Abstract
The invention relates to a WC-Co-Fe-Ni nanometer material and a preparation method thereof. The WC-Co-Fe-Ni nanometer material is prepared from, by mass, 20-45 parts of Ni60A, 45-55 parts of NiO2, 0.5-2 parts of Al2O3, and 1-2 parts of microelements. The preparation method comprises the following steps that 1, WC-Co-Fe-Ni nanospheres are prepared through a dry smashing method; 2, the prepared nanospheres prepared in the step 1 are mixed with C, Cr, Si and Zn through a surfactant protective method to prepare mixed powder. The wear resistance and hardness of a coating are improved, the toughness and combination degree of the coating are high, the stacking thickness of the coating is greatly improved, the coating with the thickness of 2 mm can be prepared, the material is better than a traditional coating material, and a great improvement is achieved compared with a traditional alloy material.
Description
technical field [0001] The invention relates to the technical field of thermal spraying materials, in particular to a WC-Co-Fe-Ni nanometer material and a 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] There are many kinds of thermal spraying materials. Different materials and different proportions are required under different application requirements. The common defects of existing materials are insufficient spraying hardness and poor wear resistance, which cannot effectively prolong the service life of parts and do not give full play to thermal spraying te...
