Abstract: A novel silver braze alloy material is provided which exhibits both a low melting temperature and excellent wettability when brazing components of an article, such as a tools that include a polycrystalline diamond compact. For example, the combination of these properties is beneficial in terms of cost (given the lower silver content) as well as for brazing a cutter to a drill bit body by forming a strong bond (via the high wettability property) and reducing potential damage to the drill bit during the brazing operation (via the low melting temperature property of the alloy).

Abstract: A thermal spray material feedstock is provided for “flash-carbide” coatings. Flash carbide coatings are thin, dense, and smooth thermal spray coatings that self-activate the substrate. Flash-carbide coatings form and peen the coating to impart compressive stress for good adhesion and corrosion resistance. To achieve this combination of properties and performance, a powder that includes fine, dense, and angular particles is used; however, this powder alone results in a poor deposition efficiency of typically less than 20%. The present disclosure mitigates the poor deposition efficiency of this powder alone by providing a composition having two or more different particles at a specific ratio to improve deposition efficiency with sufficient optimized stress and corrosion properties and, in some cases, an increase in coating performance.
