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 increase efficiency. Costs are reduced due to longer-lasting tools and increased cutting speeds and feeds, which results in higher productivity. PVD coated tools can be run with dry or with minimum lubrication (or release agents in the case of forming tools) saving both operating and recycling costs. PVD coatings on mechanicals reduce friction and wear and improve 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 is a line of sight process which requires substrates to be rotated in the chamber (from single to triple rotation) in order to achieve the required homogeneous coverage and thickness. Coating of inner diameters in PVD is restricted to a depth equal to the diameter of the opening.
The CVD 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 of our CVD coating services usually fall within the range of 3 to 5 days. Test parts and samplings take more time as fixturing and process design is required.

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.
