电沉积Ni-W-P非晶合金的组织结构与耐蚀性能

Micro Structure and Corrosion Resistance of Electro-Deposition Ni-W-P Amorphous Alloy

研究了电沉积Ni W P非晶合金随热处理温度升高,其结构及耐蚀性能的变化规率。结果表明,镀态Ni W P合金在300℃以下温度热处理后,仍为非晶态;随温度升高开始晶化,到500℃时晶化过程结束;其腐蚀速率随热处理温度的升高增大,于500℃达到最大值,而后降低。

The change laws of structure and corrosion resistance of electro-deposition Ni-W-P amorphous alloy with temperature increasing in heat treatment are studied .The results show that the Ni-W-P plating still holds amorphous state under 300℃ of heat-treatment temperature,but from 300℃ begins to crystallize untill 500℃,meanwhile,its corrosion rate goes high with the temperature increasing up to 500℃,then goes down.
