CVD Technology for Deposition and Infiltration of Coatings onto CMC Components
CMCs attempt to retain the desirable properties of ceramics while compensating for their limitations. Designed for enhanced mechanical and thermal properties, CMC’s have high tensile strength at extreme temperatures, lower density, higher toughness, improved thermal stability, lower thermal expansion, better conductivity, lower oxidation, and greater fatigue durability than their ceramic constituents. Coating preforms with high purity, conformal materials tailored with properties for end use specifications makes chemical vapor deposition (CVD) / chemical vapor infiltration (CVI) the preferred technology. Chemical vapor deposition is a thin coating deposition technology that provides uniform, dense coverage, and conformity over complex 3D surfaces using heat and low pressure, under robust process controls. Many steps in the CMC production process involve CVD techniques. CVD Equipment is a trusted supplier to the aerospace and defense industry for process equipment for CMCs. Materials.
