Radiation Effect in Ti-Cr Multilayer-Coated Silicon Carbide under Silicon Ion Irradiation up to 3 dpa
Round 1
Reviewer 1 Report
This paper is interesting and can be published in coating after resolve some issues.
-Novelty should be more clear in the induction.
-What is the different between in CVD and PVD? you can add doi.org/10.1016/j.apmt.2021.101142 to give you more information.
Figure 3, can author determine the ratio of elements before and after irradation?
Figure 11, could author provide high magnification of some area from cross-section.

Title: Radiation effect in Ti-Cr multilayer coated silicon carbide under silicon ion irradiation up to 3 dpa, by Ishibashi et al
Minor comments:
- Introduction
- please update the references, use references 2020—2022
-expand the references to add value for readers, e.g. 14-25, 31-40, summarize the benefits, problem or conclusions from these references.
-Considering the lessons learned in the aftermath of the Fukushima Daiichi Nuclear Power Plant accident, please add reference
-Replacement of conventional Zircaloy fuel cladding with the SiC fuel cladding (which has a lower hydrogen generation rate and lower heat of reaction) is expected to significantly decrease the amount of hydrogen generated from fuel claddings by reaction with steam during severe accidents, these sentences is mentioned in abstract section
- Experimental Procedure
2.1. Coating designs
-The Ti top layer forms highly 91
corrosion resistant TiO2 film at the top surface in high temperature water. The Cr bonding layer relieves thermal stress caused by the thermal expansion difference between Ti and SiC, and additionally forms diffusion reaction layers at the interface with SiC by heat treatment., please ad reference
2.2. Specimens
2.2.1. Ti-Cr multilayer coated SiC
The authors mentioned that specimens ’high-purity CVD SiC (Na < 0.01, Co < 0.01, K <
0.05, Cu < 0.05, Zn < 0.05, Mn <0 .01, Fe < 0.05, Cr < 0.1 in wppm”
Please how the purity measured, mention the equipment, accuracy, model, manufacturing company and country.
2.2.2. Ti and Cr bulk specimens
-. The pure Ti and Cr bulk specimens with dimension of 2.0×10.0×1.2 mm3 the same as the Ti-Cr multilayer coated SiC specimen were cut out from a sputtering target of pure …How the specimen cut out, by which equipment.
-
-into figure 2(a-c), please used different line style instead of different colors, to be cleared when black/white printing
- Conclusions
It is better when put in the numbering or bullet style
