Laser cladding of refractory alloys on titanium alloy surfaces has the potential to enhance surface properties, expanding applications under high-temperature and wear-intensive conditions. By precisely controlling energy distribution and melt pool dynamics, laser cladding can improve the solidification characteristics and compositional distribution of coatings. However, due to the complexity of the rapid melting and solidification process, real-time monitoring of melt pool behaviors is challenging, making numerical simulation an essential tool for investigating melt pool evolution.
