Abstract Scope |
With the development of technology, it has become critical to be able to produce parts with complex geometry at once without using other production technology. Additive manufacturing methods have taken their place in the competitive market saving both time and cost. Vacuum brazing of additive manufactured 17-4PH stainless, conventional AISI304 and 17-4PH stainless steel alloys were examined. In this work, parts were brazed under 10-6 Torr, at 1050°C for 20 minutes using BNi-2 filler material. Vacuum brazed parts were examined in terms of microstructure, wetting, and mechanical strength. Wetting behaviour of brazing on different materials was evaluated by measurement of contact angle and wetted area using optical microscopy on different materials. Microstructures were examined by SEM and EDS. Finally, tensile testing was done on joints to evaluate whether the surface roughness and brazing of different materials affects strength of brazed parts. |
