Description
Technical Field
The invention belongs to the technical field of casting, and particularly relates to a surface alloying method for a wear-resistant steel casting.
Background
The alloy layer of the alloy layer can improve the wear resistance, heat resistance, corrosion resistance and other properties of the casting according to the characteristics of the alloy, thereby prolonging the service life of the casting. The alloying of casting surface has wide application range, and the performance of cast iron, steel, copper alloy, aluminum alloy, etc. may be improved with the said method. The surface alloying of the casting has the advantage of ensuring that the wear-resistant surface of the casting is made of wear-resistant materials and the bonding surface is metallurgical bonding.
In order to obtain an alloy layer on the surface of a casting, the prior art generally realizes alloying on the surface of the casting by adding water glass, resin binder and the like into an alloying coating or a paste coating block. For example, CN105834353A discloses a casting method of a highly wear-resistant cement mortar ball valve body, which comprises adding a proper amount of water, acrylic acid, ammonium persulfate and the like into polyvinyl alcohol, mixing and grinding with ferrovanadium powder and the like uniformly to form casting infiltration coating, uniformly covering the surface of a dried sand core, pouring cast steel metal liquid, and performing sand shakeout cleaning and heat treatment to obtain the highly wear-resistant cement mortar ball valve body; CN107414058A discloses a surface alloying method for a high-strength wear-resistant casting, which is to dope nano silicon carbide into high-carbon ferrochrome alloy powder by a spray doping method to obtain nano silicon carbide # high-carbon ferrochrome doped alloy powder, then mix and grind the nano silicon carbide # high-carbon ferrochrome doped alloy powder with borax and phenolic resin to obtain an alloy layer coating, coat the alloy layer coating on the surface of a casting mold and solidify the alloy layer coating, pour molten iron into the casting mold, and obtain the high-strength wear-resistant casting after cooling, sand removal and grinding; CN103406519A discloses a coating alloy powder for casting surface alloying and an alloying method, high-carbon ferrochrome, ferrochrome nitride, ferroboron, ferrovanadium and rare earth magnesium ferrosilicon are ground into 80-120 meshes by a ball mill, then zinc powder of 150 meshes and 250 meshes is added and stirred uniformly, then a proper amount of resin, sodium tetraborate and alcohol are added and stirred further, finally the mixture is coated on the surface of a casting mold, high-temperature molten metal is directly poured into the casting mold, and then the casting mold is opened and air cooled to obtain a wear-resistant alloy layer; CN1139157 discloses a casting surface alloying process, which comprises drawing a mold plate including a mold sample into a negative pressure, making a sealing film covered thereon closely contact with the mold plate, then coating a coating on the film of the mold sample corresponding to the specific surface of the casting having special or good comprehensive performance requirements, laying a reinforcing material thereon, then covering a thin paper with a certain number of pinholes on the reinforcing material, making a sand mold by vacuum molding, making the reinforcing material layer attached on the mold sample adsorbed on the sand mold, and finally making a sand box in a negative pressure state through box assembling, pouring and dropping to obtain the casting with alloyed surface. CN1066013 proposes a novel surface alloying process in which a tungsten carbide alloy powder is prepared as a surface material precast block by a high-pressure forming technology without using a binder, cheap 40Cr steel or austempered ductile iron is used as a base material, and a casting mold adopts technical measures such as local heat preservation and exhaust around the precast block; CN107774890B discloses a method for preparing a chrome-iron-containing coating for a cast-infiltration method, which comprises the steps of grinding ferrochrome by a dry method and a wet method, wherein the particle size of the ferrochrome reaches 8 mu m, and mixing a polyacrylic alcohol solvent as a binder with ferrochrome particles, so that the ferrochrome particles and molten steel have good wettability, and the ferrochrome particles are adsorbed on the surface of a mold for surface alloying. By comparison, the following disadvantages are obvious in the method: the casting surface alloying process is characterized in that water glass, resin binder and the like are added into an alloying coating or a paste coating block, the problems of poor metallurgical bonding quality between an alloy layer and base metal, air holes, slag inclusion and the like between an alloying layer and a body bonding part exist, the bonding strength of the surface alloying layer is influenced, and the performances such as the wear resistance of the alloy layer are influenced.
