In this investigation, the effects of input parameters of wire electrical discharge machining (WEDM) process such as pulse current and pulse duration on recast layer thickness (RLT) and heat affected zone depth (HAZ) in machining of Inconel 617 was investigated. Also the corrosion behavior of the machined workpiece was studied. The results showed that RLT increased by increasing pulse current, while HAZ decreased after an increase up to 10 A. Recast layer thickness and HAZ increased by increasing pulse duration. Also, results suggest that WEDM increased the corrosion resistance of workpiece.

Inconel 617的WEDM中重铸层，热影响区和耐蚀性的实验研究

在这项研究中，研究了电火花加工（WEDM）工艺的输入参数（例如脉冲电流和脉冲持续时间）对Inconel 617加工中的重铸层厚度（RLT）和热影响区深度（HAZ）的影响。还研究了机加工工件的腐蚀行为。结果表明，RLT通过增加脉冲电流而增加，而HAZ在增加到10 A后才降低。重铸层厚度和HAZ通过增加脉冲持续时间而增加。此外，结果表明，电火花线切割加工可提高工件的耐腐蚀性。
