The Effect of Addition of Nanoparticles, Especially ZrO2-Based, on Tribological Behavior of Lubricants
Round 1
Reviewer 1 Report
I found this paper a little awkward in part because it is classified as a review, but it also contains some original results. I would suggest publishing the new experimental results as a short research paper and revising the review article to include that reference. I think this would make the paper flow better.
There were segments of the paper that I felt could use editing by someone who is fluent in English. For example the first sentence of section 1.1 is awkward. I would also like to see the very short paragraphs (lines 54-57) reworked. It appears that something is missing in this area. There appear to be similar disconnects in other areas of the paper (lines 146-155), (lines 165-174). Sections like this could easily be rewritten in to a paragraph ar two that would make more sense.
Author Response
Dear Sir/Madame,
thank You, very much, for your review.
We really appreciate your advice to publish the new experimental results as a short research paper and to include that reference in the review paper.
However, creating a separate short research paper and publishing it involves:
- extension of publication time (we cannot predict it) - even if the Lubricants Editors would agree to such a solution,
- additional fees associated with the Open Access option.
We have asked the Editor for suggestions on the type of article, but have not obtained any. So we decide to make compromise and make that part much shorter in our review paper.
English has been corrected and the parts, You have kindly suggested, have been modified and extended. Thank You very much for such suggestions.
Thank You, very much, for your valuable help and patience.
Best regards

Reviewer 2 Report
First, as a review article, the content of this paper does not correspond to lts title very well. For example, the research and application of ZrO2 are relatively few, so it is suggested to modify the topic or supplement the content.
Second, there are many kinds of nanoparticles used in grease, but relatively few study of ZrO2. The author should to introduce the reasons for choosing this type of nanoparticles.
Third, the difference between "aggregation" and "aggregation" was explained, but the cited literatures were introduced simply and no specific characterization and test results described, which affects the value of this review paper.

Dear Sir/Madame,
thank You, very much, for your review.
We really appreciate all your advice.
We have changed slightly topic.
We have explained why we have chosen ZrO2 nanoparticles.
We decide to make a compromise and make the experimental part much shorter in our review paper.
English has been corrected and the parts, You have kindly suggested, have been modified and extended aspecially this concerning 'aggregation' and 'agglomeration'. Thank You very much for your suggestions.
Thank You, very much, for your valuable help and patience.

Reviewer 3 Report
In the paper “The effect of ZrO2 nanoparticles agglomeration on the friction in greases containing them”, the effect of the agglomeration of ZrO2 nanoparticles on the tribological behavior of grease is discussed.
In this review, grease lubrication, concepts as agglomeration and aggregation, the role of nanoparticles in the lubrication and methods used to prepare these nanoparticles are discussed, resulting in a very interesting paper.
However, some aspects should be improved in order to publish this paper:
-English language and style must be improved. Some parts of the paper are difficult to understand, there are spelling mistakes (e.g. “or a” in line 199, “According to studied” in line 225, “ was studied”, “Varder-waal” in line 452 or “Thera are” in line 326).
- It is necessary to review subscripts and superscripts in the chemical formulas in all the document.
-Units of concentration must be the same (M or mol·L-1).
-Sometimes it is possible to observe the mass percent as “ w.t.%”, while in occasions can be read as “wt%)
-Authors of Reference [70] are not Rosa et al (line 340)
-From my point of view, sections 3 and 4 (Materials and Methods for the Tribological Study and Results) should not appear in a review article. In fact, most of these results and figures 1, 2, 3 have already been depicted in ref 54, so I propone to remove them. In a review article that sections are not necessary.
-Figures in sections 1 and 2 should be included.
Author Response
Dear Sir/Madame,
thank You, very much, for your review.
We have decided to make a compromise and to make that experimental part much shorter in our review paper. Also, some Figures have been removed.
Incorrect reference and units have been corrected.
We have added two figures in section 1. Due to the relatively high costs of obtaining permissions, we have had to limit the number of Figures from the outer resources.
English has been corrected and the parts, You have kindly suggested, have been modified and extended. Thank You very much for such suggestions.
Thank You, very much, for your valuable help and patience.

Round 2
Reviewer 1 Report
The manuscript looks to be ready for publication. I did notice that in line 178 ToO2 should be TiO2.
Other than that, I think this manuscript is a valuable contribution to the field.

Reviewer 3 Report
Authors of the paper “The effect of addition of nanoparticles, especially ZrO2-based, on tribological behavior of lubricants” have considered some of the suggestions provided and have extended the information in the paper.
I have few comments to improve the quality of the paper:
- I do not understand the abbreviation “a.o.” in line 11.
- Image resolution in figure 3 should be improved.
- Reference 14 format must be reviewed.
- Chemical formulation should be reviewed, for example in lines 178, 755, 775, 776.
Author Response
