Enhanced Pitting Corrosion Resistance of Nanostructured AISI 304 Stainless Steel via Pipe Inner Surface Grinding Treatment

Round 1

Reviewer 1 Report

This article dealing with the formation of a single-phase nanostructured austenite on the surface of an AISI 304 stainless steel via a pipe inner surface grinding. This article looks very appealing, however, some revisions needs to be done before the publication.

1). Page 2, line 50. Please add a small paragraph depicting the gap between this investigation and the previous work.

2). Page 2, line 66. Could you please provide a photo of device for the PISG processing?

3). Page 2, line 74, How did you determine the parameters for the PISG processing?

4). Part 5, line 261. I guess this part needs to be rewritten. Some quantitive results need to be summarized in this part.

Reviewer 2 Report

The subject of paper is scientifically interesting. However, in order to accept, the paper should be subjected to a careful revision. The detailed remarks are as follows:

- The literature survey presented in paper seems limited. Authors are requested to extend the state-of-the-art by consideration of the newest works within this scope (related to processing of stainless steels and precise machining). Among others, the following ones should be studied and included in a literature survey.

1. 10.1016/j.triboint.2020.106334

- At the end of Introduction please clearly present the novelty of the proposed method towards others in this area.

- In order to improve the readability of conclusions please formulate them in a form of a bullet points depicting the main findings both in the qualitative and quantitative way
