Problems solved by technology

Commonly used high-density heat sources for surface cladding include lasers, plasma arcs, focused beams, etc., which are characterized by high energy density and good quality of the strengthened surface, but the equipment is expensive and the operation is complicated
Although the non-melting electrode argon arc has low energy density and low cladding efficiency, its equipment is relatively light, cheap, and easy to operate, and it is easy to weld on the construction site, making the argon arc surface strengthening technology easy to popularize. be promoted

Abstract

An argon arc cladding material based on self-fused Fe-based alloy powder belongs to the technical field of material surfaces. The argon arc cladding material is characterized in that the cladding material comprises the following raw materials in percent by mass: 50-90% of self-fused Fe-based alloy powder, 5-15% of ferro-vanadium, 1-8% of ferro-molybdenum, 1-5% of graphite, 0-40% of WC and 1-3% of rare-earth alloy. The cladding material can be prepared into two forms: being arranged on the surface of a clean workpiece in a coating manner and flattened to form a coating with a thickness of 0.8-1.5mm; pressing into a film which is 0.8-1.5mm in thickness, 6-10mm in width and 50-100mm in length; air-drying at a room temperature for more than ten hours and then baking at a temperature of 120-200 DEC G for two hours for standby use. The argon arc cladding material has a low fusion point and is well formed and used for repairing the surfaces of steel workpieces and improving the hardness and the wear resistance of the surfaces. The surface hardness of a cladding layer reaches HRC51-62.

Description

Technical field: [0001] The invention belongs to the technical field of material surface, and provides a material for non-melting electrode argon arc surface cladding, which is prepared based on iron-based self-fluxing alloy powder, adding alloy elements and ceramic phases. Background technique [0002] With the development of modern industry, the performance requirements of mechanical products are getting higher and higher in the production process. The long-term stable operation of products under high parameters (such as high temperature, high pressure, high speed, etc.) Higher requirements are put forward for strength, wear resistance and corrosion resistance. All kinds of mechanical equipment, instruments and meters, metal parts in metallurgical parts, and various tools and molds are often damaged and invalidated from the surface during use. A large part of the reason for the damage is caused by surface wear. Therefore, as long as the surface of the part is strengthened...
