This invention relates to an antimicrobial product containing silver-copper particles and its preparation method. The product includes a substrate and positively charged silver particles with a particle size of 15 μm to 50 μm, and a positively charged copper particle with a particle size of 10 μm to 50 μm, wherein the copper particle size ratio to the silver particle is 0.8 to 1.2. The silver particle, the copper particle and the substrate are combined by means of semi-fused sintering, wherein the ratio of the silver particle to the copper particle is 40:60 to 95:5. The sum of the substrate, the silver particles and the total particles of the copper particles is less than or equal to 10%.

A method for fabricating multi-layer ceramic broadband radome includes thermal-spraying layers of coating materials on the radome. The assembled structure exhibits tuned RF transparency response depending on the thickness and the dielectric constant of the deposited layers. Sub-micron thick ceramic layers, which are essential for broadband performance and hard to produce due to their fragile nature, can be deposited on big and complex objects by a fast and automated process.

To form, on a ceramic member or a metal member, a thermal spray ceramic coating film which achieves both the quality of a ceramic coating film and gas barrier property, and with which a composite oxide having a melting point lower than the ambient temperature will not form when used as a coating film on a ceramic member or a metal member constituting a glass article manufacturing apparatus. A ceramic coating film-provided member comprising a ceramic member or a metal member and a thermal spray ceramic coating film formed on at least a part of the surface of the ceramic member or the metal member, wherein the thermal spray ceramic coating film contains Al.sub.2O.sub.3 and 12CaO.7Al.sub.2O.sub.3, and the weight ratio of CaO to Al.sub.2O.sub.3 (CaO/Al.sub.2O.sub.3) is more than 0.11 to 0.50.

The invention relates to an abradable coating for a turbomachine, comprising a mineral compound having a Mohs hardness of 6 or less and a melting temperature of more than 450° C. or even 800° C., and a polymeric compound with a content of between 40% and 70% by volume.

This invention relates to a thin and texturized film that can be applied onto a non-smooth surface to improve hardness, corrosion resistance and wear resistance properties of the surface while maintaining the underlying profile of the non-smooth surface. An additive overlaying process can be employed to produce the thin and texturized film on the non-smooth surfaces without substantial alteration or degradation of the underlying surface texture or profile of the non-smooth surfaces so as to sufficiently preserve the underlying surface texture or profile. The thin and texturized film fully covers the non-smooth in a uniform manner and maintains the surface profile.
