摘要：

An alternative approach to prevent corrosion of cemented carbide coated carbon steel in wet corrosion environments was tested. Carbon steel substrates were coated with a thin film of electroless nickel and then HVOF (High-Velocity Oxygen Fuel) sprayed with cemented cabide. Reference specimens without electroless nickel were sprayed at the same time. The microhardness of the specimens was measured and the coating structure examined using optical microscopy and X-ray diffractometry (XRD). The bond between the layers and the base material was determined using a bend test.
