<正> Bagley 和 Turnbull 指出含磷14.9wt-%的非晶 Ni-P 镀层在加热过程中,280和410℃有两次放热转变,分别对应非晶亚稳转变及 Ni_3P 相结晶转变.我们对含磷为15wt-%的 Ni-P 非晶镀层进行热分析时发现,在加热过程中有四次明显的放热转变,其对应的温度分别是280,310,343,410℃.为了确定这些放热转变对应的结构变化,本文对3组 Ni_(75)P_(25)试样进行不同热处理后,作 X射线衍射分析,发现310℃和343℃的两次放热转
Four exothermal peaks at 280,310,343 and 410℃ are revealed on the crystallization of the electrodeposited amorphous Ni_(75)P_(25) film examined by DTA.X-ray diffraction shows that the exothermal peak at 310℃ corresponds with the phase transformation from the meta- stable phase α to ones α_1,α_2 and α_3,and peak at 343℃ is related to the adjustment of α_1, α_2 and α_3 each other.
