Introduction: When the Heat Is On, Performance Matters

In the blazing heart of an engine, a furnace, or a turbine — one thing decides whether operations continue smoothly or come to a costly halt: heat resistance.
Industrial components face relentless temperatures that would melt, crack, or oxidize most materials. That’s where heat-resistant coatings step in — the unsung heroes that keep industries running efficiently, safely, and profitably.

At DOMADIA™, we engineer coatings designed not just to survive the heat but to thrive in it. From aerospace turbines to steel plants, our advanced coatings form the invisible armor that protects, preserves, and performs.

Understanding Heat-Resistant Coatings

Heat-resistant coatings are engineered surface layers that can withstand extreme thermal exposure — often exceeding 600°C to 1200°C — without losing structural integrity or protective properties. These coatings protect metals and alloys from:

✅ Oxidation
✅ Corrosion
✅ Thermal fatigue
✅ Scaling and surface degradation

By forming a stable barrier against oxygen, moisture, and heat, they extend component life, reduce downtime, and minimize maintenance costs.

Chemical Composition

Depending on the industrial use, heat-resistant coatings come in several formulations:

  1. Ceramic-Based Coatings (Al₂O₃, ZrO₂, SiO₂):
    Excellent for ultra-high temperatures and insulation. Used in aerospace and defense applications.
  2. Metallic Coatings (NiCr, AlSi, ZnAl):
    Provide oxidation resistance and thermal protection for turbines, exhausts, and engine parts.
  3. Silicone-Resin-Based Coatings:
    Common in automotive and industrial exhaust systems for continuous exposure to 600°C.
  4. Thermal Barrier Coatings (TBCs):
    Typically multilayered — a metallic bond coat with a ceramic topcoat — offering both adhesion and insulation.

Applications Across Industries

  1. Aerospace & Defense:
    Turbine blades, combustion chambers, rocket nozzles — every component demands superior thermal control.
  2. Automotive & Powertrain:
    Used on exhaust manifolds, pistons, and turbochargers for improved performance and fuel efficiency.
  3. Metallurgy & Foundries:
    Protects furnaces, molds, and ladles from thermal erosion.
  4. Petrochemical Plants:
    Used in reactors, pipelines, and heat exchangers to handle high-temperature chemical reactions.
  5. Energy Sector:
    Essential in boilers, turbines, and solar thermal systems to maintain energy efficiency.
