Abstract

The invention relates to a high-strength Co-TiO2-Mo nanocoating material and a preparation method thereof. The Co-TiO2-Mo nanocoating material comprises the following components in parts by mass: 39-70 parts of Co, 13-23 parts of TiO2, 15 parts of Mo, 1 part of Al2O3 and 0.21-0.73 part of trace elements, wherein the trace elements comprise W, Al, Cu, Zn and Mn. The preparation method comprises the following steps: preparing Co-TiO2-Mo nanospheres by adopting a gas atomization method; and then mixing the prepared nanospheres with W, Al, Cu, Zn and Mn to prepare nanopowder by adopting an active agent protection method. The high-strength Co-TiO2-Mo nanocoating material has the advantages of complete particles, relatively good tissue structure and relatively good macro-performance. A Co-TiO2-Mo nanocoating prepared from the Co-TiO2-Mo nanocoating material provided by the invention has the hardness of HRC40, and has certain hardness and wear resistance and relatively high bonding strength and grabbing force.

Description

technical field [0001] The invention relates to the technical field of thermal spraying, in particular to a high-strength Co-TiO 2 -Mo nano coating material and preparation method thereof. Background technique [0002] Thermal spraying is a high-strength metal surface processing method that sprays molten spraying materials on the surface of parts through high-speed airflow to form sprayed coatings. We call the special working surface "coating", and the working method of manufacturing the coating is called "thermal spraying", which is a general term for spraying and spraying welding with various heat sources. [0003] Thermal spraying technology has the following outstanding advantages: 1. The combination of surface engineering and various composite materials has obvious advantages in material design; 2. The chemical composition of materials can be easily adjusted; 3. It can dynamically form special structural properties 4. The combination of multiple materials and multiple...
