主 题：Magnesium alloy Zinc calcium phosphate Biocompatibility Corrosion Strontium Cell viability
摘 要：The effect of strontium doped Zn-Ca-P(ZCP)coating by chemical conversion technique on the biodegradation of AZ31 alloy was *** coating formed with 1.5 wt.%Sr and 20 min phosphating time at 50℃ with pH 2.5 completely covers the alloy *** Sr doped coated sample also showed very low evolved hydrogen gas and pH change than the ZCP coatings suggested that the degradation of the alloy was extremely *** in vitro bioactivity studies in simulated body fluid exhibits deposition of calcium phosphate phases with Ca/P ratio of 1.55 which is close to that of hydroxyapatite,mineral component of *** evaluation with L929 cells showed higher cell viability of the Sr doped coatings compared to ZCP coatings.
