Machining the Surface of Orthopedic Stent Wire Using a Non-Toxic Abrasive Compound in a Magnetic Abrasive Finishing Process
Round 1
Reviewer 1 Report
- In this study, a magnetic abrasive finishing process was carried out using a non-toxic abrasive compound (a mixture of iron powder, diamond particles, cold cream, and eco-friendly oil) to achieve high surface finishing of orthopedic stent wire. The surface roughness (Ra) of the stent wire was investigated according to various processing parameters: different rotational speeds (500, 1,000, and 2,000 rpm), diamond particle sizes (1.0μm), and three eco-friendly oils (olive oil, grapeseed oil, and castor oil). Paper is valuable and practical.
- In order to confirm whether the wire components changed after the MAF process, energy dispersive X-ray spectroscopy (EDS) testing was performed. According to the result of EDS test, the components of processing oil and the lack of toxic substances on the surface finish of the Ni-Ti stent wire were not found. Thus, grapeseed oil and cold cream may safely be used in an abrasive compound for the MAF process. This paper has clear charts.

Reviewer 2 Report
Authors present a polishing study of dental materials using non-toxic and environmentally friendly materials. The topic is important for practical aspects and innformatino presented will be of interest for the special community. Paper is clear and gives complete set of experimental techniques. Nevertheless, from my point of view there are too many tables and figures. Some figures can be removed and information from tables can be given in the text. Experimental errors are missing in some places. I suggest to revise illustrativee material to make it more solid. There are several issues which should be also considered:
Line 13, abstract: "eco-friendly oil" is not really informative, I suggest to give some information about chemical nature (trade name or formula or so) already in the abstract.
Line 68: Figure 1(?)
Figure 1: I suggest to give principal dimmentions to show how large is the set up.
I am not sure that Fig. 2 and Fig 5 are necessary for the manuscript and can be removed. As well as Table 2 givees no information.
The specification for a "cold cream" should be given in the experimental part. I also suggest to give not weight in mg in table 1 but weight % for all components.
Figure 10b: 49.49+55.51 =/= 100 %
