Thermal Spray

What Is Thermal Spray?

Thermal spray is a method that sprays a surface (usually metal) with a material to make it stronger, more wear-resistant, rust-proof, heat-insulating, or electrically conductive.

What Are the Steps Included in the Thermal Spray Process?

Nowadays thermal spray coatings are widely used in various industries such as aerospace, automotive, oil & gas, power generation, medical devices, marine, electronics, manufacturing, steel and mining and more. Here are some steps in the thermal spray process is as follows:

• Surface Preparation: To guarantee coating adhesion, clean and roughen the surface (typically with abrasive blasting).
• Material Selection: Depending on the application, select the right coating material (alloy, metal, or ceramic).
• Heating the Material: Melt or soften the coating material by heating it with a thermal spray technique (arc, flame, plasma, or HVOF).
• Spraying: To apply the molten substance to the prepared surface, use compressed air or high-speed gas.
• Coating Build-Up: Apply several coats to increase the coating’s desired thickness.
• Post-Treatment (Optional): Depending on the application, complete with sealing, polishing, or grinding.

Types of Thermal Spray Coating Methods

• Arc Spray:
• Flame Spray:It uses a fuel gas and oxygen flame to melt coating material, which is subsequently atomized and sprayed to surfaces, making it suitable for automotive and wear-resistant coating applications.
• Plasma Spray:It creates a high-temperature plasma jet to melt and accelerate coating powders, resulting in dense and durable coatings suited for aerospace and industrial applications.
• High-Velocity Oxy-Fuel (HVOF):This burns oxygen and fuel gas to produce a high-speed flame that melts and propels coating material, offering coatings with exceptional hardness and wear resistance for aerospace and industrial uses.

Benefits of Thermal Spraying

• Thermal spraying protects surfaces from wear, rust, and heat, making parts last longer.
• It reduces the need for frequent repairs or replacements and saves money.
• Thermal spray coatings work on many metals, ceramics, and plastics.
• By using quality thermal spray coatings we can improve surface strength, reduce friction, and increase resistance to heat and electricity.
• You can choose the right coating thickness and material for your needs.
• Thermal spray coating is environmentally friendly as it uses less material and reduces material waste.
