Abstract

The present invention relates to a kind of Ni-Cr-B-Cu nanometer material and preparation method thereof, its component and the mass number of each component are that Ni accounts for 25-56 parts, Cr accounts for 24-32 parts, B accounts for 15-28 parts parts, Cu accounts for 10-15, and trace elements account for 0.5-2 parts; the preparation method comprises the following steps: (1) adopting the dry pulverization method to prepare Ni-Cr-B-Cu nanospheres; (2) making the prepared nano The ball adopts surfactant protection method to mix C, Ti, Fe, Zn, Al to make nano powder. The present invention has certain hardness and anti-abrasion performance, because material hardness has certain reduction, can obtain higher bonding strength, and cost is lower, can be used for coating surface material or bottom material, because of high bonding degree, coating The layer thickness can be up to 3 mm, and it has excellent resistance to abrasive wear.

Description

technical field [0001] The invention relates to the technical field of thermal spraying materials, in particular to a Ni-Cr-B-Cu nanometer material and a preparation method thereof. Background technique [0002] Thermal spraying refers to a series of processes in which fine and dispersed metallic or non-metallic coating materials are deposited on the surface of a prepared substrate in a molten or semi-molten state to form a spray deposition Floor. It uses some kind of heat source (such as electric arc, plasma spraying or combustion flame, etc.) to heat powdery or filamentary metal or non-metallic materials to a molten or semi-molten state, and then sprays them at a certain speed by means of the flame itself or compressed air. A technique of depositing a pretreated substrate surface to form a surface coating with various functions. Usually, energy is provided by fuel gas or electric arc. [0003] The application of thermal spraying technology is mainly limited by the devel...
