  • Patent number: 11859290
    Abstract: An example hydraulic system component of a machine includes a protective coating deposited by high velocity air fuel (HVAF) thermal spray, exhibiting high adhesion strengths and surface morphologies that promote lubricant adhesion and reduce the leakage of oil and/or hydraulic fluid from the hydraulic system. The coating may have surface roughness with RZ values less than 2 ?m and hardness of 1000 Vickers or greater. The HVAF coating may be thinner than conventional coatings with thicknesses less than 100 ?m. The HVAF coating may be deposited on a variety of steel components with adhesion strengths greater than those achieved by high velocity oxygen fuel (HVOF). The HVAF coating may be formed without time consuming roughening and/or post-grind operations, resulting in cost savings compared to conventional coatings.

  • Patent number: 11859384
    Abstract: A wall panel that has a reflective barrier of an aluminized biaxially-oriented polyethylene terephthalate (BPET) between an OSB panel, and an industrial grade paper (which is pressed to look like natural wood grain). The aluminized BPET can be integrated into the industrial paper to become one sheet. This wall panel could be applied to interior paneling, drywall or gypsum board, as desired. Another option is to sandwich the aluminized BPET between the industrial paper and the reflective barrier, a layer of self-sealing asphalt. This makes the wall panel waterproof and airtight and helps to keep intact the engineered wood integrity. The aluminized BPET could go between a layer of insulation or particle board and its laminate. The panel's BPET should have a flap of an inch or so on one side to help with air sealing. This creates a barrier between varying temperatures, and adds an R value, and helps keep a building cool.

  • Patent number: 10955594
    Abstract: The disclosure is directed to a highly reflective multiband mirror that is reflective in the VIS-NIR-SWIR-MWIR-LWIR bands, the mirror being a complete thin film stack that consists of a plurality of layers on a selected substrate. In order from substrate to the final layer, the mirror consists of (a) substrate, (b) barrier layer, (c) first interface layer, (d) a reflective layer, (e) a second interface layer, (f) tuning layer(s) and (g) a protective layer. In some embodiments the tuning layer and the protective layer are combined into a single layer using a single coating material. The multiband mirror is more durable than existing mirrors on light weight metal substrates, for example 6061-Al, designed for similar applications. In each of the five layer types methods and materials are used to process each layer so as to achieve the desired layer characteristics, which aid to enhancing the durability performance of the stack.

  • Patent number: 10927044
    Abstract: Disclosed is a method for fabricating a solid article from a boron carbide powder comprising boron carbide particles that are coated with a titanium compound. Further disclosed herein are the unique advantages of the combined use of titanium and graphite additives in the form of water soluble species to improve intimacy of mixing in the green state. The carbon facilitates sintering, whose concentration is then attenuated in the process of forming very hard, finely dispersed TiB2 phases. The further recognition of the merits of a narrow particle size distribution B4C powder and the use of sintering soak temperatures at the threshold of close porosity which achieve post-HIPed microstructures with average grain sizes approaching the original median particle size. The combination of interdependent factors has led to B4C-based articles of higher hardness than previously reported.
