Film production process of pvd vacuum coating equipment 


The film production process of pvd vacuum coating equipment is simply a process of transferring one material (film material) to the surface of another material (substrate) to form a film firmly bonded to the substrate. Therefore, any vacuum coating film production method includes three important links: source evaporation, migration and condensation.

Vacuum coating technology is a novel material synthesis and processing technology, and it is an important part of the field of surface engineering technology.


Vacuum coating technology is to use physical and chemical means to coat the solid surface with a layer of special performance coating, so that the solid surface has wear resistance, high temperature resistance, corrosion resistance, oxidation resistance, radiation protection, conductivity, magnetic conductivity, insulation and decoration And many other superior properties that are superior to the solid material itself, to achieve the effect of improving product quality, extending product life, saving energy and obtaining significant technical and economic benefits. Therefore, vacuum coating technology is hailed as one of the more promising and important technologies, and has shown attractive market prospects in the development of high-tech industrialization.


  It is mainly used for coating under high vacuum, and it is used in many industries, such as automotive, medical, transportation, machinery, service and other industries, and it is also a coating equipment that is very close to people's lives.


  Vacuum coating equipment is an important part of the coating industry. Without advanced and efficient coating machines, there would be no modern coating industry.


  Vacuum coating will encounter film drop. What is the reason for this situation and how to solve these problems?


  1, surface cleanliness

  The surface cleanliness of the product is not enough. Consider the argon amplification and longer time when cleaning the ion source.


  2, problems in the cleaning process

  The cleaning is not in place before plating, or the cleaning fluid is replaced.


   3. The problem of craftsmanship

   Whether there is any change in the process parameters, make appropriate adjustments in the coating time and current.


  4. The problem with the target material

   Whether the titanium target is poisoned, check and replace it.


   5. Whether the vacuum chamber is leaking

   Perform a leak detection.


  6, product surface oxidation

   There are many reasons for oxidation, so you can judge and deal with it yourself.
