Abstract: A method of manufacturing a device includes thermally spraying tungsten carbine in feedstock that does not include Cobalt but that includes Nickel, Copper, or a Nickel-Copper alloy, the method improves the base coating toughness, anticorrosion, and antifouling properties for high load application in sea water and brackish water environments. Additionally, a Cobalt-free material lowers material costs and reduces the global demand of Cobalt. Providing a topcoat of a Silicon-doped DLC significantly reduces the topcoat brittleness of common DLC failures such as “egg shell” in high stress applications. Thus, high hardness, low friction applications may be tailored in high stress applications.

Abstract: Ag-free or low-Ag binder alloys are provided that can be used as binders for abrasive materials such as core drill bits. The alloys comprise, or consist of, Cu, Sn and Ni, with Cu preferably the plurality or majority component. Methods of manufacturing abrasive materials comprising the binder alloys, such as infiltration processes, are also disclosed.

Abstract: Design and fabrication processes and compositions for bulk metallic glass materials. Examples of bulk metallic glasses based on the described compositions may contain a high atomic percent of titanium or iron, which is alloyed with metalloid elements and refractory metals. The compositions can be designed using theoretical calculations of the liquidus temperature to have substantial amounts of refractory metals, while still maintaining a depressed liquidus temperature. The alloying elements are molybdenum, tungsten, chromium, boron, and carbon may be used. Some of the resulting alloys are ferromagnetic at room temperature, while others are non-ferromagnetic. These amorphous alloys have increased specific strengths and corrosion resistance compared to conventional high strength steels.

Abstract: A wear-resistant attachment for insertion in a wear-resistant assembly, the assembly comprising a base with at least one recess, the attachment comprising: a bottom part configured to be removably inserted into the recess; and a top part comprising a wear-resistant material, wherein the top part is wider than the bottom part in at least one dimension such that the top part covers a surface of the base beyond the at least one recess.

Abstract: Design and fabrication processes and compositions for iron-based bulk metallic glass materials or amorphous steels. Examples of bulk metallic glasses based on the described compositions may contain approximately 59 to 70 atomic percent of iron, which is alloyed with approximately 10 to 20 atomic percent of metalloid elements and approximately 10 to 25 atomic percent of refractory metals. The compositions can be designed using theoretical calculations of the liquidus temperature to have substantial amounts of refractory metals, while still maintaining a depressed liquidus temperature. The alloying elements are molybdenum, tungsten, chromium, boron, and carbon may be used. Some of the resulting alloys are ferromagnetic at room temperature, while others are non-ferromagnetic. These amorphous steels have increased specific strengths and corrosion resistance compared to conventional high strength steels.

Examples of bulk metallic glasses based on the described compositions may contain approximately 59 to 70 atomic percent of iron, which is allowed with approximately 10 to 20 atomic percent of metalloid elements and approximately 10 to 25 atomic percent of refractory metals. The amorphous steels may exhibit X-ray diffraction patterns as shown in FIG. 1.

The alloying elements are molybdenum, tungsten, chromium, boron, and carbon. Some of the alloys are ferromagnetic at room temperature, while others are non-ferromagnetic.
