The hard film PVD coating machine is a key equipment that uses physical vapor deposition technology to deposit hard materials in atomic or molecular state onto the surface of the workpiece under a vacuum environment to form a film with excellent performance such as high hardness, high wear resistance, high corrosion resistance, and low friction coefficient.

Advantages of Our Coating Machine

1. Proprietary low‑temperature ion‑assisted cold‑coating technology: Dedicated ion‑assisted source enables coating without high‑temperature baking for many workpieces. Expands compatibility for heat‑sensitive substrates, reduces energy consumption and improves production capacity.

2. Hybrid multi‑arc‑magnetron deposition: One single chamber supports both multi‑arc ion plating and magnetron sputtering. Delivers high‑adhesion hard tool coatings as well as complex multilayer composite films for multi‑purpose production.

3. Strong customisation capability: Chamber dimension, target quantity and fixture rotation mechanism can be tailor‑made, including large‑size sheet / tube functional coating equipment.

Applications:

Functional film coating on the surface of various medical devices

Surgical instruments (scalpels, scissors, orthopedic instruments), dental drills/instruments, implants (artificial joints, bone screws, cardiovascular stents), etc.

Function: Improve the sharpness and durability of the instrument edge and reduce wear; give the implant surface excellent wear resistance, corrosion resistance, biocompatibility (such as DLC, TiN, ZrN), and sometimes antibacterial properties (such as Ag-containing film layer).

Excellent film performance:

High hardness: The formed film layer has extremely high hardness, far exceeding that of the base material, which significantly improves wear resistance.

Good wear resistance: Greatly reduce friction and wear, and extend the service life of the workpiece.

Strong corrosion resistance: Many hard film layers, good chemical stability, can effectively isolate the substrate from the corrosive environment.

Low coefficient of friction: Some films are self-lubricating, which reduces friction and adhesive wear.

Good bonding strength: Through reasonable process control (such as ion cleaning, transition layer), the film layer is firmly bonded to the substrate.

Good thermal stability: Many hard coating layers can maintain their hardness and performance at high temperatures.

Aesthetics: Different film layers present different colors and have both decorative effects.
