Гель на основе хитозана и хлорида натрия как тест-система коррозионного поведения сплава AZ91A-ASTM B

Abstract

In this work, acetic acid will be used to dissolve chitosan to prepare a sol, and the chitosan will be gelled by controlling the temperature to evaporate the acetic acid and excess water in the sol. The gel will be used as a quasi-solid electrolyte to simulate the human body environment to evaluate the corrosion resistance of medical alloys. In order to simulate the human body environment more accurately, the main liquid component in the gel will be controlled to be a NaCl solution with a concentration of 0.9 %, and the liquid component will account for 60% of the gel mass. In the work, it is necessary to design a method to evaluate the water content of gel, test and summarize the proportion and preparation process of this kind of gel, and discuss the influencing factors that affect the water content of gel
