ADVANCED MATERIALS & PROCESSES | JANUARY/FEBRUARY 2024 23 A failed pump stalls the entire process. Therefore, between reactors and pumps, it makes sense to install a subsystem for quenching gases, cropping solid byproducts, or filtering byproducts. All of these systems (CVD/CVI/ CMC) require a stringent commitment to safety due to the presence of hazardous gases such as hydrogen chloride, hydrogen sulfide, phosphine, and boron chloride. These gases are often toxic, corrosive, and explosive. The provider of CVD coating systems supplies the gas cabinet with all the required safety devices (e.g., venting and gas detection) to adhere to ATEX directives. Throughout the CVD process, precise control of gas flow, temperature, and pressure is needed for the chemical deposition to occur and accordingly, supervisory control and data acquisition (SCADA) systems are integrated for control and safety. To date, processes and equipment have been developed for an extensive number of advanced coating materials. These include TiC, TiN, Ti(CN), PyC, SiC, B4C, TiB2, BN, Al203, AIN,W, Re, ZrC, TaC, HiC, DLC, ZnS, ZnSe, and doped aluminizing. As engineers and scientists seek to solve some of the industry’s toughest challenges, the use of custom coating systems along with exotic materials will play an increasingly important role. ~AM&P Note: MPA Industrie is a physical and chemical engineering provider of CVD coating systems and ceramics and fiber matrix composites based in France. MPA was recently acquired by global industrial process provider PVA TePla. The company has a 30-year history specializing in advanced materials processing, including manufacturing specialized CVD reactors.
