Abstract
Hybrid manufacturing is a combination of additive (deposition) and subtractive (machining) manufacturing in a single machine tool. This laser metal deposition process can be used for near net shape manufacturing and component repair using either similar or dissimilar materials. With commercially available hybrid manufacturing systems capable of 5-axis deposition and subtraction, it is now feasible to control the interfacial conditions between substrate and deposition. Other deposition processes require substrates to be planar, but hybrid manufacturing’s subtractive capability allows for unlimited surface structures and conditions. Industry implementation has already occurred in the mold and die repair industry, but it will quickly expand to other applications. This dissertation will evaluate the use of various material and structure combinations to evaluate and enhance the mechanical properties associated with hybrid manufactured components.
