Models and Options
The standard model is the HVOF Metal Surface Modification Treatment. Processing length can be specified from 0 to 30 m for steel workpieces. Coating design and process matching are customized to the component and its operating conditions.
Materials and Structure
The treatment is applied to steel substrates. During the HVOF process, a supersonic nozzle generates a high-speed flame to support coating preparation on the component surface. The coating system is selected through process matching and coating design so that the final surface modification meets the required hardness and bond strength targets.
Applications
This treatment is intended for hydraulic equipment components operating in extreme working conditions. It supports surface engineering requirements where high surface hardness, strong coating adhesion, and long workpiece processing are important for equipment reliability and service life.
