PVD Black Chrome Vacuum Coater for Golf Rods and Heads
Golf club vacuum coating machine is a device that uses magnetron sputtering or multi-arc ion technology to deposit thin films on the surface of the club in a vacuum environment. Its purpose is to improve the wear resistance, corrosion resistance, surface hardness and optical properties of the club, while meeting decorative needs.
Physical vapor deposition (PVD)
Principle: In a vacuum environment, the plating material is vaporized into atoms/molecules by heating or high-energy particle bombardment, or ionized into ions, which are directly deposited on the surface of the club.
Features: Fast deposition rate, low substrate temperature (usually below 100 °C), suitable for heat-sensitive materials (such as polymer composites).
Application: It is often used to prepare hard films (such as titanium nitride TiN, chromium nitride CrN) and decorative films (such as gold, black matte).
Process Control and Testing
Vacuum pressure control:
Pre-pump to ≤ 5 × 10⁻³Pa and maintain 1 × 10⁻¹-1 × 10⁻²Pa during deposition (depending on process and gas flow).
Power parameters:
The arc source current is 50-200 A (according to the target specification), and the substrate ion bombardment energy is controlled by pulse or DC bias.
Temperature monitoring:
The surface temperature of the substrate is monitored in real time, and the deviation of key batches is controlled within ± 5 ℃.
Film thickness measurement:
It is calibrated by white light interference or X-ray reflection (XRR), and is controlled online by polarized light thickness measurement or resistance monitoring in production.
Quality testing:
Salt spray test, abrasion test (grinding wheel or Taber), microhardness (nanoindentation), scratch adhesion test, gloss and color difference test (ΔE), etc.
