中国古代青铜器表面鎏镀技术（二）

3鎏镀与鎏焊 3．1鎏镀工艺 鎏镀富锡铜时鎏镀件置于炉中不免相互紧靠,甚至上下叠放。若镀件之间不放置范板相隔,加热去汞时不免会有镀液流淌而导致上下两鎏镀件焊在一起。如果说商代早中期就有了鎏镀富锡铜的青铜器,则最晚在商代晚期已有少数鎏焊件。考古学者认为,两周时期青铜器已采用铜焊工艺。     

Leistungsfähige Spiegel für solarthermische Kraftwerke

High efficient mirrors for Concentrating Solar Power plants Mirrors are an essential component of CSP plants. Wet chemically coated silver mirrors supplied by Flabeg GmbH achieve an average specular and solar weighted reflectivity of 94.4%. Almost 30 years of field experience prove the durability of the coating. First surface mirrors could provide higher reflectivity, but so far either the necessary durability is not met or the costs are not competitive. Another approach to increase reflectivity is to equip the mirror with an antisoiling coating. This type of mirror is currently under field testing, showing already promising results. New paint systems for silvered mirrors will expand the locations for power plants to the shore or into tropical regions.

Microscopic surface structure of C/SiC composite mirrors for space cryogenic telescopes

We report on the microscopic surface structure of carbon-fiber-reinforced silicon carbide (C/SiC) composite mirrors that have been improved for the Space Infrared Telescope for Cosmology and Astrophysics (SPICA) and other cooled telescopes. The C/SiC composite consists of carbon fiber, silicon carbide, and residual silicon. Specific microscopic structures are found on the surface of the bare C/SiC mirrors after polishing. These structures are considered to be caused by the different hardness of those materials. The roughness obtained for the bare mirrors is 20 nm rms for flat surfaces and 100 nm rms for curved surfaces. It was confirmed that a SiSiC slurry coating is effective in reducing the roughness to 2 nm rms. The scattering properties of the mirrors were measured at room temperature and also at 95 K. No significant change was found in the scattering properties through cooling, which suggests that the microscopic surface structure is stable with changes in temperature down to cryogenic values. The C/SiC mirror with the SiSiC slurry coating is a promising candidate for the SPICA telescope.     

Corrosion characterization of durable silver coatings by electrochemical impedance spectroscopy and accelerated environmental testing

Highly reflective front-surface silver mirrors are needed for many optical applications. While various protective dielectric coating schemes have been developed, the long-term durability of Ag mirrors is still of great concern in the optics community for a variety of applications under harsh environments. The corrosion protection behavior of a SiNx-coated silver-mirror coating scheme was tested with electrochemical impedance spectroscopy (EIS) and accelerated environmental testing, including humidity and salt fog tests. The EIS data obtained were fitted with different equivalent circuit models. The results suggested that the 100A thick SiNx coating produced by rf magnetron sputtering was porous and acted as a leaky capacitor on the Ag film, whereas the addition of a NiCrNx interlayer as thin as 3A between SiNx and Ag films resulted in a much denser SiNx coating with a low-frequency impedance value of 2 orders of magnitude higher than that without the interlayer. Humidity and salt fog testing of different silver coatings showed similar results. The 100A SiNx/3A-NiCrNx/Ag coating exhibited excellent corrosion resistance against the corrosive environments used in this study.

Wolter type I x-ray focusing mirror using multilayer coatings

A multilayer coating is a useful addition to a mirror in the x-ray region and has been applied to normal incidence mirrors used with soft x rays. When a multilayer coating is used on grazing incidence optics, higher performance can be achieved than without it. Cr/Sc multilayers coated on a Wolter type I mirror substrate for a soft x-ray microscope are considered. The reflectivity and effective solid angle are calculated for Wolter type I mirrors with uniform and laterally graded multilayer coatings. The laterally graded multilayer mirror showed superior x-ray performance, and the multilayer tolerances were relaxed. This multilayer mirror could be especially useful in the soft x-ray microscope intended for biological applications.
