Physical Vapor Deposition (PVD)

Physical Vapor Deposition (PVD) is a process of creating a thin film with high hardness. This film has low surface friction, excellent abrasion resistance, able to resist oxidation and corrosion resistance which helps to prolong product lifespan.

Physical Vapor Deposition (PVD)

When a part start working, the first point that will begins to wear is its surface. Therefore, increasing surface strength will help to reduce wear, resulting in extended its service life.

If we make the surface more slippery, it can reduce friction and reduce energy required to drive the part as well.

PVD coating technology is a physical coating under vacuum conditions to obtain a micron thin film on metal surface. The hardness of coated film is higher than Tungsten carbide.

When compared to Hard chrome or Nitriding, PVD-coated films have higher hardness, can greatly reduce wear with a few microns of thin films and there is no worry about the diameter changed.

Moreover, the strength of hardened steel that heat treatment at high temperatures such as SKH, SKD will not change because PVD coating temperature control at lower than 500°C which is not the temperature range of changing steel structure.
