In the mid 1800's a scientist named Faraday evaporated thin films in a vacuum when he exploded wires in his laboratory. It was not until the late 1800's that the first films would be deposited in a vacuum by Nahrwold. This was the beginning of the vacuum deposition method that we now call PVD (Physical Vapor Deposition) coating.
Our Certess® DLC coatings are deposited using a PECVD system designed to produce dense high performance DLC coatings. NCT’s DLC coatings can be multi-layer or mono-layer depending on the application. Our PECVD system also has the capability to deposit sputtered films or layers as well utilizing our plasma enhanced magnetron sputtering (PEMS®) technology.
Plasma Nitriding, also referred to as ion nitriding, is a diffusion process that improves the wear resistance and fatigue properties of the product being nitrided. The process was developed in the 1920's as an alternative to the gas nitriding process. The plasma process is a thermal process performed in a vacuum environment.
Salt Bath Nitriding
The Melonite QPQ process is a multi step process that provides a very uniform consistent nitride layer on your components. The first step of the process is a preheat to raise the components surface temperature to about 700 - 800°F in air. The product is then transferred to the MEL 1/TF1 tank containing the liquid Melonite salt to begin the Nitrocarburizing process.
