Abstract

Nickel–Chromium (Ni-Cr) foam is a highly versatile material, combining excellent high-temperature and corrosion resistance with lightweight and energy absorption properties, making it a popular choice for a wide range of applications. This study explores the development of Ni-Cr foam using Pulse electrodeposition techniques, specifically ultrasonic-assisted pulse electroplating of nickel (UAPEPN) and ultrasonic-assisted pulse electroplating of chromium (UAPEPCr). The study evaluates the surface morphology, coating thickness and minimum mass gain of Ni-Cr foam after each process. A dedicated test rig was designed to measure the pressure drop across the foam, revealing a pressure drop of 0.29 bar at an input pressure of 70 PSI and a flow rate of 17.53 LPM of oil. The porosity percentage and permeability of the foam were evaluated at each developmental stage, with values noted as 91% and 1.0032 × 10−8 m2, respectively, after the UAPEPCr stage. Uniaxial tensile and compression tests were conducted to measure the foam’s maximum strength and energy absorption per unit volume, yielding valuable insights into the material’s performance characteristics.

利用脉冲电沉积技术开发的用于过滤应用的开孔镍铬泡沫的合成与表征

镍铬（Ni-Cr）泡沫是一种用途非常广泛的材料，它兼具优异的耐高温和耐腐蚀性能以及轻质和能量吸收特性，因此在各种应用中都很受欢迎。本研究采用脉冲电沉积技术，特别是超声波辅助脉冲电镀镍（UAPEPN）和超声波辅助脉冲电镀铬（UAPEPCr），探索泡沫镍铬的开发。研究评估了每种工艺后镍铬泡沫的表面形态、涂层厚度和最小质量增益。设计了一个专用测试台来测量泡沫的压降，结果显示，在输入压力为 70 PSI 和油流速为 17.53 LPM 时，压降为 0.29 bar。在每个开发阶段都对泡沫的孔隙率和渗透率进行了评估，在 UAPEPCr 阶段之后，评估值分别为 91% 和 1.0032 × 10-8 m2。还进行了单轴拉伸和压缩试验，以测量泡沫的最大强度和单位体积的能量吸收，从而对材料的性能特征有了宝贵的了解。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
