Abstract

The invention relates to Fe-WC-B-Mo nanometer powder and a preparation method thereof. The Fe-WC-B-Mo nanometer powder comprises the following components in parts by mass: 5-35 parts of Fe, 45-65 parts of WC, 5-10 parts of B, 5-10 parts of Mo and 0.34-0.55 part of several other microelements. The preparation method comprises the following steps: (1) preparing Fe-WC-Mo nanospheres by adopting a gas atomization method; and (2), mixing the nanospheres prepared in step (1) with C, Mn, B, Co and Al by adopting a surfactant protection method, so as to prepare the Fe-WC-B-Mo nanometer powder. Various types of materials adopted by the Fe-WC-B-Mo nanometer powder are wide in source, low in price, high in hardness and good in abrasion-resisting property. The Fe-WC-B-Mo nanometer powder provided by the invention can be applied to mechanical parts which are used for operation at room temperature, thereby achieving size repairing of a hard coating and an abraded part of a sliding surface.

Description

technical field [0001] The invention relates to the technical field of thermal spraying materials, in particular to a Fe-WC-B-Mo nanometer powder and a preparation method thereof. Background technique [0002] Thermal spraying is to use some heat source (such as electric arc, plasma spray or combustion flame, etc.) to heat powdery or filamentary metal or non-metallic materials to a molten or semi-molten state, and then spray them at a certain speed with the help of the flame itself or compressed air. It is a technique of depositing onto the pretreated substrate surface to form a surface coating with various functions. [0003] The materials used in traditional spraying technology have poor bonding strength, high porosity, and poor wear resistance. New thermal spraying materials need to make up for these defects. Using new processes, new methods, and new formulas to produce materials with high hardness, high wear resistance, high corrosion resistance, uniform microstructure,...
