State-of-the-Art PVD Coating Engineering


State-of-the-Art PVD Coating Engineering

The next generation of engineered material PVD coating treatments is now available from SurfTech. Our physical vapor deposition (PVD) coatings are available on all types of electrically conducting materials and surfaces including all traditional tool and wear component substrates.

Plus, for the first time!

All electrically non-conducting materials can be PVD coated including:

· composites,
· cermet,
· silicon nitride,
· black ceramic,
· silicon carbide,
· pure alumina,
· PCD and
· CBN.

SurfTech’s surface coatings are nano-structured, multi-material, high-density films and they are deposited well below 200°F/93.3°C.

Nanotechnology: The Secret to Low-Temperature PVD Coatings

These achievements are routine to us. They are made possible by combining two patented cutting-edge technologies:

1. Ion Activation Devices (IAD), and

2. Nanostructured Material Synthesis (NMS)

The SurfTech IAD processing involves proprietary and patented plasma-based devices.

The NMS technology is based on coatings developed over the past 20 years to make state-of-the-art x-ray mirrors and aerospace quality, space-qualified patented solid film lubricating films.

Together, IAD and NMS enable hard, lubricious, smooth, pour-free vacuum deposited coatings at temperatures below all known annealing temperatures. There is no change of material hardness or toughness—no matter whether the substrate is bearing steel, PCD, CBN, previously coated tools, brazed carbide, carbides, ceramics or high strength composites.

Coatings are deposited with mean thicknesses from less than 40 micro-inches to greater than 100 micro-inches (1 -3 microns) with +/-5% tolerance which allows us to perfectly replicate the surfaces of components being coated. Corners remain sharp and surface finish is maintained with no distortion.

All these features are obtained without using any heating of the components or any form of electrical bias before, during or after the treatment process.

Substrates Stay in Tact with SurfTech PVD Coating Process

Because SurfTech controls the plasma beam particle energies and number independently, we can put the necessary thermal and chemical energy into the surface treatment process, not into heating the chamber and the bulk mass of the components. SurfTech uses less energy to get this job done and can perform this work on large, small, flat, or round components—in the same batch—without exceeding 180°F. This makes SurfTech processing a significant cost advantage for you.

This unprecedented degree of control results in:

· No annealing of the substrate
· No softening of the substrate
· No warping,
· No bending
· No twisting

Nothing happens in our PVD coating process to affect the dimensions of your component.

Since the nanostructured treatment is built with individual atomic layers at a time, SurfTech has a higher degree of control over treatment thickness resulting in tighter tolerance. SurfTech treatments perfectly conform to the component’s surface because of the controlled use of plasma beams to precisely conform the nanostructures to the surface topography without changing the fine sharp cutting edges on tools or other intricate details designed into the components surfaces. SurfTech treatments keep mirror-like finishes mirror smooth. Our surface treatments preserve our your designs and reflect our respect for your engineering skills by enhancing, not changing.
