Post-Spray Capabilities

Post Spray Coating Processing

Thermal Spray Technologies performs post-spray operations including sealing, grinding, lapping, super finishing, and heat treating.

Grinding and Lapping

We are capable of production grinding and lapping planar surfaces to a flatness of one helium light band and a roughness of one micro-inch RA. Our capability includes parts up to 10.5 inches (267 mm) in diameter. Larger parts can also be finished using TST’s extensive vendor base.

Grinding and Superfinishing

We grind cylindrical surfaces to a roughness of 16 RA and super finish to 2-3 micro-inches RA. We can finish cylinders and rolls up to 12 inches (305 mm) diameter, 100 inches (2.54 m) in length, and 1,000 pounds (454 kg). Larger parts can also be processed using outside vendors.

Sealers

Coating sealers are applied to enhance corrosion resistance, dielectric properties, non-stick, etc. Sealers range from room temperature to elevated temperature curing for more severe applications.

Heat Treatments

TST performs a variety of post coating heat treatments to enhance coating properties such as creating strong metallurgical bonding, coating densification, reducing oxides, and improving corrosion resistance. Our materials engineering staff will develop a customized heat treatment for your coated component to maximize the components performance.
