摘要：

Laser engineered net shaping (LENS (TM)), a metal additive manufacturing process, was employed to repair internal defects in Inconel 718. The technique involves milling slot/s around defect zone and subsequently refill the cavities with a material. This study investigates the effectiveness of two slots with different geometric shapes, rectangular and trapezoidal, to repair internal cracks and understand the influence of deposition orientation on mechanical properties of the repaired components. Trapezoidal shaped cross-section showed good fusion between deposit material and the part along the sidewalls without any void inclusion. Build-direction, especially diagonal-deposition, influenced coefficient of friction and compound-wear for non-heat-treated samples. (C) 2019 Elsevier B.V. All rights reserved.
