The Influence of the Chrome Layer Thickness on the Physical–Mechanical Properties of Steels
摘要
The work reveals the importance of the chromium layer deposited on steel to improve corrosion resistance. This corrosion resistance of the chrome material depends, among other things, on the thickness of the chrome layer. The chrome layer, in turn, is influenced by the parameters of the chrome plating bath (the intensity of the currents used, the advance of the material through the chrome plating baths, the temperature of the bath, the concentration of the solutions, etc. Undesirable problems such as matt deposition, milky white chromium deposition, insufficient thickness and hardness are the most common problems faced in the electroplating industry (Bayramoglu et al. in J. Mater. Process. Technol. 203:277–286, 2008). The material subjected to adhesion, microscopy, and hardness is a 38MnVS6 alloy steel used to make the rod of hydraulic cylinder. The influence of deposited layer thickness was also investigated on the corrosion resistance in salt fog.
