This article by orthogonal experimental method to determine the composition of chromate conversion and use of electrochemical method of electrochemical corrosion of the film discussed the substrate in different components, content, time and pH of chromate conversion coating of corrosion resistance. Orthogonal to determine the best experimental chromate conversion solution by adding the rare earth element cerium and lanthanum salt, and discuss the effects of rare earth elements cerium and lanthanum chromate conversion film on the anti-corrosion. The results show that in CrO3 5.4 g/L, NaF 0.5 g/L, K3Fe (CN)6 0.5 g/L, pH 1, conversion time is three minutes, there is a better corrosion resistance. The rare earth elements in a chromate conversion solution, La2(CO3)3 to 0.2 g/L chromate conversion coating of the anti-corrosion better.

Effects of different rare earth elements on the degradation and mechanical properties of the ECAP (equal channel angular pressing) extruded Mg alloys were investigated in this work. Microstructural characterization, thermodynamic calculation, a tensile test, an electrochemical test, an immersion test, a hydrogen evolution test and a cytotoxicity test were carried out. The results showed that yttrium addition was beneficial to the improvement of the alloy’s strength, and the ultimate tensile strength (UTS) and yield strength (YS) values of the ECAPed Mg-2Zn-0.5Y-0.5Zr alloy reached 315 MPa and 295 MPa, respectively. In addition, Nd was beneficial to the corrosion resistance, for which, the corrosion rate of the ECAPed Mg-2Zn-0.5Nd-0.5Zr alloy was observed to be 0.42 ± 0.04 mm/year in Hank’s solution after 14 days of immersion. Gd was moderate in improving both the corrosion resistance and mechanical properties. Moreover, after co-culturing with murine calvarial preosteoblasts (MC3T3-E1) cells, the ECAPed Mg-2Zn-0.5RE (Nd, Gd, Y)-0.5Zr alloys exhibited good cytocompatibility with a grade 1 cytotoxicity. Consequently, the ECAPed Mg-2Zn-0.5Nd-0.5Zr alloy showed the best application prospect in the field of orthopedics.
