ABSTRACT

Progress in the manufacturing sector resulted in the need for products with enhanced mechanical properties, corrosion, and heat resistance. Thus, superalloy was produced with desired mechanical properties. Monel Alloy is one of those nickel-based superalloys, commonly used in industry for its high strength and resistance to corrosion. Monel is also acid- and saltwater resistant. Some properties such as gummy behavior and job hardening make machining superalloys by traditional methods difficult. For this purpose, in this analysis, near-dry wire electric discharge machining (WEDM) is chosen for Monel machining. The present research explores the feasibility of nearly dry Monel alloy WEDM using air and deionized water in nebulous or mist form to achieve the optimal surface finish and resolve environmental issues associated with wet WEDM. This work reflects the study of the influence of various input parameters on the output calculated in terms of the rate of material removal (MRR) and surface roughness (Ra). On an inference, near-dry WEDM formed a smooth surface on Monel alloy over traditional WEDM; however, ranges of MRR still elevate their support to wet WEDM.

摘要

制造业的进步导致需要具有增强的机械性能，腐蚀和耐热性的产品。因此，生产具有所需机械性能的超合金。蒙乃尔合金（Monel Alloy）是那些镍基高温合金之一，因其高强度和耐腐蚀性能而在工业中普遍使用。蒙乃尔合金还耐酸和耐盐水。诸如胶粘行为和工作硬化之类的某些特性使通过传统方法加工超级合金变得困难。为此，在此分析中，选择近干丝放电加工（WEDM）进行蒙乃尔合金加工。本研究探索了采用空气和雾状或雾状去离子水的近乎干燥的Monel合金WEDM的可行性，以达到最佳的表面光洁度并解决与湿WEDM相关的环境问题。这项工作反映了对各种输入参数对根据材料去除率（MRR）和表面粗糙度（Ra）计算得出的输出的影响的研究。据推断，近干电火花线切割法在蒙乃尔合金上形成了比传统电火花线切割法更光滑的表面。但是，MRR的范围仍然增加了对湿WEDM的支持。
