Abstract

The invention relates to an Fe-Co3O4-WC-Cu coating material and a preparing method thereof. The Fe-Co3O4-WC-Cu coating material comprises, by mass, 4 parts of Fe, 39-49 parts of Co3O4, 47-60 parts of WC, 1 part of Cu and 0.15-0.68 part of trace elements. The preparing method comprises the following steps that firstly, an Fe-Co3O4-WC-Cu nanometer ball is prepared through a dry type pulverizing method; and secondly, the nanometer ball prepared in the first step is mixed with ground C, Mo, B, Zn and Co through a surface active agent protection method to prepare mixed powder. The hardness of a coating can reach HRC45, the density of the coating can reach 8.75 g / cm<3>, the spraying thickness of the coating can reach 6 mm, the density of the coating is good and is 0.72, and the coating is suitable for plasma spraying, has certain hardness and anti-abrasion performance and is high in bonding strength and grabbing force.

Description

technical field [0001] The invention relates to the technical field of thermal spraying materials, specifically a kind of Fe-Co 3 o 4 -WC-Cu coating material and preparation method thereof. Background technique [0002] Thermal spraying technology is to atomize the ingredients into fine molten droplets or high-temperature particles under the action of high-speed airflow, and spray them on the surface of the processed workpiece at a high flying speed to form a firm covering layer, so that the surface of the workpiece can obtain different hardness and durability. Wear resistance, corrosion resistance, heat resistance, oxidation resistance, heat insulation, insulation, electrical conductivity, sealing, disinfection, anti-microwave radiation and other special physical and chemical properties. It can repair the old and reuse the waste in equipment maintenance, and bring the scrapped parts back to life; it can also carry out strengthening and pre-protection in the manufacture of...
