Reviewer 1 Report
The article Study on Preparation of micro-arc oxidation film on TC4 Alloy with Titanium Dioxide Colloid in Electrolyte shows the studies of the preparation of micro-arc oxidation film using nano-titania colloid electrolyte. The film properties and microstructure were studied depending on titanium dioxide concentration. The work is completed by the appropriate conclusions. I have some other suggestions for the improvement of the paper which are shown further.

Reviewer 2 Report
The paper describes the Study on Preparation of micro-arc oxidation film on TC4 Alloy 2 with Titanium Dioxide Colloid in Electrolyte. It is well written and good quality paper. Before publication, some changes should be made
In the introduction, the last phrases are: Without introducing new corrosion factors, the thickness, structure, wear resistance and corrosion resistance of the nano-titania col-54 loid on the micro-arc oxidation film of TC4 alloy were systematically studied. Impact. I think that something is missing here. There are several typing errors- Authors should check the manuscript carefully.
Some references should be added to improve this part of the paper.

Response 1: Please provide your response for Point 1. (in red)
1.As your suggestion, the last paragraph of Introdution was modified in manuscript in red, as follow:
Among them, electrical parameters and electrolyte composition are the main factors affecting the performance of the micro-arc oxidation film. The current research direction is mostly to adjust the electrical parameters and adjust the composition of the electrolyte [5]. Additives can affect or participate in the process of micro-arc oxidation, thereby affecting the performance of the film [6]. However, there are relatively few reports on adding colloidal additives to electrolytes. In the reason of the nano-titania colloid has higher surface activity and dispersibility, and the anatase crystal has higher chemical activity at high temperature, which makes it easier to participate in micro-arc oxidation [7]. The anatinite-type nano-titania colloid was added to the silicate electrolyte system, in order to improve the mechanical properties of the micro-arc oxidation film in this experiment.
Since the main component of the film is titanium dioxide, the addition of nano-titanium dioxide colloidal additives will not introduce other impurities, and it is difficult for the micro-arc oxidation film to undergo chlorination and oxidation reac-tions[8]. In addition, there is no potential difference between the nano-titania colloid and the micro-arc oxide film, which makes the electrochemical corrosion of the micro-arc oxide film more difficult[9-10].
The thickness, structure, wear resistance and corrosion resistance of the nano-titania colloid on the micro-arc oxidation film of TC4 alloy were systematically studied.
