THE ROLE OF NET SHAPE MANUFACTURE IN REDUCING LIFE CYCLE COSTS OF GAS TURBINE COMPONENTS

摘要

The advent of new material production processes and improved control / prediction of powder consolidation offers the potential for reducing gas turbine life cycle costs. End user requirements in terms of product manufacture and certification will be reviewed with respect to requirements and potential for optimized raw material input morphology and cleanliness. Examples of components where near net shape technology could be applied will be reviewed along with current production and repair practice. This will include electrolytic deoxidation powder routes and metal addition processes for titanium alloys.
