Study on Properties of New Mg-Y-Nd-(La+Ce)-Zr Degradable Magnesium Alloy

Abstract

The new Mg-Y-Nd -(La+Ce) -Zr magnesium alloy was taken as the research object to study the types and contents of rare earth alloys. The corrosion properties were studied by scanning electron microscope and electrochemical experiments. The results showed that the new Mg - Y - Nd - (La + Ce) - Zr magnesium alloy had no toxicity to human cells and had ideal corrosion resistance. The mean corrosion rate at 96 h was <0.3mg/(cm2h). The mechanical properties test showed that the new magnesium alloys had good mechanical properties, its tensile strength >220Mpa, elongation >20%.

Porous Mg–Hydroxyapatite Composite Incorporated with Aloe barbadensis Miller for Scaphoid Fracture Fixation: A Natural Drug Loaded Orthopedic Implant

“…To improve the strength and corrosion resistance of a Mg matrix, several reinforcements have been investigated, including metals, ceramics, and polymers [16][17][18][19][20][21][22][23][24][25][26]. Parande et al [27] studied the effect of low-cost eggshells on a Mg-Zn alloy's mechanical and immersion properties.…”

Cerium Compounds Coating as a Single Self-Healing Layer for Corrosion Inhibition on Aluminum 3003

“…Corrosion inhibitors are compounds capable of inhibiting or reducing the corrosion rate when present in small amounts. Among the corrosion inhibitors, salts of rare earth elements, specifically lanthanides, have been identified as an environmentally friendly method and have been previously reported [36][37][38][39][40][41][42]. Hinton (1984) [43] was the first who concluded that rare earth salts act as a cathodic inhibitor on an aluminum substrate, similar to that of Zn 2+ in steel.…”
