All Services
High-Temperature, Oxidation-Resistant Ceramic Coating Solutions
Metallic ceramic coatings, commonly known by SermeTel trade names, are engineered to protect metal substrates exposed to heat, corrosive environments, and abrasive conditions. These coatings form a dense, chemically resistant barrier that enhances part life, prevents oxidation, and supports performance in high-temperature applications.
Capability & Coating Highlights
- SermeTel metallic ceramic coating systems
- Oxidation- and corrosion-resistant formulations
- High-temperature stability
- Excellent adhesion and uniform coverage
- Chemical and solvent resistance
- Ideal underlayers for additional coating systems
- Applied to spec for aerospace and industrial environments
How Metallic Ceramic (SermeTel) Coatings Work
Step 1 — Surface Preparation
Proper adhesion and performance begin with controlled substrate preparation, which may include:
- Abrasive blast cleaning
- Chemical pretreatment
- Precision masking for complex geometries
This ensures the ceramic coating bonds consistently to the base metal.
Step 2 — Coating Application
Metallic ceramic coatings are applied as uniform layers containing aluminum or other metallic particles in a ceramic binder. These coatings:
- Prevent oxidation at elevated temperatures
- Provide barrier protection from corrosive environments
- Maintain integrity under mechanical stress
Step 3 — Controlled Curing Cycle
Heat curing allows the ceramic matrix to chemically bond to the substrate, creating:
- A dense, tightly adhered coating
- Long-term stability under repeated thermal cycling
- Enhanced corrosion and oxidation resistance
Step 4 — Inspection & Verification
MIL performs detailed inspection for:
- Coverage uniformity
- Adhesion
- Surface integrity
- Thickness measurements (as required)
- Spec documentation and final validation
Why Work With MIL for Metallic Ceramic Coatings?
Proven Experience With SermeTel and Metallic Ceramic Systems
MIL has decades of experience interpreting aerospace and defense coating specifications for metallic ceramic systems, including SermeTel formulations.
Reliable Performance in High-Temperature Environments
Metallic ceramic coatings are used when oxidation, corrosion, or extreme thermal exposure must be controlled. MIL ensures coatings meet or exceed performance expectations.
Integrated Processing for Complex Applications
Parts often require multiple processes such as NDT, masking, anodize, or painting – in addition to ceramic coatings. MIL reduces handling and lead time by performing these services in one facility.
