Steam oxidation behavior of Y-bearing cladding tube with aluminizing coating

A study of oxidation behavior of AZ91D alloy with YSZ coating using EIS

Oxidation behavior of AZ91D magnesium alloy with 3YSZ coating and aluminum interlayer was studied in air at 250 °C using electrochemical impedance spectroscopy EIS, scanning electron microscopy SEM, and X-ray diffraction XRD. The oxidation process was carried out in various duration times from 1 to 10 h. A three-electrode electrochemical cell was employed for all the EIS measurements. Also, to ...

Chromizing-aluminizing and Chromizing-siliconizing Coating of a Ferritic Steel

Microscopic Analysis and Electrochemical Behavior of Fe-Based Coating Produced by Laser Cladding

The effect of laser cladding on the surface microstructure and corrosion properties of coated/uncoated specimens were investigated. Fe-based alloy coating was produced on 35CrMo steel by laser cladding. The phase composition, microstructure, interface element distribution, microhardness and corrosion resistance of the cladding coating were measured. The results show that the cladding layer is m...

Oxidation and Electrical Behavior of Crofer 22APU Steel with the Co/Y2O3 Coating Produced by Direct Electroplating

Crofer 22 APU ferritic stainless steel has been evaluated as one of the favorable materials for utilization in Solid oxide fule cell (SOFC) interconnects. However, there are difficulties in utilizing these metallic interconnects, including the quick  decrease of their electrical conductivity and evaporation of Cr species. To overcome the above problems, the application of protective coatings ha...

Formation and Evaluation of Oxidation Behavior of Zirconia- Aluminide Coating on Nickel- Based Alloy

Practical applications of thermal barrier coatings with aluminide bond-coats are limited due to oxide scale spallation of the aluminide coating under applied thermal stresses. Considering the positive effects of oxygen-active elements or their oxides on the high temperature oxidation behavior, in this research zirconia was introduced into an aluminide coating. For this purpose, a Watts type bat...
