PACVD Coatings
Plasma Assisted Chemical Vapor Deposition
Ionbond™ PACVD coating technology
PACVD coating technology is one of our coating technologies. The PACVD process is used for coating a very broad range of conductive and non-conductive substrate materials at temperatures below 200 °C. The typical thickness is in the range of 2 – 3 µm. The coatings are amorphous in structure and contain around 70% sp3 bondings, which accounts for the high hardness of the coating (10-40 GPa).
The ideal solution for tribological systems
DLC coatings feature excellent hardness, wear and low friction properties under dry or deficient lubrication conditions. They are ideally suited for tribological systems found in engines, machines and other mechanical assemblies with sliding and rolling movements. The perfect surface finish without any post-treatment makes them ideal for high precision injection molding tools as well as for decorative purposes such as watches and sanitary. DLC is chemically inert and biocompatible which allows for its application on medical components and implants.
Broad range of substrate materials
No distortion of high precision substrates
No post treatment necessary
Gaseous process for uniform coating of 3D geometries without rotation
Green technology with respect to educts, process and products
What is Plasma Assisted Chemical Vapor Deposition (PACVD)?
PACVD (Plasma Assisted Chemical Vapor Deposition) is a vacuum based process used to deposit DLC (Diamond Like Carbon) coatings, also known as ADLC (Amorphous Diamond-Like Carbon). All educts of the PACVD process are gaseous. This makes it suitable for coating 3D components uniformly, without the need for rotation as is necessary in PVD coating technologies.
PACVD is also known in the market as Plasma Activated Chemical Vapour Deposition and Plasma Enhanced CVD.
Frequently asked questions on PACVD coating services
Prior to coating, substrates (tools and components) must be free of foreign substances, oils, or grease on all surfaces, not only those to be coated. Proper cleaning is critical for optimal adhesion and maximum CVD coating performance. Ionbond’s process includes a thorough cleaning phase, and we encourage clients to discuss the ideal preparation for their specific substrates.
Masking is generally easy with PVD, a line-of-sight process, while masking for PACVD is more challenging, and for CVD it is quite difficult. Contact us to discuss masking options for PVD and CVD coatings.
Typical lead times for both PVD and CVD coating services are usually 3 to 5 days. Test parts and sampling may take additional time for fixturing and process design.
