Silicon Carbide Post-Processing

We have the ability to chemically deposit high purity Silicon Carbide onto large surfaces and parts or even infiltrate porous materials. We use chemical vapor infiltration to fill in the gaps and achieve a sealed layer on the outside of a part. Our automated production cycle is one of the largest chemical infiltration systems ever made and can produce parts that are 20 inches in diameter.

Parts are loaded on a multi-level crucible that is inserted into the reaction chamber. Gas is flowed at high temperatures to deposit reaction products onto the ceramic surfaces. After several days of deposition, the densification or coating is complete, and the parts are removed for final inspection.
