Chemical Vapor Infiltration (CVI)

Chemical Vapor Infiltration is a method of producing ceramic matrix composites in which reactant gases are diffused into a porous substrate and deposited. The resulting deposition reduces the substrates porosity; increasing density. The densification stops once the pores are fully closed.

TevTech CVI systems can be either vertical or horizontal configuration and come standard with a flow enclosure for preform placement and precursor injection which assists in temperature uniformity and containment of the deposition. Our gas distribution systems include a cabinet, MFC's and coriolis MFC's and vaporizer depending upon process gases. Vacuum pump selection is based upon process gases, flow rates and desired operating pressure. Process control is provided by a PLC and touch screen interface. Process recipe programing for automated control and data acquisition is included. Alarms and interlocks for safety, process deviation and equipment protection are also standard.    

TevTech can custom design any derivative of CVI system so you can enhance the qualities and functional characteristics of your advanced materials.
