查询词典 turbine

ZA alloy is based on Zn and composed of Al, Cu, Mg added as alloying elements. It is a kindof environmental friendly material that possesses characteristics of high strength, better plasticity,excellent wear resisting property, low friction coefficient and high specific strength, low meltingpoint and no magnetic. ZA alloy has been widely applicated in the fabrication of mechanical partsand models, such as bearing, axle sleeve, pressing plate and turbine. However, the joiningproblem of ZA alloy that hasnt been solved has limited its application in some fields.

ZA合金是以Zn为基，添加了Al、Cu、Mg等合金元素，具有强度高、塑性好、耐磨性优良、摩擦系数低及较高的比强度、低的熔点、无磁性等特点的环保材料，广泛应用于制造轴承、轴瓦、压板、涡轮等机械零件及模具等，但由于连接问题没有解决限制了ZA合金在一些领域的应用，也因此成为ZA合金急亟待解决的问题之一。
