Reviewer 1 Report
Joining of metal to plastic is a hot topic and the authors developed a new method of using roughened Electrodeposited Copper Coating on Steel to improve the mechanical interlock. This manuscript could draw the interests from both the industrial and the academical field. The following suggestions is for reference:
Many other methods have been developed to join metal to plastic, e.g., laser, friction stir welding. What is the advantage and disadvantage of injection molding of the resin compared to these methods?
The representative papers about laser and friction stir welding of dissimilar materials:
A laser joining system for titanium and polyethylene terephthalate plastic controlled by multiple signal sources, IEEE
Joining of metal to plastic using friction lap welding, FC Liu, J Liao, K Nakata
How will the electroplating parameter and the injection modeling parameter affect the mechanical performance of the joint?
Could the authors compare the strength of dissimilar joint in this paper with those reported in the literatures,
Language should be improved.

Reviewer 2 Report
This is intersting work; in paricular, the ability to roughen the surface is of great significance as it can reduce processing time and costs. Some editing is needed as suggested below. In addition, an explanation of how roughening occurs would be useful, while the reasons for galvanic corrosion not having an effect are not clear. My comments are:
- What mechanism leads to roughening?
- There must be some evidence of galvanic corrosion of steel near the cross-section at the contact with copper. It is mentioned that the copper can protect the steel, but at the cross-section between them, galvanic corrosion is likely. Doesn't this affect the bond between steel and copper?
- The captions for figs. 8, 9 and 10 must be placed below the figures.
- Close the brackets in line 253.
- In line 262, correct to "Stress in known..."
- Provide references of the source of the CTE values.
