Coatings for magnetic materials, such as rare earth magnets, are described. The coatings are designed to reduce or prevent the release of one or both of nickel and cobalt from the coatings or from the underlying magnetic material. The coatings are designed to resist corrosion and release of nickel and cobalt when exposed to moist conditions. The coatings are also designed to be robust enough to withstand damage due to scratch forces. In some embodiments, the coatings include multiple layers of one or of metal and non-metal materials. The coated magnets are well suited for use in the manufacture of wearable consumer products.

A waveguide for high efficiency transmission of high energy light useful in ablation procedures at predetermined bandwidths over predetermined distances comprising: an optical fiber core; a silanization agent; layered cladding surrounding the optical fiber core comprising: a first thin metal layer comprising at least two types of metals the first thin metal layer covalently bonded to the core and a second thin metal layer bonded to the second metal layer, and a catalyst component; wherein the silanization agent comprising organofunctional alkoxysilane molecule, such as 3-aminopropyltriethoxysilane (APTS), is a self supporting bridge between the surface of the optical fiber and the first metal layer; the first metal layer is uniformly chemisorbed onto the surface of the optical fiber by means of covalent SiOSi bonds with the optical fiber; further wherein the catalyst component derived from an activation solution for enhancing the layered cladding upon the optical fiber.

An apparatus and methods of improving the ion beam quality of a halogen-based source gas are disclosed. Unexpectedly, the introduction of a noble gas, such as argon or neon, to an ion source chamber may increase the percentage of desirable ion species, while decreasing the amount of contaminants and halogen-containing ions. This is especially beneficial in non-mass analyzed implanters, where all ions are implanted into the workpiece. In one embodiment, a first source gas, comprising a processing species and a halogen is introduced into a ion source chamber, a second source gas comprising a hydride, and a third source gas comprising a noble gas are also introduced. The combination of these three source gases produces an ion beam having a higher percentage of pure processing species ions than would occur if the third source gas were not used.

Non-cosmetic quality aluminum substrates are given a cosmetic finish by applying a PVD coating to the substrate. An enclosure for an electronic device can include an aluminum substrate including a 6000 series aluminum or 7000 series aluminum, a PVD coating disposed on the substrate, and a protective underlayer disposed between the aluminum substrate and the PVD coating.
