Small PVD coating machines can be primarily categorized into the following types based on their technical principles and application scenarios:

1. Resistance Heating Evaporation Coating Machine:

Principle: A resistance wire heats the evaporation source, causing it to vaporize and then deposit onto the substrate surface.

Features: Low cost, suitable for low-melting-point materials; simple process, fast deposition rate, and high-purity film; however, they suffer from weak adhesion, poor wraparound performance, and low coverage on complex workpieces.

2. Electron Beam Evaporation Coating Machine:

Principle: Electron beams bombard a high-melting-point target, achieving evaporation temperatures exceeding 3000°C.

Features: Capable of depositing high-melting-point materials and producing high-purity films; however, equipment costs are high and process control is complex.

3. DC Magnetron Sputtering Coating Machine:

Principle: Under vacuum conditions, a DC electric field is used to bombard the target with argon ions, causing target atoms to sputter and deposit onto the substrate surface.

Features: Dense films with strong adhesion are suitable for complex workpieces; a wide range of materials can be deposited; however, equipment costs are high and target utilization is low.

4. RF Sputtering Coating Machine:

Principle: A non-conductive target is bombarded by an RF electric field, generating gaseous particles that are deposited on the substrate.

Features: Can deposit insulating materials; however, the deposition rate is relatively low.

5. Multi-Arc Ion Coating Machine:

Principle: Utilizes an arc to evaporate the target, resulting in high ion energy and a fast deposition rate.

Features: Excellent film adhesion, capable of producing ultra-hard, wear-resistant coatings; excellent wraparound performance; however, the process control is complex and prone to droplet contamination.

6. Hot Cathode Ion Coating Machine:

Principle: Suitable for high-melting-point materials, with excellent film uniformity.

Features: High film quality, but high equipment cost and complex process control.
