Special Issue Information

Dear Colleagues,

Corrosion is a naturally occurring phenomenon with a costly and detrimental impact on many critical industries. The national costs of corrosion generally represent approximately 1–5% of the GNP. Hence, it is important to understand the corrosion mechanisms and try to protect structures from severe corrosion.

Corrosion phenomena are closely related to the crystalline structures of matrixes. For example, the corrosion rate of different grains varies with the symmetry of the exposed crystalline face. Meanwhile, the grain boundary could also be vulnerable to corrosive ions due to the irregular distribution of atoms. Thus, it is critical to understand the corrosion process of materials by analysing the crystalline structures on the surfaces of materials.

After corrosion, the substrates are usually covered with corrosion products. The properties of these products have a great impact on the following corrosion process of the matrix. A dense, stable, and crack-free corrosion product layer could protect the matrix from a corrosive environment, while loose and unstable corrosion products many promote the corrosion process. Hence, it is important to study the relationship between corrosion behaviours and the crystalline corrosion products.

To inhibit the corrosion of a substrate, one of the most effective methods is to cover the substrate with a coating. A protective coating should combine with the matrix tightly and be compact and stable under certain corrosive environments. Many protective coatings have crystalline structures. The size and arrangement of grains and phases in the coating could also affect the corrosion resistance of the coating.

This Special Issue, “Corrosion, Coatings and Crystals”, aims to publish novel findings which focus on the effect of the crystalline structure of the matrix and coatings on the properties of the substrate, especially the corrosion behaviour of the substrate. Meanwhile, studies related to the degradation or enhancement of the surface of crystalline structures are also preferred.

It is our pleasure to invite you to submit full papers, communications, and reviews related to “Corrosion, Coatings and Crystals”.

The deposition of a calcium oxalate layer on dolomite demonstrates potential application in stone culture heritage conservation. However, due to insufficient coverage and the presence of cracks, the film’s usefulness is restricted. In this investigation, we used a simple two-step procedure to create a cohesive and uncracked film. The findings show that the protective layer provides better coverage of the dolomite surface without causing cracks and significantly improves acid resistance. Furthermore, after the simple two-step treatment, the color and adhesive strength of dolomite substrates remained nearly unchanged. Full article

Etch pits could form on an exposed surface of a crystal when the crystal is exposed to an etching environment or chemicals. Due to different dissolution rates along various crystalline directions in a crystal, the dissolution process is anisotropic; hence, etch pits usually have a regular shape. Here, the morphology and origin of the regular-shaped etch pits are discussed firstly; then, factors which could affect the morphology and density of etch pits are shown; finally, the state of the art of etch pit technology and the utilization of etch pits is presented. Traditionally, etch pits are utilized to evaluate the dislocation density and some defect-related properties. Now, in the modern fabrication industries, the relationship between etch pits and defects has been utilized more skillfully. High-quality crystals can be fabricated by controlling dislocations revealed by etch pits. Meanwhile, with the as-revealed dislocation as the diffusion path of atoms, new crystals will emerge in corresponding etch pits. Full article
