Castolin Trio is a leader in HVOF coating technologies, offering both OD and ID HVOF coating. We have two JP-8000 HVOF systems, one cHVOF (ID) and two HVOF cells. One cell benefits from a traverse machine setup for easy handling and set up of parts for coating, the other cell is equipped with a robot for coating complex geometries and inside coating. Our thermal spray coating services are supported by our large capacity of precision grinding and CNC machining. We are also equipped with an in-house lab for quality control of powders and new applications.

In contrast to welding, HVOF is a cold process where temperature of parts is kept below 150 °C, hence no thermal impact on the base material. HVOF is ideal for chrome plate replacement.

Typical coatings include high performance materials such as corrosion resistant metals, self-fluxing alloys and carbide blends. The various coatings can offer tremendous improvements in component performance such as wear, heat, oxidisation and corrosion resistance.

HVOF process is supported by the Castolin Eutectic global R&D team with Ph.D. specialists within HVOF. Castolin Eutectic is a manufacturer of powders for HVOF, and thus customized coating solutions can be developed.

HVOF characteristics:

• Temperature of part kept below 150 °C
• Adhesion strength ~ 69 Mpa
• <1% Porosity and low oxide
• Hardness values of up to 1400 Hv
• Surface roughness can be achieved down to 0,5 µm.
• International standards for testing are followed to ensure quality of coating
