Deposition of cast Mo2NiB2-Ni metal-matrix composite coating by combined centrifugal SHS

Abstract:

WC-Co metal matrix composites (MMCs) are widely used in manufacturing cutting tools and as a material of nozzles wear-resistant machine parts, guide rolls, seal rings, armour, and other functional applications. But relatively low corrosion resitance and electrical/thermal conductivity of these materials stimulates a search for new tungsten-less materials with a bunch of better service parameters. Among other hard materials, some complex transition metal borides such as Mo2NiB2 Mo2FeB2, etc seem most promising candidates of the above role. To date, such materials are fabricated by either high-temperature sintering followed by HIP processing or by SPS method. This work aimed at developing a new cost-effective process for fabricating cast Mo2NiB2-Ni; and Q the rection heat.
