Description
Technical Field
The invention relates to the technical field of material processing and metal laser cladding welding, in particular to a bionic high-entropy alloy structure wear-resistant layer on a titanium alloy surface and a preparation method and application thereof.
Background
With the development of the petroleum industry, wells with special working conditions such as deep wells, ultra-deep wells, wells with ultra-short curvature radius, large-displacement horizontal wells and the like are developed more and more, and higher requirements are put forward on petroleum drilling and production equipment, particularly drill rods. The drill rod has the functions of transmitting the torque of the drilling machine to the drill bit, transmitting drilling fluid, and being linked with the drill bit to ascend, descend and rotate. The drill rod bears complex bending and twisting composite stress, and particularly under special working conditions of deep wells, ultra-deep wells and the like, the stress of the drill rod is increased, and the fatigue fracture of the currently used alloy steel drill rod is aggravated. The method for solving the problem is to lighten the drill rod and reduce the composite stress condition of the drill rod, thereby realizing torque transmission more efficiently.
The titanium alloy has high strength, good corrosion resistance and high heat resistance, and is widely used for manufacturing structural components in the fields of aerospace, petrochemical industry and biomedicine. Therefore, titanium alloys are considered preferable for lightweight drill rods. The friction welding type all-titanium alloy drill rod has appeared in the market, namely, the drill rod pipe body and the joint are made of titanium alloy materials, and the pipe body and the joint are connected in a friction welding mode. However, the titanium alloy has low surface hardness (equivalent to alloy steel hardness, about 25-35 HRC) and poor wear resistance, and particularly, in the drilling and production process, the friction between the drill pipe wall and the casing pipe can cause the abrasion of the titanium alloy drill pipe joint, the outer diameter is reduced, the strength of the drill pipe joint is reduced, and degraded rejection occurs. At present, the universal means is to weld the wear-resistant belt on the titanium alloy drill rod joint, so as to prolong the service life of the drill rod.
The invention patent application with publication number CN 110756963A discloses a method for welding a wear-resistant belt of a titanium alloy drill rod and the titanium alloy drill rod, wherein consumable electrode gas shielded welding is adopted, a wear-resistant welding wire is overlaid on a titanium alloy joint, the surface hardness is improved to 50-60HRC, and the titanium alloy drill rod joint is effectively protected. The invention patent application with publication number CN 111577158A discloses a titanium alloy drill rod joint wear-resistant belt coating welding structure and method, wherein a layer of intermediate medium is added between a coating welding layer and a titanium alloy substrate by adopting a laser beam method, so that the bonding force between the coating welding layer and the substrate is effectively increased (wherein the coating welding layer welding method does not relate), the surface hardness of a drill rod can reach 57HRC overall, and the wear resistance of the drill rod joint is effectively increased. The invention patent application with publication number CN 111139466A discloses a titanium alloy petroleum drill pipe wear-resistant belt and a preparation method thereof, a particle reinforced titanium-based wear-resistant material layer is prepared on the surface of a titanium alloy matrix by adopting an ultra-high-speed laser cladding method, a material system is selected by mixing Ti6Al4V powder and B4C powder in proportion, the hardness of a drill pipe joint can reach HV720, and the drill pipe joint is effectively protected.
The existing method for adopting the wear-resistant welding layer of the drill rod joint comprises gas shielded welding and laser cladding, wherein a material system comprises a wear-resistant welding wire, titanium alloy powder and ceramic which are mixed, when friction and wear continuously occur, the wear is from the accumulative effect of a sliding system from the aspect of physical essence, and the defect of a single material system is that the sliding system is single, the sliding system moves all the time once started under the action of continuous wear external force, cracks are formed, and the sliding system falls off, and the single material system has no capability of resisting the continuous action of a blocking sliding system (namely pinning or blocking sliding movement), so that the wear-resistant service life of the drill rod joint is relatively short. Therefore, continuous innovation is needed in the aspect of the structure of the wear-resistant layer of the petroleum titanium alloy drill rod joint, and a large lifting space is still left.
