“…This Lagrangian method has demonstrated its ability to simulate different physical problems involving large material deformation and mold filling encountered in highpressure die casting [23][24][25], low-pressure vacuum molding [26], and gravity permanent mold casting [27,28], metal forging [29], additive manufacturing [30][31][32][33], cold spray [34,35], thermal spray [36,37], machining [38,39], as well as in high-pressure plastic [40][41][42] or composite injection molding [43]. Despite its promising range of applications, SPH still suffers from key issues that need to be addressed in order to improve its readiness level in order to facilitate its percolation towards other industrial applications.…”

The present work aims to explore the ability to simulate flow patterns and the velocity field in the powder injection molding (PIM) process using the smoothed particle hydrodynamics (SPH) method. Numerical simulations were performed using the DualSPHysics platform. A feedstock formulated from 17-4 PH stainless steel powder (60 vol. % of powder) and a wax-based binder system was prepared to experimentally obtain its rheological properties that were implemented in DualSPHysics using two different viscosity models. The numerical simulations were calibrated, and then validated with real-scale injections using a laboratory injection press. During the calibration step, the feedstock flow momentum equation in the DualSPHysics code was modified and boundary friction coefficients at different injection rates were adjusted to create a frictional effect. During the validation step, these calibrated conditions were used to simulate the flow behavior into a more complex shape, which was compared with experimental measurements. Using an appropriate boundary friction factor, both the frictional effect of the boundaries and the stability of the numerical solution were taken into account to successfully demonstrate the ability of this meshless SPH method. The flow front length and feedstock velocity obtained in a complex cavity were satisfactorily predicted with relative differences of less than 15%.

“…Now, surface modification technologies have been widely studied as an effective way to improve the corrosion resistance of materials. Generally, surface modification technologies include thermal spraying [3], vapor deposition [4], laser cladding [5], electroplating [6], electrophoresis, and other processes. Among them, electrophoretic deposition (EPD), as a green surface treatment technology, has received the attention of scholars.…”

In this paper, TiB2-Chitosan coating was successfully fabricated on the surface of 6Cr13 martensitic stainless steel by electrophoretic deposition. The effects of different deposition voltage and deposition time on the coating morphology were investigated. The adhesion strength of the coating was characterized by Rockwell indentation, and it was proved that the adhesion strength of the coating was within HF1 degree. The corrosion resistance of coatings with different immersion time was studied by electrochemical test. The result shows that the 40V / 60s sample has optimal comprehensive performance, and the TiB2-Chitosan coating can significantly improve the corrosion resistance of the substrate. The corrosion resistance of the coating decreases with the prolongation of the immersion time.
