摘要： A composite powder product suitable for hardmetal cutting tools and wear resistance applications is described. The product comprises a hard particulate phase chosen from a range of metallic carbides, nitrides, carbonitrides and the like, onto which hard phase is deposited a coating of cobalt or nickel, or a mixture of cobalt and nickel. The hard particulate phase has a particle size between 0.1 and 10 μm, and preferably between 0.1 and 2 μm.

摘要： The present invention relates to coated powder, comprising a Ti-bearing core and a Ni-bearing coating, which can be used for the production of porous Ni—Ti articles by the self-propagating high temperature synthesis (SHS) method. The obtained articles are ideally suited for use in biomedical applications. According to the invention, a coated powder is used comprising a metallic Ti-bearing core and a metallic Ni-bearing coating, characterised by a Ni:Ti atomic ratio of more than 0.5, preferably between 0.9 and 1.1, and more preferably between 0.96 and 1.04. By using coated powders, local fluctuations in composition are limited and well under control. Milling of powders and the ensuing contamination risks are avoided. The sintered objects obtained using coated powders have a more homogeneous porosity than that using mixed Ni and Ti powders.
