HVOF thermal spraying (High Velocity Oxy-Fuel spraying)

HVOF thermal spraying (High Velocity Oxy-Fuel spraying)

High-speed jet frame spraying using oxygen and fuel.

◆◇◆ What is HVOF Thermal Spraying ◆◇◆ It stands for High Velocity Oxygen Fuel. It refers to thermal spraying using a high-speed jet flame created by oxygen and fuel. A mixture of high-pressure oxygen and fuel gas is burned in a combustion chamber. The combustion flame is constricted by a nozzle, and the moment it exits into the atmosphere, a rapid gas expansion occurs, resulting in a supersonic jet. The thermal spray material accelerated by high kinetic energy forms a high-density coating with minimal oxidation or compositional changes.

HVOF thermal spraying (High Velocity Oxygen Fuel spraying)

HVOF thermal spraying (High Velocity Oxygen Fuel spraying)

It is a super hard coating technology that possesses a dense film characteristic with strong adhesion to the substrate, resulting in extremely high wear resistance and corrosion resistance.

"HVOF thermal spraying (High Velocity Oxygen Fuel spraying)" is a super hard thermal spray coating adapted for wear and corrosion resistance. Due to the smooth surface of the coating, it is easy to achieve a super mirror finish, and a thick film formation is also realized. The extremely high particle velocity (500–800 m/s) produces a coating with very high density and low porosity. Additionally, because the material is fed at ultra-high speed, the time it is exposed to the flame is minimized, allowing for the reduction of oxidation and alteration to a minimum. 【Features】 ■ High density ■ High adhesion ■ Oxidation and alteration suppression ■ Surface smoothness *For more details, please refer to the PDF document or feel free to contact us.

Thermal Spray Processing Terminology Glossary【1】

Thermal Spray Processing Terminology Glossary【1】

Thermal Spraying Processing Glossary

● What is thermal spraying? Thermal spraying is a type of surface modification method that uses heat sources such as fuel-oxygen combustion and electrical energy to heat spraying materials, creating particles in a molten or near-molten state that are then sprayed onto a substrate to form a coating. Thermal spraying has many advantages compared to other surface modification methods (such as surface hardening, carburizing, nitriding, ion implantation, plating, vapor deposition, and build-up welding). ● What is gas thermal spraying? A general term for thermal spraying conducted using a combustion flame of oxygen and combustible gas. ● What is flame spraying? A process that uses a combustion flame of oxygen and combustible gas to heat and melt linear, powder, or rod-shaped thermal spraying materials, which are then sprayed onto a substrate to form a coating. Flame spraying includes wire flame spraying, powder flame spraying (self-fusing alloy spraying), high-velocity flame spraying (HVOF spraying), and rod flame spraying (low-cast spraying). ● Wire flame spraying Uses linear thermal spraying materials. ● Powder flame spraying (self-fusing alloy spraying) Uses powder thermal spraying materials. ● Rod flame spraying (low-cast spraying) Uses rod-shaped thermal spraying materials. ● High-velocity flame spraying (HVOF spraying) Ultra-high-speed thermal spraying that uses gas flame as the heat source.
