What Is Thermal Spray Coating?
Thermal spray coating is a surface engineering process in which metallic, carbide, ceramic, or alloy materials are heated or melted and propelled onto a prepared component surface. The particles impact the substrate and form a protective coating layer.
The purpose of thermal spray coating is to improve specific surface properties without necessarily replacing the complete component. Depending on the application, coatings can provide improved resistance to:
- Abrasion
- Wear
- Erosion
- Corrosion
- Oxidation
- Friction
- High-temperature degradation
When evaluating Thermal Spray Coating Companies in India, industries should consider technical expertise, coating technology, material selection, surface preparation, finishing capabilities, quality control, and experience with similar industrial applications.
Why Are Thermal Spray Coating Companies Important for Indian Industries?
Thermal Spray Coating Companies in India India has a large and diverse industrial sector comprising power generation, steel, cement, oil & gas, mining, chemicals, engineering, manufacturing, and process industries. Machinery in these sectors often operates continuously under severe service conditions.
A professionally applied thermal spray coating can help protect critical surfaces and potentially extend component operating life.
The major benefits include:
- Improved wear resistance
- Better abrasion protection
- Enhanced erosion resistance
- Corrosion protection
- Increased component durability
- Reduced maintenance frequency
- Lower component replacement costs
- Reduced equipment downtime
- Restoration of selected worn components
- Improved lifecycle cost management
However, the effectiveness of a coating depends on selecting the correct coating material and technology for the actual operating environment.
Types of Thermal Spray Coating Technologies
Leading Thermal Spray Coating Companies in India may offer different technologies depending on the application.
HVOF Coating
High Velocity Oxy-Fuel (HVOF) is an advanced thermal spray technology used for demanding wear, abrasion, erosion, and corrosion applications.
ATSPL applies tungsten carbide and chromium carbide coatings to components including valves, shafts, rollers, pump components, turbine parts, compressor parts, and other industrial wear surfaces. The company’s published HVOF specifications include micro-hardness up to 1400 HV, bond strength exceeding 10,000 PSI, and porosity below 1% for applicable coating systems.

Steel Industry
Steel manufacturing involves high temperatures, mechanical loads, abrasion, and continuous operation. Thermal spray coatings can be applied to suitable rollers, shafts, guides, and other components to improve surface durability.
Cement Industry
Cement production creates highly abrasive operating environments. Suitable wear-resistant coatings can help protect components exposed to abrasive materials and particles.
Oil & Gas
Oil and gas equipment may face corrosion, erosion, friction, and demanding mechanical conditions. Application-specific thermal spray coatings can provide additional surface protection for suitable components.
Mining
Mining equipment is exposed to severe abrasion and impact. Wear-resistant coatings can help protect selected components and potentially reduce premature surface deterioration.
Chemical and Process Industries
Chemical processing equipment may operate in corrosive and high-temperature environments. Selecting an appropriate coating system can improve surface protection for suitable components.
Component Restoration and Reclamation
One important capability offered by specialized Thermal Spray Coating Companies in India is component restoration.
Industrial components can lose material because of wear, corrosion, or repeated operation. In suitable cases, thermal spray technology can be used to rebuild the worn surface, followed by grinding or finishing to achieve the required dimensions.
ATSPL provides Roller & Cylinder Reclamation and Component Restoration & Specialty Coatings as part of its surface engineering services.
