采用座滴试样比接触面积法研究了Ｃｕ－Ｃｒ合金与柔性石墨和炭片的润湿性．Ｃｒ含量愈高，座滴与炭石墨材料的比接触面积愈大，接触角愈小．
The contact area method was used to study the wettability of Cu-Cr alloy with flexible graphite and carbon sheets. The higher the Cr content, the larger the specific contact area between the droplet and the carbon graphite material, the smaller the contact angle.
