As a relatively novel sintering technique, spark plasma sintering (SPS) has been used extensively over the past decade to prepare a wide variety of materials, e.g., ceramics, composites, cermets, metals and alloys. Many applications of the SPS technique are the fabrication of nanostructured materials using nanosize powdered precursors as starting materials. This article provides a review of research...
A WC–Co–Cr coating was deposited by a high velocity oxy-fuel thermal spray (HVOF) onto a 1Cr18Ni9Ti stainless steel substrate to increase its cavitation erosion resistance. After the HVOF process, it was revealed that the amorphous phase, nanocrystalline grains (Co–Cr) and several kinds of carbides, including Co 3 W 3 C, Co 6 W 6 C, WC, Cr 23 C 6 , and...
