有文献报道用铝合金制作全口义齿基托。作者研究铝和铝合金在人造模拟介质中的耐腐蚀性。材料和方法用4种模拟生物体液的介质:①2%枸橼酸,②3%乳酸,③人工唾液(0.4%氯化钠、0.4%碳酸钙、0.4%磷酸钙),④蒸馏水。用3种试样:①纯铝,②铝镁硅铬合金,③铝镁钛合金。试样质量135mg,为厚1.5mm圆片,边缘磨光。把试样浸泡在用玻璃瓶装的介质中,在恒温器(40±1.0℃)放置6
It has been reported in the literature to make a complete denture base with aluminum alloy. The authors study the corrosion resistance of aluminum and aluminum alloys in artificial modeling media. MATERIALS AND METHODS Four media for simulating biological fluids were used: ① 2% citric acid, ② 3% lactic acid, ③ artificial saliva (0.4% sodium chloride, 0.4% calcium carbonate, 0.4% calcium phosphate), and ④ distilled water. With three kinds of samples: ① pure aluminum, ② aluminum magnesium silicon chromium alloy, ③ aluminum magnesium alloy. Sample quality 135mg, 1.5mm thick wafer, polished edge. Soak the sample in a glass bottle and place 6 in a thermostat (40 ± 1.0 ° C)
