Embodiment Construction

[0066] The present invention will be further described below in conjunction with accompanying drawing:

[0067] figure 1 As shown, it is the process flow chart of laser cladding amorphous alloy coating on the surface of carbon steel plate, which should be operated in sequence according to the ratio of quantity.

[0068] The amount of chemical substances used in the preparation is determined according to the preset specifications, surface area, alloy layer depth, in grams, milliliters, centimeters 3 , mm is the unit of measurement.

[0069]Surface roughness of carbon steel plate in R a 2.5-5.0μm is appropriate to facilitate the adhesion and curing of the amorphous coating.

[0070] The amorphous coating is based on zirconium nickel aluminum copper according to the atomic number ratio Zr 63.8 Ni 17.2 al 11.4 Cu 7.6 Set, the preset powder thickness is 1mm.

[0071] Solid fusion on the surface of carbon steel plate is the most important process, which must be strictly carr...

Abstract

The invention relates to a method adopting laser cladding to form an amorphous alloy coating on the surface of carbon steel, and as the laser cladding method is adopted on a laser welder, the carbon steel plate is intensified. The technical scheme comprises the following steps: sand blasting the surface of the carbon steel; preparing mixed powder of zirconium, nickel, aluminum and copper; cladding the surface of the carbon steel by utilizing a laser beam, and enabling the laser beam to perform all-directional irradiation along a locus curve set by a computer program; forming the amorphous alloy coating after amorphous alloy powder is fused and cured on the surface of the carbon steel. By the adoption of the method, the surface hardness, abrasion resistance and corrosion resistance of the carbon steel are greatly improved; compared with the performances before treatment, the surface hardness of the carbon steel is increased by four times, the abrasion resistance is increased by four times, and the corrosion resistance is increased by 1000%; the intensifying method has the advantages of advanced process, detailed and accurate data, short technological process and simplicity in realization, and is safe, stable and reliable; the cladding coating is solid and not easy to drop off; the method is ideal in intensifying the surface of the carbon steel.

Description

technical field [0001] The invention relates to a method for laser cladding an amorphous alloy coating on the surface of carbon steel, and belongs to the technical field of coating metal on the surface of an amorphous alloy, laser cladding, and improving corrosion resistance. Background technique [0002] Carbon steel is the earliest and most used basic material in modern industry. All industrial countries in the world pay great attention to improving the quality of carbon steel, expanding its variety and scope of use, and are widely used in construction, bridges, railways, vehicles, ships and machinery manufacturing Industry, but also in the petrochemical industry, marine development, has also been widely used. [0003] Although carbon steel has many advantages, it is prone to battery reaction due to the activity of iron element, and the loose and porous structure of iron oxide makes its surface corrosion resistance poor, which greatly limits the application of carbon steel...
