在控制Ｐｄ复层与Ｎｉ芯同步延伸的情况下，Ｐｄ的复层厚度和重量百分比可以控制。Ｐｄ／Ｎｉ复合丝材的室温和高温强度性质都远高于纯Ｐｄ丝，接近Ｎｉ芯的强度性质。Ｐｄ／Ｎｉ复合丝材在高温的界面扩散具有Ｎｉ向表层迅速扩展特征，且符合ξ＝Ｋｔ￣（１／３）规律。
In the case of controlling the simultaneous extension of the Pd cladding and the Ni core, the cladding thickness and the weight percentage of Pd can be controlled. The properties of Pd / Ni composite wire at room temperature and high temperature are much higher than the pure Pd wire, close to the strength of the Ni core. The diffusion of Pd / Ni composite wire at high temperature has the feature of rapidly expanding Ni to the surface and meets the rule of ξ = Kt¯ (1/3).
