Reviewer 2 Report

Comments and Suggestions for Authors

        Corrosion processes are complex in nature and their studies had become an interdisciplinary research field, combining fundamental sciences and engineering. As quantification of corrosion processes are affected by many variables, standard guidelines to study such phenomena had been developed, such as ASME or ISO, and are broadly used by industry and academics. They describe methods to perform immersion test experiments and to quantify the corrosion rates of metals exposed to corrosive environments but do not provide any guidelines for post-exposure analysis of the as-obtained corroded samples, which might provide useful information to understand the underlying physicochemical mechanisms of corrosion. This knowledge is useful for selecting the right materials of construction and to develop corrosion prevention strategies. In this work, a semi-quantitative-categorization method of the corrosion behavior of metals exposed to a corrosive medium based on their mass loss and aspect is presented. For each category, the mathematical aspects of gravimetric measurements of mass change rate and the analytical techniques that can be used for the characterization of materials are discussed. The following method do not intend to replace industrial standards but to expand them in order to maximize the amount of information that can be extracted from immersion tests.

I express gratitude to the reviewer for dedicating time to review the paper. A revised version of the manuscript is currently in progress, incorporating corrections and addressing points raised during the peer-review process.

Reviewer 3 Report

Comments and Suggestions for Authors

Interesting academic review of corrosion studies with Immersion Test and gravimetric analysis. I would like only to ask the Author to enrich  his next papers with other applications in gravimetric analysis: water vapour transmission (loss of water weight); transmission of other vapours; impurites and solutes uptake; polymer (or metal, composites) decomposition; degradation; environmental stability and protection. These topics will make that kind of analysis valuable not only to corrosion scientists but to much bigger number of scientists.

Author Response

I would like to express my gratitude to the reviewer for investing time in reviewing my article. The classification method was developed to address corrosion problems, with a deliberate effort to ensure its broad applicability across diverse scenarios. I also acknowledge its potential utility in categorizing the degradation behavior of non-metallic materials. A corresponding statement will be incorporated into the summary section. I sincerely hope that this method contributes significantly to gaining a deeper understanding of material degradation phenomena. Thank you for your constructive feedback, which has contributed to the enhancement of the manuscript.

Reviewer 4 Report

Comments and Suggestions for Authors

The author has presented a Semi-quantitative Categorization Method for the Corrosion Behavior of Metals Based on Immersion Test. This article is not very novelty, because there are many such articles and one manuscript is almost general. Many parts of this manuscript have been reported in other articles. However, it does not detract from the value of your manuscript. The author should improve the quality of the presentation. Add graphics or Figures to the manuscript. The author should add more references related to the topic. Try to report the sections in more detail and avoid generalizations. Therefore, the author needs to revise it thoroughly. This study is unfortunately unpublishable in its current state.

Author Response

I appreciate the reviewer for the feedback. An extensive literature review has been conducted, emphasizing efforts to develop Categorization Methods for the Corrosion Behavior of Metals, primarily relying on electrochemical measurements. Those based on Immersion Tests depend on corrosion rate quantification and are typically designed for specific contexts (alloy and corrosion environment). The method has been intentionally kept general to cover a range of situations.

The following improvements have been implemented:

1. A section reviewing classification methods and references to related topics has been added.
2. An additional figure summarizing corrosion behaviors has been included.
3. More contexts on potential uses of the method, including non-metallic materials, have been incorporated.

I would like to express gratitude to the reviewer for their feedback. A new version of the manuscript is currently being prepared.

Reviewer 5 Report

Comments and Suggestions for Authors

The manuscript has been well organized and written. I think that it can be accepted after a minor revision.

1. Please pay attention to the punctuation mark;

2. Could the author supply some experimental data to support present designs?

3. Please add more references in the manuscript. 

Author Response

I extend my appreciation to the reviewer for dedicating time and providing valuable feedback.

1. Corrections have been made to punctuation marks and other typographical errors.

2. Regarding experimental data: This article outlines a method for classifying corrosion behavior. The method is being applied to categorize the corrosion behavior of metals exposed to ionic liquids. Analysis based on this method will be featured in upcoming papers as experimental corrosion data from these studies become available in peer-reviewed papers.

3. Acknowledged. More recent and pertinent references have been incorporated into the manuscript.

Thank you for your constructive feedback, which has contributed to the enhancement of the manuscript.

Reviewer 4 Report

Comments and Suggestions for Authors

Thank you for the changes you made to the manuscript. The manuscript has found a suitable structure. But it still needs improvement for publication. For the last time before publishing, I have some suggestions for you that will be very helpful in improving the manuscript and I ask you to implement them.

1. In the section 2.4 (Surface analysis):
Please prepare a Table and briefly explain the advantages and disadvantages of each method.

2. In the section 4 (Classification method disambiguation):
Please add a schematic and briefly name the important factors.

3. Improve the quality of Figure 3.

Author Response

Dear Reviewer,

I want to express my gratitude for your valuable feedback, and I apologize for the delay in my response. After careful consideration, I have implemented the following revisions:

In section 2.4 (Surface analysis): I have added a table in the Appendix summarizing the various surface analysis methods along with their respective advantages and disadvantages. This table offers a concise comparison to aid readers in understanding the strengths and limitations of each method.

In section 4 (Classification method disambiguation): I have included a schematic diagram to accompany the discussion on classification method disambiguation. This schematic highlights the important factors involved in the classification process, providing a visual aid to complement the textual explanation.

Figure 3: I have improved the quality of Figure 3 to enhance its clarity and readability. The revised version of Figure 3 can now be read in the PDF at 100% zoom. If further modifications to Figure 3 are necessary, please let me know.

I believe these revisions will significantly enhance the clarity and comprehensibility of the manuscript. Thank you once again for your insightful feedback, which has contributed to the improvement of this work.

Sincerely,

Francisco Malaret
