Experimental Study of Electrolytic Processing of Discharge-Assisted Jet Masks

Round 1

Reviewer 1 Report

The manuscript entitled, "Experimental study of electrolytic processing of discharge-assisted jet masks", compares the results of machining a sample using masks and discharges in electrochemical corrosion machining.  First, I though the article was well-written, and the topic is interesting.  I struggled in a couple of areas, though.

1. Is topic of the manuscript suitable for Coatings - or would it better fit in Journal of Manufacturing and Materials Processing, for example?

2. Line 50 - What are the 3 stages?  The description seems to be missing - and are these stages observed in your work?

3. Line 55 - There seems to be a random reference there with no description.

4. Some labels on Fig. 1 would be helpful for the reader to understand what is pictured.

5. The description of the machining process include from line 105-115 needs to be improved.  What is the electrolyte?  How is the flow controlled?  Why is the applied potential difference so large?  What is meant by the electrolyte forms an array of liquid electrodes?  How is the discharge controlled?

6. Where is the superimposed discharge effect in Fig. 3?

7. What is 304 mirrors stainless?

8. Line 138 - What spacing between what holes?  Please provide a better explanation of this process.

9. Line 152 - Explain fixation and its relation to EF.

10. In Figs 6 and following, label the differences as 'discharge' and 'no discharge'.  Labeling with acronym became confusing because the only difference between the acronyms occurs in the 8th character over from the left.

11. In Fig. 9, it's hard to discern any difference between the cross-sections.  Can they be plotted on the same plot so differences are more apparent?

12. In Fig. 10, the craters are substantially deeper for the Jet-MECDM process vs the Jet-MECM process.  Which depth was intended? 

13. Can the authors provide better examples of the potential applicability of this tool? 

Language and writing were fine.

Reviewer 2 Report

The authors have used electrochemical discharge machining in which workpiece is masked.The following clarifications are required from the authors

The authors should add few literatures related to this research in the introduction part

Clearly state the novelty of the research

what is the feed rate of the nozzle?

what is preparation method of electrolyte and why sodium nitrate were preferred?

what is effect of flow of electrolyte in the nozzle?Does any erosion takes place in nozzle?

How did you measure H while calculating the corrosion factor?
