Plasma electrolytic oxidation

Time:2019-07-19 10:02:35  From:  Author:

      Plasma electrolytic oxidation (PEO) is the method of choice for this case, since oxide-ceramic coatings of several ten to hundred microns of thickness with excellent coating/substrate bonding and high hardness are generated during this process. rather high electrical energy consumption of the process is admittedly a drawback, the operating materials (electrolytes) are usually environmentally friendly. PEO is a conversion coating process, which means that the metallic substrate is consumed for the production of the oxide ceramic coating under discharge action . Thus, alloying elements in the substrate play a crucial role during the formation of the oxide coating and hence affect the structure of the coating, its composition, and its properties. The effect of the substrate alloy on the service properties of the PEO coatings has, however, been insufficiently addressed until now. Therefore, the current work utilizes a PEO process in alkaline silicate solutions with bipolar-pulsed current to investigate the effect of three different, widely used commercial high-strength alloys on the corrosion and wear performance of the produced PEO coatings. Thus, the relevance and the significance of the influence of different alloy compositions on the integral wear and corrosion properties of the PEO coatings shall be clarified.
