Abstract

The invention relates to a high-strength WC-ZrO2-Si nano-coating material and a preparation method thereof. The nano-coating material comprises, by mass, 75.04% of WC, 11% of ZrO2, 13% of Si and 0.96% of trace elements, and the trace elements comprise Cr, Mn and B. The preparation method of the coating material comprises the following steps: carrying out a gas atomization process to prepare WC-ZrO2-Si nanospheres; and mixing the prepared nanospheres with Cr, Mn and B by adopting an activator protection process to prepare nanopowder. The nano-material has the advantages of uniform morphology, complete particle, good structure, good macroscopic performances, high hardness and good wear resistance, is better than traditional coating materials, and is a great improvement in comparison with traditional alloy materials.

Description

technical field [0001] The invention relates to the technical field of thermal spraying, specifically high-strength WC-ZrO 2 - Si nano coating material and preparation method thereof. Background technique [0002] Thermal spraying operation has fewer procedures, shorter construction time, high efficiency and more economical. With the improvement of thermal spraying application requirements and the expansion of the field, especially the progress of the spraying technology itself, such as the increasingly high-energy and sophisticated spraying equipment, the performance is gradually improved. The thermal spraying technology has achieved rapid development in the past ten years. Not only the application field is large In order to expand, and the technology has been developed from the early preparation of general protective coatings to the preparation of various functional coatings; from the maintenance of a single workpiece to the manufacture of a large number of products; from...
