Thermal Spray Coating for Mechanical Components

Home Mechanical Components

Heavy-Duty Industrial Components Protected with Wear- and Corrosion-Resistant Coatings

Gears, bearings, and couplings are all mechanical parts that experience constant friction, abrasion, and chemical exposures in high industrial equipment. Get a hard, corrosion-resistant coating of our thermal spray that improves the performance of a surface and lowers the wear of the material.

Precision Thermal Spray Solutions Extending Lifespan and Enhancing Machinery Reliability

The coatings enhance load carrying, rotary smoothness, and thermal stability of components, such that they are in a position to withstand the harsh conditions of functioning. The maintenance of the industries that use coated mechanical parts is predictable and cost-effective as these industries experience longer equipment life, less downtime, and even better productivity.

Key Advantages for Mechanical Components

Dimensional Reclaiming: Rebuilds worn metal shafts, bearing journals, and seals back to their original design tolerances.

Excellent Hardfacing: Deposits alloys with hardness exceeding 65 HRC to prevent sliding friction and contact wear.

Saves Repair Costs: Restoring old machine components is up to 70% cheaper than procuring new OEM replacement parts.

Broad Material Compatibility: Can deposit stainless steel, bronze, carbides, and ceramics onto steel, copper, or cast iron bases.

Custom Surface Solutions for Diverse Mechanical Components

Industrial machinery consists of numerous mechanical components—such as gears, cams, guides, spindles, and sleeves—that experience high stress, friction, and wear. Standard metals often lack the surface properties required to survive in harsh operating environments. Our thermal spray coatings allow engineers to select cost-effective base metals for structural strength while customizing the surface properties for wear and corrosion resistance.

Whether using HVOF, Flame Spray, or Twin Wire Arc Spray, we apply a wide variety of coatings including tungsten carbides, nickel-chrome alloys, and ceramics. These coatings are engineered to fit specific component geometries and working conditions, protecting them against sliding friction, fretting, and abrasive wear, thereby extending machinery life and reducing maintenance costs.

Key Features & Technical Capabilities

Fretting and Wear Protection: Prevents micro-motion wear in tightly fitted mechanical interfaces.

Enhanced Load Carrying Capacity: Hard surfaces withstand high localized pressures without deformation.

Corrosion and Rust Prevention: Protects moving mechanical linkages from moisture and chemicals.

Component Cost Savings: Upgrades standard steel components with premium surface properties.

FAQs for Mechanical Component Coatings

1. Which mechanical components can be coated? +

Shafts, rotors, bearing journals, seals, housing bores, gears, coupling areas, and sliders can be coated.

2. Can thermal spray restore worn-out industrial parts to original dimensions? +

Yes. Thermal spray allows build-up of metal/carbide layers that are machined down to the exact original sizing.

3. What are the benefits of hardfacing mechanical components? +

It improves sliding wear resistance, lowers friction, protects against galling, and increases oil retention in mechanical machinery.

4. How does thermal spray compare to hard chrome plating? +

Thermal spray (like HVOF Tungsten Carbide) is harder, thicker, has higher bond strength, and is an eco-friendly replacement for hexavalent chrome plating.

5. What materials can be sprayed on mechanical parts? +

We apply cobalt alloys, nickel alloys, stainless steel, chrome oxide ceramics, and tungsten carbide overlays depending on the application.

6. Do you provide a warranty for mechanical component reclamation? +

Yes. All our mechanical component reclamation projects come with a quality warranty covering the bond strength and dimensional tolerances under standard operating conditions.
