Abstract: Welding rods and associated cladded articles are described herein. Briefly, a welding rod comprises a hard particle component dispersed in a nickel-based alloy matrix or cobalt-based alloy matrix, the hard particle component comprising tungsten carbide particles having an average size of less than 45 μm, and the nickel-based alloy matrix or the cobalt-based alloy matrix comprising at least one metal carbide forming element.

Abstract: A powder feeder system includes multiple electro-mechanical powder feeders structured for conveying powder compositions to a mixing hopper. A programmable logic control (PLC) can be incorporated into the multiple feeder system. The PLC can be programmed for determining a real-time powder flow rates for the powder feeders, receiving recipe data input related to creating a resultant coating composition, comparing powder composition flow rate data to the recipe data, and adjusting the operational aspects of motors and metering wheels associated with the multiple powder feeders in response to comparing the powder composition flow rate data to the recipe data. In various applications, the powder feeder system can be a subsystem of a thermal spray system configured for hardfacing and coating work pieces such as drill bits, road mills, shafts, mining tools, and/or stabilizers.

Abstract: In one aspect, articles are described herein comprising wear-resistant claddings. An article described herein, in some embodiments, comprises a metallic substrate and a cladding adhered to the substrate, the cladding including a metal matrix composite layer comprising at least one hard particle tile having a pore structure infiltrated with matrix metal or matrix alloy. Infiltration of the pore structure of the hard particle tile by the matrix metal or alloy can render the tile fully dense or substantially fully dense.
