Abstract:

With the current development in additive manufacturing (AM) processes, such as Laser directed energy deposition (L-DED), efficient usage of raw materials is possible. With the aid of this L-DED process, we aim to develop an efficient way to reduce the use of bronze in worm gears. Our objective is to fabricate worm gears by applying CuSn10 (bronze) alloy onto a stainless steel tooth created through the L-PBF process. We assess the impact of laser power, feed rate, scanning speed, and scanning strategy on the deposition process. The deposited cross-sections undergo analysis for porosity, hardness, dilution, and microstructure at various locations along the tooth profile.
