Abstract Scope |
The influence of pulse shaping and regular pulse on the microstructure and formation of TiC-Fe based cermets are investigated. This research focuses primarily on the process parameters required to produce defect-free (pores and cracks) components and their mechanical properties such as hardness and fracture toughness. To acquire an optimal process parameter, samples were manufactured using pulse shaping technology and a regular laser pulse wave with varying laser peak power and exposure time. No cracks are observed on the surface of the sample processed through pulse shaping indicated that the pulse shaping technique is beneficial for crack elimination and optimal for processing TiC based cermets. Post-processing treatment such as HIP was adapted to study the effect on the microstructure and mechanical properties on the pulse-shaped SLM processed samples. Pulse-shaped laser-produced samples had the highest hardness and fracture toughness (1008 MPa and 16.7 MPaM1/2, respectively) compared to their counterpart without pulsing. |
