Hard Film PVD Coating Machine

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.

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).

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.
