What isPVDcoating on stainless steel

Alibaba.com is a marketplace that provides high-quality concave grinding wheel sourced from some of the top manufacturers respected in the industry.

PVD coatings can be applied on components using different methods such as arc evaporation, magnetron sputtering to name a few. HEF specializes in plasma enhanced magnetron sputtering, CAM (coating assisted by microwaves) and modified arc evaporation coating technologies.

CERTESS® NITRO is a tradename of HEF Group for Nitrogen based PVD coatings. Depending on your application, there are different options that can be provided within the family of CERTESS® NITRO coatings. Some of these include:

PVDcoating vs electroplating

When tools and dies remain in operation without replacement due to wear, our customers realize less machine downtime, operator idle time, and expense of new or resharpened tools and dies. The end result is far greater productivity and lower costs.

We know your frustration when wear causes costly downtime, you get slip instead of grip, or you’re stuck replacing expensive equipment that should have lasted longer. We believe there’s a better way. That’s why we developed The Rocklinizer - the portable and affordable hard surfacing solution that’s proven to deliver real cost savings, quickly.

PVD coatings involve the deposition of thin (2-10 microns; 0.0001" – 0.0004") films on the surface of tools and components.

In general, PVD coatings are thin film and are in the range of 1 to 5 microns. For reference, 25 microns equals 0.001 inches. Red blood cells are around 8 microns in diameter, while human hair is around 80 microns in diameter. Thus, PVD coatings are extremely thin-film coatings with thickness specification defined within this 1 to 5-micron range depending on the application requirement.

PVDcoating full form

Liquid nitriding is a subcritical surface enhancement process with one of the longest track records of success of any case hardening technology.

The Rocklinizer electronically impregnates extremely hard and wear-resistant material onto metals, tools, and dies using our proven spark deposition process. Unlike welding or metal spraying, no appreciable heat is generated; and the electrode material will not separate or flake off the workpiece. After using the patented Rocklinizing process, no heat treatment, grinding or other surface treatment is necessary.

What isPVDcoating used for

PVD coatings have a hardness value around 1500 – 4500 HV (Vickers) depending on the type of coating offered. Vickers (HV) is a microhardness unit for measuring thin film coatings. For reference, 900 HV corresponds to 67 HRC (Rockwell C) hardness. Generally, carbon steels have a hardness range around 250 HV (25 HRC), nitrided or nickel and chrome plated steels fall in the range of 600 HV to 1000 HV surface hardness. Thus, PVD coatings are extremely hard and hence, very durable and wear resistant.

PVD coating is carried out in a vacuum chamber at an extremely low-pressure range (typically 10-3 to 10-9 Torr. Standard atmospheric pressure is 760 Torr) where in the component to be coated is placed in front of a high purity target source in a plasma environment (ionized gas). A target is the primary material source used for the coating (for example: Titanium for Titanium Nitride, Chromium for Chromium Nitride, etc.) This process involves three critical steps:

Yes. There are different types of PVD coatings that can be offered depending on the application requirements. Titanium Nitride (TiN), Chromium Nitride (CrN), Titanium Aluminum Nitride (TiAlN), Titanium Boron Nitride (TiBN) are some examples of PVD coatings.

HEF bushings are recognized worldwide for their excellent frictional and anti-seizure properties, and ability to withstand high loads.
