Diffusion couple technique has been utilized to study the interdiffusional behaviors of Zn–Cr system. Two intermetallic compounds (Zn₁₃Cr, Zn₁₇Cr) have been found in the diffusion zone between 598 K and 653 K. For the existence of Zn₁₃Cr phase, the incremental diffusion couple has been used to confirm, and the results show that the Zn₁₃Cr phase can be determined in the present work. However, the thickness of Zn₁₃Cr is very thinner than that of Zn₁₇Cr, which indicate the growth of Zn₁₃Cr is very slow. The thickness of Zn₁₇Cr satisfied the parabolic growth law. EPMA was used to obtain the composition profiles and the interdiffusion coefficients of Zn₁₃Cr, Zn₁₇Cr and Zn (hcp) have been extracted by forward simulation analysis embedded in ‘Pydiffusion’ code. The mechanical properties of Zn₁₇Cr were also determined by nanoindentation technique, and the hardness and Young's modulus of Zn₁₇Cr is 3.01 GPa and 165.78 GPa, respectively.

扩散偶技术已被用于研究Zn-Cr 系统的相互扩散行为。在 598 K 和 653 K 之间的扩散区发现了两种金属间化合物（Zn ₁₃ Cr、Zn ₁₇ Cr）。对于 Zn ₁₃ Cr 相的存在，采用增量扩散偶来证实，结果表明：在目前的工作中可以确定Zn ₁₃ Cr 相。然而，Zn ₁₃ Cr的厚度比Zn ₁₇ Cr的厚度要薄得多，这表明Zn ₁₃ Cr的生长非常缓慢。Zn ₁₇的厚度Cr 满足抛物线增长规律。EPMA 用于获得成分分布，并且通过嵌入“ Pydiffusion ”代码的正向模拟分析提取了Zn ₁₃ Cr、Zn ₁₇ Cr 和 Zn (hcp)的相互扩散系数。锌的机械特性₁₇的Cr还通过纳米压痕技术测定，且硬度和Zn的杨氏模量₁₇ Cr是3.01 GPA和165.78 GPA，分别。
