对含硼化物B2 O3 或Na2 B4O7的镁合金净化熔剂进行研究 ,比较粘度及其对镁合金的净化效果。硼化物熔剂处理镁合金液后 ,铁含量有大幅度降低 ,夹杂也有明显减少。镁合金的抗腐蚀性能和力学性能得到提高。但是含B2 O3 熔剂较高的粘度使其净化效果相对较差
Study on flux of magnesium alloy containing boride B2 O3 or Na2 B4O7 to compare viscosity and purify effect of magnesium alloy. Boride flux treatment of magnesium alloy solution, a significant reduction in iron content, inclusions also significantly reduced. Magnesium alloy corrosion resistance and mechanical properties are improved. However, the higher viscosity of B2O3 flux makes its purification effect is relatively poor
