Abstract
This article descibes the results of a study that looked at developing methods for efficient management of specialized infoware contained within the automation systems responsible for the fabrication of bimetallic and metal ceramic units for aerospace industry. Theoretical and experimental research suggests that vacuum diffusion welding provides the best technique for obtaining permanent joints in the fabrication of composite components. The results of the research include the following: A database was created for the materials used in aerospace industry and for the diffusion bonding techniques; a search algorithm was developed applicable to the above database, that is based on set process parameters. A method was developed that helps determine what technique was applied for a particular welded bimetallic component. Using this method one can obtain a report that describes the details of the process applied. To implement the resulting technique a trial unit was designed for fabricat-ing composite components by diffusion welding. The proposed CAD technique was tested by way of developing a process of fabricating metal ceramic components, and namely a turbine rotor of the turbine pump and a body of the laser optical transducer. The developed database technique combined with computer-aided design and process control helps save organisational effort and reduce the lead time for high quality components used in aerospace industry.
