Spray Coatings

Abstract High-temperature corrosion of critical components such as water walls and superheater tubes in biomass/waste-fired boilers is a major challenge. A dense and defect-free thermal spray coating has been shown to be promising to achieve a high electrical/thermal efficiency in power plants. The field of thermal spraying and quality of coatings have been progressively evolving; therefore, a critical assessment of our understanding of the efficacy of coatings in increasingly aggressive operating environments of the power plants can be highly educative. The effects of composition and microstructure on high-temperature corrosion behavior of the coatings were discussed in the first part of the review. The present paper that is the second part of the review covers the emerging research field of performance assessment of thermal spray coatings in harsh corrosion-prone environments and provides a comprehensive overview of the underlying high-temperature corrosion mechanisms that lead to the damage of exposed coatings. The application of contemporary analytical methods for better understanding of the behavior of corrosion-resistant coatings is also discussed. A discussion based on an exhaustive review of the literature provides an unbiased commentary on the advanced accomplishments and some outstanding issues in the field that warrant further research. An assessment of the current status of the field, the gaps in the scientific understanding, and the research needs for the expansion of thermal spray coatings for high-temperature corrosion applications is also provided.

Insufficient formability can be a major issue in the manufacturing of complex parts, particularly in aluminum alloys that have less formability when compared to steel. The approach which is the subject of this work is to determine the technical feasibility of partial forming, followed by a fast heat treatment and then further deformation. Alloys for consideration would include both 5xxx and 6xxx alloys typically used on interior and exterior automotive panels. The heat treatment regimes used for 6xxx alloys did not affect the material structure, which was confirmed by microstructural analysis and comparison of mechanical properties before and after the heat treatment. Experiments on 5xxx alloys indicated relative improvement of 300% or more. Regimes of material deformation and heat treatment will be presented.
