Proposed study
This is a proposed internal development study. Verified parts and results are not yet available.
The brief defines what the study will investigate and measure.
The proposed brief
Compare restoring a defined wear region on a sacrificial shaft demonstrator with manufacturing a replacement. Select a known substrate and compatible deposition route with the specialist partner before developing the restoration geometry.
Design, iteration & manufacture
Establish baseline geometry and material records; machine a controlled wear feature; develop deposition trials on representative coupons; use partner Directed Energy Deposition, such as an appropriate laser metal deposition process; finish machine and inspect. Coordinate the drawings, preparation, deposition, finishing and acceptance records.
What the study will measure
Deposited and removed volume, final dimensions, runout, surface finish, distortion and partner-defined material/bond/defect examinations. Record the actual cost and elapsed time of the complete route. Functional life or fatigue claims require a separate representative programme; a good dimensional inspection alone is insufficient.
Applications for customers
Repair-versus-replacement decisions for industrial rotating equipment and energy maintenance buyers. TWI describes shaft restoration using laser deposition, experimental pieces, metallurgical assessment and finish machining, giving a relevant precedent for the study structure. TWI shaft refurbishment
