| description | The invention discloses nanocarbide-enhanced tungsten-carbide-based composite powder with high erosion resistance and cracking resistance, a coating and a preparation method thereof. The nanocarbide-enhanced tungsten-carbide-based composite powder contains the following components: tungsten carbide (WC), metal binding agent and nanocarbide enhancing phase, wherein the nanocarbide enhancing phase is one or more of tantalum carbide (TaC), titanium carbide (TiC) and zirconium carbide (ZrC). The composite powder disclosed by the invention has the beneficial effects that the strength and the hardness of a metal binding phase can be effectively improved, and meanwhile the growth of crystal grains of the WC can be inhibited; the coating has the beneficial effects that the erosion resistance is improved by 50-200% compared with that of common tungsten-carbide-based metal ceramic coating, the toughness is also obviously improved, cracking can be almost avoided, meanwhile good high-temperature resistance, corrosion res |
