of modern technology.
