Abstract Scope |
Marangoni convection is a surface tension dependent mass transfer process from region of lower to higher surface tension, influenced by temperature and presence of surface-active elements. Tracking the surface oxide particles in the melt pool during the laser powder bed fusion process (LPBF) can be a potential mechanism for assessing the effect of Marangoni convection. This research entails the development of a particle tracking algorithm to track the surface oxide particles in a melt pool. The flow patterns in the melt pool were observed using high-speed camera. Binary images of the melt pool were simulated using MATLAB script based on the experimental observations. Melt pool size, pixel size, size and number of oxides, flow pattern, and particle velocity affected the accuracy of the particle tracking algorithm with pixel size, number of surface oxides, and particle velocity having maximum influence. |
