A method of depositing a relatively thin film of bioinert material onto a surgical implant substrate, such as a dental implant. Chemical vapor deposition (CVD) may be used to deposit a layer of tantalum and/or other biocompatible materials onto a solid substrate comprised of an implantable titanium alloy, forming a biofilm-resistant textured surface on the substrate while preserving the material properties and characteristics of the substrate, such as fatigue strength.

Economic oxidation and fatigue resistant metallic coating

A gamma prime nickel-base superalloy and components formed therefrom that exhibit improved high-temperature dwell capabilities, including creep and hold time fatigue crack growth behavior. A particular example of a component is a powder metallurgy turbine disk of a gas turbine engine. The gamma-prime nickel-base superalloy contains, by weight: 16.0 to 30.0% cobalt; 9.5 to 12.5% chromium; 4.0 to 6.0% tantalum; 2.0 to 4.0% aluminum; 2.0 to 3.4% titanium; 3.0 to 6.0% tungsten; 1.0 to 4.0% molybdenum; 1.5 to 3.5% niobium; up to 1.0% hafnium; 0.02 to 0.20% carbon; 0.01 to 0.05% boron; 0.02 to 0.10% zirconium; the balance essentially nickel and impurities. The superalloy has a W+Nb-Cr value of at least -6, is free of observable amounts of sigma and eta phases, and exhibits a time to 0.2% creep at 1300.degree. F. and 100 ksi of at least 1000 hours.

This invention relates to an optical lenses, which includes a lens substrate, a multi-layers film is set on one side of the lens substrate to block partial blue light and infrared light. The multi-layers film is formed by interactive stacking a plurality of layers of a low refractive index film (such as silicon dioxide film, the mix material film which is composed of silicon dioxide and alumina or the mix material film which is composed of silicon dioxide and silicon oxide) and a high refractive index film (such as zirconium dioxide film, trititanium pentoxide film, titanium dioxide film, tantalum pentoxide film or the mix material which is composed of zirconium dioxide and titanium dioxide), and each layer of film is used a specific thickness. So that, the optical lens can produce the effect of blocking partial blue light and infrared light without overly increased in color, allowing the user's eyes to keep cool due to partial infrared light blocking. Moreover, the optical lens can also reduce the user's eyes produce age related macular degeneration or cataract to achieve the effect of reduce eye fatigue and prolong vision view due to partial blue light blocking.

Coated gun barrels comprising a metallic coating on the inner surface or bore surface of the gun barrel are provided, the coating comprising a first metallic component, molybdenum and optionally titanium. The first metallic component may be tantalum (Ta), niobium (Nb), zirconium (Zr), rhenium (Re), hafnium (Hf), tungsten (W) or combinations thereof. The coated gun barrels can display improved fatigue, thermal resistance, corrosion resistance, erosion resistance, crack resistance and/or wear resistance as compared to uncoated gun barrels, conventionally coated gun barrels or gun barrels with inserts.
