摘要
采用自制的喷射装置将Co_3O_4和T_iO_2粒子分别喷入锌铝合金(ZA—12)中,研究了它们对该合金的机械性能的影响效果。实验结果表明:喷射CO_3O_4和T_iO_2粒子能有效地提高合金在室温和100℃下的综合机械性能,特别是高温性能。进一步的观察和分析表明:弥散分布在基体中的氧化物粒子是提高合金机械性能的原因。
The Co3O4 and TiO2 oxide particles are sprayed respectivelly into ZA- 1 2 alloy with an installation made in the laboratory and their effects on the alloy' s mechanical properties have been studied. The experiment results show that the particles sprayed can effectivelly raise the alloy s mechanical properties at room temperature,and at 100℃.especially at high temperature. Through further observations and measures.shown that the Co3O4 and TiO2 particles dispersed in the matrix are the cause tc strengthen the alloy.
