| Abstract Scope |
The wear phenomenon directly impacts the lifespan of parts, affecting factory production costs. As demand for additive manufacturing (AM) increases, research on wear characteristics becomes essential. Wear behaviors and mechanisms must be understood as physical conditions affect wear resistance. This study analyzes the worn surface and worn surface cross-section microstructures of as-built 316L fabricated using Directed Energy Deposition (DED) under varying time, speed, and load conditions. We conducted a comparative analysis of the specific wear rate and wear behavior of as-built 316L DED specimens. Results showed that the specific wear rate decreased with increased conditions of time and speed, while the condition of load changes had minimal effect. Increased speed and time reduced oxidation and delamination wear on worn surfaces, with the specific wear rate decreasing due to lubrication from fine debris. |
