Abstract

The invention relates to a hard Co-TiO2-Mo coating material and a preparation method thereof. The hard Co-TiO2-Mo coating material comprises components, by mass, 74 to 86 parts of Co, 5 to 14 parts of TiO2, 6 parts of Mo, 1 part of Al2O3 and 0.08 to 0.66 part of trace elements, wherein the trace elements include C, Mn, Zr, Cu and Gr. The preparation method comprises preparing Co-TiO2-Mo nanospheres through gas atomization, and mixing the prepared nanospheres and C, Mn, Zr, Cu and Gr to obtain a nanometer powder through an activator protection method. Particles prepared according to the hard Co-TiO2-Mo coating material and the preparation method thereof are good in organization structure and macroscopic performance. The hardness of a Co-TiO2-Mo coating prepared according to the hard Co-TiO2-Mo coating material and the preparation method thereof can reach up to HRC47, so the hardness and the wear resistance of the coating are accredited in some degree, and the coating is high in bonding strength and grasping performance.

Description

technical field [0001] The invention relates to the technical field of thermal spraying, in particular to a hard Co-TiO 2 - Mo coating material and preparation method thereof. Background technique [0002] Thermal spraying is a metal surface processing method that atomizes the spraying material in the molten state on the surface of the part through a high-speed airflow to form a sprayed layer. 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 tech...
