The application discloses an aluminum cover forming method and an aluminum cover and relates to the technical field of aluminum cover manufacturing. The aluminum cover forming method comprises the following steps: S1, placing an aluminum plate into an initial forming die, and forming a macro-domain large curved surface in the middle of the aluminum plate and an initial foot position with the same height as a required foot position on the circumferential edge of the aluminum plate through the extrusion force of a press machine and the initial forming die; S2, placing the aluminum plate preliminarily formed in S1 into a final forming die, and further forming the macro-domain large curved surface formed in the middle of the aluminum plate into a final shape at room temperature through the final forming extrusion pressure of the press machine, and flowing and filling the edge cavity of the final forming die to form an edge through the extrusion of the final forming die, and forming a final foot position shape through the extrusion of the initial foot position; and S3, opening the die to take out the formed aluminum cover. The production of the large-size foot position height aluminum cover can be realized at room temperature, the energy consumption is low, and the aluminum cover is simple and convenient to manufacture.

This invention provides a method for reducing friction and wear in a water-based lubricant based on magnetic field-controlled nanochains, belonging to the field of water-based lubricant technology. The invention utilizes magnetic Fe3O4 nanoparticles as raw materials and employs a silanization reaction to achieve magnetic field-assisted self-assembly of one-dimensional Fe3O4@SiO2 nanochains. These nanochains are then dispersed in deionized water or other basic lubricants to form a nanochain water-based lubricant. During lubrication, the one-dimensional nanochains are aligned perpendicular to the sliding direction using a magnetic field, achieving controllable orientation and forming a uniformly oriented rolling bearing structure on the contact area of ​​the friction pair. This significantly reduces the coefficient of friction and wear rate. The method is simple, uses environmentally friendly materials, and allows for real-time control of the lubrication state. It can be widely applied to friction reduction and wear resistance in mechanical transmissions, water-lubricated bearings, flexible device interface protection, and micro-precision moving parts.
