This paper discusses the machinability of a self-fluxing alloy applied by thermal-spraying to machine parts based on observations of the cutting force and the finished surface. Cutting of this material is difficult using carbide tools, but possible with cubic boron nitride (CBN) tools. A large cutting force was applied to the tangential component of the three component forces. The surface roughness was fine, the roughness curve was stabilized, and a result approaching a theoretical value was obtained. However, microprotrusions of Ni particles, cleavage and plasticized flow were seen on the cut cross section. The best tools for cutting this self-fluxing alloy were CBN tools with high CBN content and the oxidized bonding agents.
