Damping behavior and energy absorption capability of porous magnesium

Porous magnesium loaded with gentamicin sulphate and in vitro release behavior

“…The preparation process of the p-Mg included three steps: firstly preparation of the entangled porous titanium (p-Ti), then infiltration of magnesium melts into the p-Ti to form titanium-magnesium composite, and finally removal of the titanium wire by using the chemical etching to from the p-Mg. The detailed fabrication method was described in the previous paper [27,28]. In this study, the shape of pores in the p-Mg was copied from the shape of titanium wire in the as-prepared p-Ti.…”

Current Status and Recent Developments in Porous Magnesium Fabrication

“…There are many other mechanical parameters for foam that are determined by porosity and pore size (diameter). Young's modulus, peak stress, and the energy absorption capability increase with decreasing pore size and porosity, [2,63] while Vickers hardness decreases with increasing pore size. [34] Compression strengths also reduce with increasing pore size.…”

“…Each of them was attached by hot glue to one side of a sprue. The entire system was coated with low-refractory slurry [63] , b) porous magnesium after etching of titanium wires. Reproduced with permission from ref.…”

“…Another property of porous magnesium is its damping capacity. The research was carried out on lotus-type magnesium, [12] magnesium with an entangled structure, [63] and syntactic foams with SiC particles. [44] With lotus-type magnesium, vibration-damping capacity was investigated by using hammering-vibration-damping test.…”

Synthesis and characterization of a novel polyurethane curing agent modified by a diazafluorene derivative

“…15,16 To improve the usability of PU in damping conditions, in recent years, researchers have tried to increase PU's content of soft segments by introducing polyester or polyether oligomers and by means of interpenetrating polymer networks. [17][18][19][20][21][22] However, increases in the soft segment result in poor mechanical strength, a weakened usability of PU under higher temperature conditions, and a more complex preparation process because of the introduction of interpenetrating polymer networks. [14][15][16][23][24][25] Lili et al 13 modified PU with polyhydric alcohols, and their results show that the damping capacity and volume shrinkage of the material were enhanced; this was accompanied by decreased thermodynamics and pencil hardness.…”
