Description

Ternary boride reinforced iron-based wear-resistant coating and preparation method thereof
Technical Field
The invention belongs to the field of plating of metal materials, and particularly relates to an iron-based wear-resistant coating and a preparation method thereof.

Particularly, when a large-size high-thickness (more than 3mm) friction part is prepared by laser cladding deposition, the critical problem that the laser forming of the high-performance friction part is restricted by cracks caused by stress and structure phase change stress is solved. Therefore, for laser additive manufacturing of high-wear-resistance iron-based alloy parts, a new alloy component system is formed by adding a reinforcing and toughening component starting from alloy component design, and a new method for regulating and controlling the structure and performance of laser additive manufacturing is researched.
The ternary boride has excellent performances of high hardness, high bending strength, low density, wear resistance, corrosion resistance and the like, and has the characteristics of thermal expansion coefficient close to that of a steel matrix and the like, and is an ideal coating material for the steel matrix. The iron-based alloy has wide sources and low price, and has good hardness and performance at the temperature of lower than 200 ℃, but the research of preparing the high-wear-resistance iron-based coating by adding the ternary boride into the iron-based alloy powder for cladding is rare.
The existing cladding technology mainly comprises the following steps: laser cladding, induction cladding, plasma cladding, vacuum cladding, overall heating remelting, flame cladding, surfacing and the like. However, the laser cladding equipment has high cost, the automatic control degree in the cladding process is low, the coating surface is uneven, the subsequent processing amount is large, and the coating is easy to crack and fall off; the plasma cladding coating alloy is easy to flow due to overheating or is seriously oxidized and burned, the cladding layer often has cracks, and the process requirement is high; vacuum cladding requires a vacuum environment, so that the actual operation difficulty is high and the cost is high; the integral heating remelting is integral heating, and has large heat influence on a matrix; the heat influence of flame cladding on a matrix is large, a coating is easy to oxidize when melted, and the influence of manual operation is large, the surface is easy to be uneven, and the efficiency is low; the surfacing material in China is characterized in that the ratio of manual welding rods is large, manual surfacing is troublesome and labor-consuming, the production efficiency is low, and the dilution rate of a matrix is large. The induction cladding technology has the advantages of small dilution rate to the matrix, low cost, high bonding strength of the coating, clean working environment and the like.
