Problems solved by technology

[0004] At present, the research on laser cladding amorphous alloy coating materials is mostly limited to the exploration of process parameters and performance characterization, and the actual promotion and application process is slow. The reason is that the generation of high amorphous content requires extremely high solidification cooling rate. However, the high residual stress caused by quenching and the difference in thermal expansion coefficient with the substrate can easily lead to cracking of the cladding layer, and the contradiction between the two relative properties of "high amorphous content" and "crack-free" has not been effectively resolved.
In order to solve the problem of cracks, methods such as increasing heat input, adding hard strengthening phases, and preheating substrates are currently used, but these methods are not conducive to the generation of amorphous phases and the increase of their content, and also bring high performance, high The disadvantages of cost, complex process, cumbersome process, and low production efficiency, this technology is still under scientific research

Abstract

The invention relates to a preparation method of an iron-based amorphous coating. According to the situations that a stainless steel plate is poor in wear resistance and short in service life, the iron-based amorphous coating is cladded on the surface of stainless steel, so that the surface hardness, wear resistance and amorphous content of the stainless steel plate are improved. The hardness of the iron-based amorphous coating obtained after laser remelting reaches 750 HV, and the amorphous content of the amorphous coating reaches 54%. Laser remelting can be used for repairing cracks, holes and unfused solid particles on the surface of the coating, so that the coating dilution rate is reduced, the coating quality is improved, and the amorphous ratio is improved.

Description

technical field [0001] The invention relates to a method for preparing an iron-based amorphous coating, which belongs to the technical field of preparation and application of the amorphous coating. Background technique [0002] In recent years, laser technology has developed rapidly. As a kind of surface modification technology, laser cladding uses a laser beam as a heat source to clad a layer of reinforcement phase material on the surface of the matrix material, thereby metallurgically combining the matrix material and the reinforcement phase material. Together, the service life of the material is greatly improved. Laser cladding technology has the advantages of high instantaneous heating temperature, fast cooling speed, small thermal impact on the workpiece, and high bonding strength between the cladding layer and the substrate. It has become a green and efficient intelligent manufacturing / remanufacturing technology with huge potential economic benefits. . [0003] Compa...
