Our coating technologies
PVD coating
PVD is a method for producing metal-based hard coatings by means of generation of partially ionized metal vapor, its reaction with certain gases and by forming a thin film with a specified composition on the substrate.
CVD coating
Chemical Vapor Deposition is a method for producing low stress coatings by means of thermally-induced chemical reactions.
CVA coating
Chemical Vapor Aluminizing is based on the CVD process and is used for the production of diffusion aluminide coatings for high temperature applications.
PACVD coating
PACVD is a vacuum based process used to deposit DLC coatings, also known as ADLC.
DLC coating
Diamond-Like Carbon coatings can be deposited by different technologies such as PVD arc, PVD sputtering and PACVD processes.
Laser Hardening
Reduce coefficient of friction and gain higher throughput, reproducibility and product quality.

Frequently asked questions
PVD coatings reduce long-term costs and improve efficiency by enabling longer-lasting tools and allowing for increased cutting speeds and feeds, thus boosting productivity. PVD-coated tools can run dry or with minimal lubrication (or release agents for forming tools), saving on both operational and recycling costs. In mechanical components, PVD plating reduces friction and wear, enhancing performance and reliability.
Prior to coating, substrates (components) need to be free of any foreign matter, oils and grease on the surfaces that are to be coated, but also in all other areas. The cleaning process is an essential element that determines the adhesion and thus influences the performance of the coated part. All parts are cleaned by Ionbond prior to coating, using a designated process. Ionbond encourages customers to discuss the optimum requirements for their substrates in order to ensure top performance.
Ionbond coating processes will typically add a few µm of thickness to the components and tools. Coatings generally conform to the surface condition of the tool and do not act as fillers or levelers. Depending on the process, a small amount of roughness may be added. In such cases where extremely smooth surface finishes are required, post coating polishing can be carried out if required by the customer.
The PVD coating process operates on a line-of-sight basis, requiring substrates to rotate in the chamber (from single to triple rotation) to achieve consistent coverage and thickness. Coating inner diameters is restricted to a depth equal to the diameter of the opening.
The CVD coating processes produce uniform and homogeneous coatings on the outside and the inside of the part or tool, which rests static in the chamber.
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.
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.
CVA coatings reduce long term costs and increase efficiency. Costs are reduced due to longer-lasting components, which results in higher productivity. CVA is an environmentally friendly proces which results in not generating waste powders. CVA coatings furthermore offer remarkable resistance to high temperature oxidation and corrosion.
