Round 1

Reviewer 1 Report

This manuscript is about the “Comparative Investigation on Biocompatibility of Stainless Steels Coated with TiN, TiCN, and Ti-DLC Films” which are presented by J. Lou et al. They have published a similar coating condition entitled “Comparative Investigation on the Tribological Performances of TiN, TiCN, and Ti-DLC Film-Coated Stainless Steel” by DOI: 10.1007/s11837-019-03718-y. However, here the biocompatibility of AISI 316 L, is investigated. The subject is interesting but some modifications are required.

- Writing must be improved.

- The abbreviations in the first presentation should be correctly defined.

- 316 L SS in the standard writing is AISI 316 L.

- In the abstract, the novelty is better highlighted by the quantity statement.

- at Introduction mention the effect of Cr and Mo on toxicity.

- The adhesion of the coating to the substrate is unclear.

- A corrosion test is highly recommended (potentiodynamic corrosion test)

- The polishing procedure must be defined. (Experimental)

- Figure 4 is unclear. (biocompatibility assay)

- The role and contribution of the TiC nanocluster must be demonstrated sharply. (conclusion)

- The effect of substrate is unclear.

Reviewer 2 Report

Authors should add to the title 316 L 

...316 L Stainless Steels Coated with TiN, TiCN, and Ti-DLC Films

There is no data on substrate 316 L  it is very important what was the thermal heat treatment of the initial substrate before  PVD. 

There is also no data on the PVD what kind of PVD do you use  - sputtering??

In dental medicine usually use 304L while in orthopedics 316 L SS is the right one

Please  explain which standard   you use for cytotoxicity -biocompatibility assessment

 ISO 10933-5   

The manuscript is very similar to Comparative Investigation on Corrosion Resistance of Stainless

Steels coated with Titanium Nitride, Nitrogen Titanium

Carbide and Titanium-Diamond-like Carbon Films
