- Abstract:
- The technology of Cf/SiC ceramic matrix composites joined up with metal were researched and tested to meet the design requirements of high performance and light weight. Several machining methods were compared. The turning quality was improved. The difficulties and solutions for Cf/SiC nozzle turning are discussed. The appropriate turning parameters and angles of turning-tool are proposed. Theoretic analysis and testing results indicate that the reasonable machining method, modified synthetic polycrystalline (PCD) diamond turning-tool, appropriate cooling and lubrication method, accurate turning parameters and turning-tool geometric parameters, perfect turning of ceramic matrix composites nozzle joint can satisfy the requirements of surface quality, and the dimensional and shape accuracy of Cf/SiC nozzle joint can be achieved.
