As powerful magic comes creeping back, dangerous days are dawning… Criminal Investigation Division inspectors Janus Mikani and Celeste Ritsuko were lucky to make it out of their last mission alive. Since then, strange troubles have plagued the city of steam and shadows, apparently as a result of magic released during the CID inspectors’ desperate interruption of an ancient ritual. The fabric of the world has been unsettled, and the Council has assigned Mikani and Ritsuko to investigate. They soon discover that matters are worse than they imagined. Machines have developed minds of their own, cragger pirates are raiding the seas with relentless aggression, and mad elementals are running amok. As the chaos builds to a crescendo, Mikani and Ritsuko must fight a war on two fronts—and this time, they may not be able to turn the deadly tide…

Highly-reflective silver mirrors are widely used in optical applications. However, silver tarnishes and corrodes in the presence of common atmospheric pollutants, which degrades its reflectivity and optical performance. Various overcoat layers have been developed to protect silver from corrosion, though the mechanisms by which these protective layers improve mirror durability are not fully understood. Accelerated environmental exposure testing was used to investigate the corrosion behavior of protected silver mirrors prepared by plasma beam sputtering. The composition and layered nanostructure of the corrosion features on mirrors with different adhesion layer materials were analyzed. A small amount of nickel in the adhesion layer had a significant impact on adhesion at the silver-dielectric interface, and directly affected the corrosion dynamics. Additionally, lateral migration of silver, not just silver corrosion, was an important factor in the corrosion process. Better adhesion at all layer interfaces is necessary to improve mirror durability.

High-reflectivity silver mirrors are widely used in optical applications. However, silver tarnishes and corrodes in air, which degrades its reflectivity and optical performance. While various layer schemes have been developed to protect thin film silver mirrors from corrosion and degradation, the mechanisms by which these protective layers improve durability are not fully understood. Accelerated environmental exposure was utilized to investigate the effects of layer composition and nanostructure on the environmental durability and corrosion behavior of Gemini-style protected silver mirrors prepared by plasma beam sputtering. Mixed flowing gas exposures of mirrors with various NiCr- and Cr- based layers revealed that the mechanisms of corrosion and degradation depend largely on the composition of the layers adjacent to the silver. The corrosion process originates at defects in the dielectric protection layer and proceeds into the coating structure, laterally along various layer interfaces, only sometimes resulting in substantial silver corrosion. Mirrors with one Cr-based layer adjacent to the silver develop characteristic circular corrosion regions along the Ag-Cr interfaces, influenced by oxidation and chloridation of Ag and Cr, reduced adhesion due to dissolution, and stress-induced delamination. Mirrors with NiCr-based layers on either side of the silver develop characteristic corrosion nodules as the interfacial attack is limited but corrosive attack of nickel and silver is locally disruptive to the layered structure. Single flowing gas exposures showed that low concentrations of chlorine significantly influence the extent of corrosion. Investigations on reduced stress in the mirror layers revealed that while stress affects the corrosion kinetics, the composition of the layers has a larger influence on corrosion feature development and growth. The electrochemical behavior of the layers adjacent to the silver also substantially influences the corrosion process as moisture transports corrosive species into the coating. NiCr, NiCrNx, and freshly-deposited Cr are available to cathodically protect Ag, whereas CrNx is not. However, these materials may be easily passivated, making them less available to provide protection. The oxidation and chloridation of nickel in the NiCr-based layers affects the silver dissolution and redistribution process. A novel application of coulometric reduction showed that optical degradation in these mirrors requires very little corrosion product.

This paper reports on an evaluation and modification of polymeric glazings to protect silver mirrors. The mirrors were made using Corning 7809 glass as a substrate onto which a thin silver film is deposited. The modified polymeric films are then cast from solution onto the silver. The mirrors were characterized by measuring the hemispherical reflectance and the specular reflectance at 660 nm and selected acceptance angles (7.5 mrad or 3.5 mrad). The mirrors were exposed to environmental degradation using accelerated weathering devices and outdoor exposure. Empirical evidence has demonstrated that polymethylmethacrylate is a stable polymer in a terrestrial environment, but the polymer does not provide adequate protection for the silver reflector. The crucial role in degradation played by ultraviolet (uv) light is shown by several experimental results. It has been demonstrated that uv stabilizers added to the polymer improve the weatherability of mirrors. The relative effectiveness of different stabilizers will be discussed in terms of the weathering modes, retention of optical properties, and effectiveness of the additives. The process for silver deposition influences the reflectance of silver mirrors, and the optical properties depend on subtle relationships between the metallization and the dielectric (polymeric) films that are in contact with the silver.
