In order to study the evolution laws of the temperature field, flow field, and macroscopic morphology of the molten pool during laser cladding process, this paper focuses on the changes in the morphology and flow field distribution of the molten pool temperature field caused by corresponding parameter changes during laser cladding process. First, a multi-physics field coupling model for laser cladding was established by combining light powder interaction, phase transition, heat transfer, and flu...

The advancements in materials science and engineering, combined with a deeper understanding of atomic structures, have laid the foundation for the emergence of advanced materials.

The continuous energy input can lead to heat accumulation in the multi-pass lap laser cladding, which results in a progressive increase in the dilution rate and deteriorates the quality of laser cladding. Precisely controlling the stability of the dilution in the multi-pass laser cladding is still challenging. In this study, we proposed a deep-learning driven method for precisely controlling the dilution rate in the multi-pass laser cladding. Initially, the relationship between the dilution rate...

The effect of Y2O3 addition on the microstructure and properties of the laser cladded Al-Si alloy coating on the surface of AZ91D magnesium alloy was investigated in this study. The experimental results showed that the Al-Si + Y2O3 cladding layers contained α-Mg, Mg2Si, Al4MgY and a small amount of Al12Mg17 phases. The coarse dendrites, reticulated eutectic structures and massive phases in the coatings tended to be refined and gradually uniformly distributed with the increased amount of Y2O3. T...

People interested in 3D printing are confronted with a seemingly infinite number of 3-letter terms. Our editor tried to provide an overview of current additive metal printing processes and found out that in fact there are not that many.

Here, the heat treatment for FeCoCrNiAl high-entropy alloy (HEA) laser cladding (LC) layer was given at a temperature which is higher than that of the first phase transition. The effects of heat treatment on the phase transition, microstructure and mechanical properties of the LC-ed FeCoCrNiAl were studied. Meanwhile, the LC-ed sample was compared with the casting specimen. The results showed that the cladding layer had lower activation energy of phase transformation, and it had higher proportio...
