【摘要】 本文系统地研究了随着磷含量的改变,电刷镀镍磷合金镀态的表面,平截面和纵截面的金相形貌。并测定了加热温度对不同磷含量的非晶镍磷合金的组织结构和硬度的变化规律。更多还原

【Abstract】 The surface appearances as well as the microstructures in sections parallel and vertical to the surface of the Ni-P brush plating have been systematically studied under variant phosphorus contents. Effects of heating temperatures on the structure and the hardness of amorphous Ni-P alloys with different phosphorus contents hare also been studied.更多还原
