Description
Technical Field
The invention belongs to the technical field of special steel preparation, and particularly relates to an anti-sticking wear-resistant composite steel plate and a preparation method thereof.
Background
With the continuous progress of the technology, more and more special steels with high performance are developed and prepared for different industries. The wear-resistant steel is one of special steels with the largest demand, and is widely applied to the industries of mining, metallurgy, power generation, construction, agriculture and the like. In practical application, when the wear-resistant steel plate is used for preparing excavating, loading, transporting and processing equipment such as excavator buckets, loading and unloading truck buckets and mineral processing machines, materials are adhered and accumulated on the machines due to certain viscosity of the applied materials, and the running efficiency of the machines is reduced.
At present, for special steel used for excavating, loading, transporting and processing equipment, the wear resistance and the impact resistance are mainly considered. The steel with wear resistance mainly comprises chromium alloy, and can be prepared by high-temperature cladding, surfacing, injection infiltration and other technologies.
Chinese patent CN 108060345A discloses a processing method for improving the wear resistance of a high-chromium cast iron alloy, which comprises the steps of material preparation, high-chromium cast iron alloy blank preparation, workpiece preparation, high-frequency induction cladding and heat preservation treatment. The high-chromium alloy with good wear resistance is prepared by a cladding method, manganese, vanadium, nickel, molybdenum and zinc are added, the distribution of chromium and manganese elements in the alloy is obviously improved by using a mixing agent, and the high-chromium cast iron alloy with good impact resistance and good wear resistance is obtained, but the surface of the high-chromium cast iron alloy is not specially treated, so that the high-chromium cast iron alloy does not have good anti-sticking performance.
Chinese patent CN 102212740A discloses a high-chromium cast iron containing VN and TiN powder, a preparation method of the cast iron and a wear-resistant part, wherein the VN and TiN powder is VN with the purity of 99.5% and TiN with the purity of 99.3%, the powder accounts for 2-4% of VN and 2-4% of TiN by weight of the high-chromium cast iron, and the high-chromium cast iron further comprises 3.1-3.9% of C, 18-22% of Cr, 0.5-1.0% of Si, 0.6-1.6% of Mo, 0.6-1.2% of Mn, 0.1-0.4% of Ni, 0.04-0.09% of V, 0.011-0.031% of S, 0.018-0.030% of P and the balance of a base material of iron. VN and TiV are added into molten high-chromium cast iron to improve the wear resistance of the molten high-chromium cast iron, and the molten high-chromium cast iron is used for preparing wear-resistant impeller head blades and is good in performance, but the surfaces of the molten high-chromium cast iron are smooth and are not subjected to anti-sticking treatment.
If the pure high-chromium alloy is used for preparing the steel plate, cracks are easily generated in the impact process in the application process, so that the performance is reduced. Chinese patent CN111702294A discloses a high-chromium alloy composite wear-resistant steel plate and a production process thereof, wherein the high-chromium alloy composite wear-resistant steel plate comprises: the substrate is made of steel and provided with an upper surface and a lower surface; the high-chromium alloy composite wear-resistant layer covers the upper surface of the substrate, the thickness of the substrate is 5-15cm, the thickness of the high-chromium alloy composite wear-resistant layer is 4-30cm, the steel is Q235 common carbon steel or Q345 common carbon steel or stainless steel, and the high-chromium alloy composite wear-resistant layer consists of non-metallic elements and metallic elements. This patent utilizes build-up welding technique to prepare high chromium alloy and steel complex wear-resisting clad steel plate, and its wearability and impact resistance can show and improve, nevertheless because the surface does not carry out antiseized processing, in the in-service use process, the surface can be stained with soil stone, influences the use.
The main methods for improving the anti-adhesion property of the metal material comprise: firstly, adding a smooth plating layer or coating on the surface of a material; second, the surface of the material is treated to form a unique structure. However, in the process of engineering application, the added coating or coating is easy to fall off due to frequent impact and friction, so that the anti-adhesion performance of the coating is reduced. Chinese patent CN 105665855A discloses a preparation method of a bionic super-hydrophobic and low-adhesion surface without modification of aluminum alloy, which adopts a bionics concept to extract the geometric texture and mathematical distribution relation of the surface of a plant leaf with super-hydrophobic characteristics, directly constructs multi-scale bionic geometric texture on the surface of the aluminum alloy without any chemical modification, is applied to the preparation technology of super-hydrophobic and low-adhesion of the surface of the aluminum alloy, and realizes the engineering bionic high-efficiency reproduction of the super-hydrophobic function of the plant leaf. According to the method, the nano-micro structure with the bionic hydrophobic structure is constructed on the surface of the aluminum alloy by utilizing an electric spark micro-nano wire cutting method, but the method is only suitable for metal materials with low hardness and cannot be applied to high-hardness steel alloy, and the formed nano-micro structure has a large surface friction coefficient and cannot achieve an anti-sticking effect.
