Pd-In合金的色度测量

Measurement of Chromaticity of Pd-In Binary Alloys

用孟塞尔颜色系统和ＣＩＥ 色度学系统研究不同Ｉｎ 含量的Ｐｄ － Ｉｎ 合金的颜色变化及退火温度的影响， 发现含３６ ％ ～６０ ％ （ｗｔ％ 下同） Ｉｎ 的Ｐｄ － Ｉｎ 合金呈黄色或黄红色。在低温区观察Ｐｄ － Ｉｎ 合金的颜色变化， 随着退火温度的升高， 合金的彩度提高， 对光的反射率和明度反而降低。

The colour characteristics of binary Pd-In alloys with different In contents were measured by Munsell and CIE colorimetric systems.The dependences of chromaticity of the alloys on the annealing temperatures were studied.It was found that the Pd-In alloys containing 36～60wt% In show yellow or yellow-red.With the increase of annealing temperature,the chroma of alloys increased,whereas the reflectivity and luminosity decreased.
