摘要： A cutting implement including a metal substrate and a coating is provided. The coating has zirconium PVD (ZrCRTiNO), which provides protection against corrosion of the metal substrate. In some instances, the zirconium PVD provides protection from corrosion for at least 200 hours. A layer of titanium nitride (TiN) can be added to the coating to increase the hardness of the metal substrate. In such an embodiment, the layer of titanium nitride (TiN) is applied before the zirconium PVD (ZrCRTiNO). Titanium nitride (TiN) coated steel is 3 to 5 times harder than uncoated steel. Thus, a combination of titanium nitride (TiN) and zirconium PVD (ZrCRTiNO) as a coating on a metal substrate can increase the life of the metal substrate by providing increased hardness and anti-corrosive properties.

摘要： Shaded, zirconia ceramic materials are disclosed that are suitable for use in dental applications. Ceramic bodies are made from a zirconia-containing ceramic material and a coloring composition comprising a terbium (Tb)-containing component and a chromium (Cr)-containing component as a coloring agent. The pre-shaded ceramic body is machinable into a dental restoration either as a bisque body or sintered body. A pre-shaded machinable sintered ceramic body may obviate the need for further processing steps, such as shading or sintering, and may be suitable for use in chair-side machining applications, such as in a dentist's office, significantly reducing the time to create a custom finished product.

摘要： The present invention relates to method and a system of reducing chromium (VI) from a chromium bearing solution. The reduction of the chromium (VI) is achieved by contacting the chromium bearing solution which comprises chromium (VI) ions in an aqueous solution with iron fibers in an exchange mass under oxidation-reduction potential conditions at a pH of at least 2.5, with entry of iron ions into solution in the aqueous solution and reduction of the chromium (VI) ions to chromium (III) recovered in the exchange mass. A solution substantially free of chromium (VI) ions and total chromium is produced and discharged from the exchange mass.

摘要： The invention relates to a system and method for the substantially permanent biogeochemical stabilization of solids impacted with hexavalent chromium/Cr(VI), including chromite ore processing residue (“COPR”). The invention comprises a novel treatment method of adding amendment(s) to COPR or other chromate impacted solids for the purpose of (1) weathering COPR minerals (when present) to convert the minerals that control alkalinity of the COPR to non-alkaline forms and liberate incorporated hexavalent chromium (Cr(VI)) in the process; (2) providing a chemical reductant (ferrous iron) to rapidly and permanently reduce the available Cr(VI) to trivalent form (Cr(III)); and/or (3) supporting longer-term biogeochemical Cr(VI) reduction enhanced by recycling of the chemical reductant, ultimately rendering the material non-hazardous as measured by acceptable methods. Amendments include but are not limited to acids; sources of ferrous iron; fermentable organic carbon source(s); and/or a source of active anaerobic microbes.
