Problems solved by technology

The internal composition of the electrode used in the traditional welding method is relatively simple, the formed welding layer has low bonding strength, poor wear resistance and corrosion resistance, and can only fill the structural size of the shape defects of the parts. It cannot improve the performance of the parts. After the parts are reused for a period of time, there will still be serious structural defects, such as severe wear and surface cracks, which will affect the actual working performance of the parts

Abstract

The invention relates to a Co-Mn-Si-Fe nanometer welding layer for welding and a preparation method. The Co-Mn-Si-Fe nanometer welding layer for welding comprises the following components in percentage by mass: 46-63% of Co, 29-37% of Mn, 7-9% of Si, 7-9% of Fe, 2-3% of Al2O3, and 0.5-1.5% of additive. The additive is Ni60A. The method comprises the following steps: Co, Mn, Si, Fe and Al2O3 are prepared to nanometer balls by an atomization method; the nanometer balls are uniformly mixed with grinded Ni60A to prepare nanometer welding rods; and finally, the nanometer welding rods are welded on the surface of a part to form the nanometer welding layer. The prepared nanometer welding layer has such advantages as high bonding strength, wear resistance and good corrosion resistance, realizes the repairing of the part, improves the service performance of the part, and prolongs the service life of the part.

Description

technical field [0001] The invention relates to the technical field of submerged arc welding, in particular to a Co-Mn-Si-Fe nano welding layer for welding and a preparation method thereof. Background technique [0002] Welding is one of the important means of parts repair, which makes up for the shape defects of parts and makes the structural size of parts meet the needs of actual use. The internal composition of the electrode used in the traditional welding method is relatively simple, the formed welding layer has low bonding strength, poor wear resistance and corrosion resistance, and can only fill the structural size of the shape defects of the parts. The performance of the parts cannot be improved. After the parts are reused for a period of time, serious structural defects will still appear, such as severe wear and surface cracks, which will affect the actual working performance of the parts. Contents of the invention [0003] The technical problem to be solved by th...
