Direct laser deposition is used to produce metallurgically well-bonded and higher quality coating by the advantages of reduced production time, enhanced thermal control, small heat-affected zone, and high satisfactory repair of parts. Substrate/clad interface plays a vital role in determining overall performance of the component. Most coating/hardfacing materials research focused on wear and hardness due to thin coated thickness/layer. However, in case where coating/repair area is deeper and larger, thick/multi-layer coating is highly required. Therefore there is lack of knowledge on bonding characteristics/properties of as-deposited nickel-base superalloys on dissimilar substrates. The objective of this study is to investigate fracture behavior of laser deposited Inconel 718 powders on alloy steel substrates hybrid specimens with specific emphasis on adhesion/bonding performance through tensile test. Tensile fracture surface of the hybrid specimens and tensile failure mechanisms will be discussed in detail.
