摘要
Zr-based bulk metallic glass was subjected to electro-less plating of (Ni–P)/graphite composite film in order to avoid cold welding in ultrahigh vacuum condition. The plated film consisted of Ni–P amorphous phase, fine nickel crystals and fine graphite particles. Measurements of the adhesion coefficient between the two sample surfaces contacted in high vacuum indicated that the cold welding phenomenon appeared for the naked surfaces of the Zr-based metallic glass was essentially depressed after the deposition treatment on the surfaces.
