Effects of heating temperatures on the structure and the hardness of amorphous Ni-P alloys with different phosphorus contents hare also been studied.
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。
The results indicate that microcrystalline deposit with low phosphorus content has higher hardness, modulus and fatigue resistance than the amorphous deposit with high phosphorus content.
结果表明，低磷微晶镀层较高磷非晶镀层具有更高的硬度、弹性模量和疲劳抗力；
The paper presents the chemical function of zeolite 4a, the silicate, the amorphous silicate, the layered silicate of green phosphorus detergent and its present development.
