Pvd coating machine coating technology process steps and principles
In terms of ion plating, the evaporated material particles have a kinetic energy of 3000~5000 electron volts after ionization. High-speed bombardment of the workpiece not only accelerates the deposition speed, but the PVD coating machine can also penetrate the workpiece surface, injecting into the substrate to form a very deep diffusion layer. The interface diffusion depth of ion plating can reach 4~5 micrometers.

Introduction to the coating principle of PVD coating machine
The coated workpiece of the PVD coating machine is processed in a vacuum chamber. Physical vapor deposition (PVD) coating technology is mainly divided into three categories: vacuum evaporation coating, vacuum sputtering coating, and vacuum ion coating. The vacuum coating machines corresponding to the three classifications of PVD coating machine technology include vacuum evaporation coating machines, vacuum sputtering coating machines, and vacuum ion plating machines. In recent decades, vacuum ion plating technology has developed rapidly and has become one of the most advanced surface treatment methods today. The PVD coating we often talk about refers to vacuum ion coating. Let's learn about the PVD coating machine coating principle!

What are the steps in the PVD coating process?
Before the PVD coating process, the machine requires color removal, spraying, polishing, passivation, cleaning, and clamping. Coating process, vacuum extraction, heating and baking, leak testing, bombardment cleaning, coating, and post-cooling process: First, the cleaning process ensures the cleanliness of the product surface before PVD coating. The fresher the surface, the better the coating quality.

PVD coating machine manufacturer tells you maintenance secrets
When using a PVD coating machine, after completing more than 200 coating processes, the equipment must be cleaned with a saturated sodium hydroxide (NaOH) solution. The inner walls of the vacuum chamber should be repeatedly scrubbed with a saturated sodium hydroxide (NaOH) solution. (Note: Human skin should not come into direct contact with caustic soda solution to avoid burns.) The purpose is to allow the coated aluminum (Al) to react with NaOH. After the reaction, the film will peel off and release hydrogen gas.

Several coating methods for PVD coating machines
Vacuum coating technology, simply put, uses methods such as evaporation and sputtering to emit coating particles, which are deposited on objects such as metals, glass, ceramics, semiconductors, and plastic parts to form a coating. The main methods of PVD coating machines include the following:

The working principle of PVD coating machine
The working principle of the PVD coating machine is to utilize low-pressure, high-current arc discharge technology to vaporize and ionize the target material under vacuum conditions. Under the action of an electric field, the PVD coating machine deposits the evaporated substance or its reaction products onto the workpiece. The thickness of the PVD coating machine film layer is on the micron level, relatively thin, so we can continuously improve it without affecting the original different Sizes of the workpiece almost simultaneously.

The technological principle and application of PVD coating machine
PVD coating machines utilize a surface treatment technology that involves sputtering, evaporation, or ion plating of materials such as titanium, gold, graphite, crystals, and other metals, non-metals, or gases onto substrates under vacuum conditions. Compared to traditional chemical coating methods, vacuum coating offers several advantages: it is environmentally friendly and a green process; it is harmless to operators; and the coating is strong, dense, highly corrosion-resistant, and uniform in thickness. Commonly used methods in PVD coating machine technology include evaporation coating (including arc evaporation, electron beam evaporation, resistance wire evaporation, etc.) and sputtering coating (including DC magnetron sputtering, medium-frequency magnetron sputtering, radio frequency sputtering, etc.), which are collectively referred to as...

How to measure the film thickness of a PVD coating machine?
In our daily lives, many household products are coated with a film using a PVD coating machine, making the products not only more aesthetically pleasing but also more practical. However, many people have a question: since the film is coated, it must have a certain thickness. So, how thick is the film, and how can it be measured? Below is a detailed introduction on how to measure the film thickness after PVD coating, hoping it will be helpful to you:
