Abstract The effect of surface roughness of H13 steel on chromium coatings’ structure and properties was investigated by surface morphology and structure analysis, electrochemical impedance and polarization curve testing. The results show that when the electrodepositing time is less than 30 min, with the increase of the surface roughness of steel matrix, the grain size of chromium coatings decreases, and the grain accumulation becomes sparse; when the electrodepositing time is 30 min, the grain size and distribution of chromium coatings obtained under different surface roughness are same; when the time is more than 30 min, with the increase of the surface roughness, the grain size of chromium coatings increases obviously. When the surface roughness value Ra is less than 0.504 μm, the advantage growth surface of chromium grain is (200), and when Ra was 0.504 μm, the advantage growth surface of chromium grain changes to (211); the thickness and the microhardness of chromium coatings increase with the increase of electrodepositing time; with the reduce of surface roughness at a same electrodepositing time, the thickness of chromium coatings decrease, the microhardness increases, and the corrosion resistance of chromium coatings gradually increases.
