A high-strength antifriction and wearable aluminum-manganese bronze alloy is prepared by using Mn, Al, Fe, Zn, Ce, Si, B and Cu as ingredients, and performing casting, hot forging or hot rolling machine-forming; the mass percent of all elements in the high-strength antifriction and wearable aluminum-manganese bronze alloy is 8-10 percent of Mn, 8-10 percent of Al, 1.5-2.5 percent of Fe, 1.5-2.5 percent of Zn, 0.4-0.8 percent of Ce, 0-3 percent of Si, 0-0.4 percent of B and the balance of Cu. The high-strength antifriction and wearable aluminum-manganese bronze alloy overcomes the defects that babbitt metal is low in fatigue strength, and poor in heat resistance, and the adhesion resistance, the compliance, the embedded hidden performance of a copper base alloy and an aluminium base alloy are easily improved in a bad lubrication environment, solves the traditional industry problem that toxic metal such as lead and cadmium causes environmental pollution easily, has relatively high mechanical strength and carrying capacity, is suitable for manufacturing ideal high-strength antifriction and wearable material of components of a friction motion pair under the complex working conditions, such as high speed, heavy load, high temperature and corrosive mediums in industries, such as machinery, metallurgy, energy and chemical engineering, and for example, is suitable for manufacturing a sliding bearing, a worm gear pair, a sliding block, a shaft sleeve, a transmission nut and other components.

The invention relates to a high-performance antifriction and antiwear manganese-aluminum-bronze alloy. According to the technical scheme adopted by the invention, the high-performance antifriction and antiwear manganese-aluminum-bronze alloy is prepared from Mn, Al, Fe, Zn, Ce and Cu by casting and hot forging or hot rolling. The elements of the high-performance antifriction and antiwear manganese-aluminum-bronze alloy comprise 5-10% by mass of Mn, 6-10% by mass of Al, 1.5-2.5% by mass of Fe, 1.5-2.5% by mass of Zn, 0.4-0.8% by mass of Ce and the balance of Cu. The high-performance antifriction and antiwear manganese-aluminum-bronze alloy provided by the invention can be used for overcoming the defects of low fatigue strength and poor heat resistance of babbitt and increase of seizure resistance, compliance resistance and embedment resistance of copper-based alloy and aluminum-based alloy in poor lubrication environment and solving the traditional problem in the field that toxic metals such as lead and cadmium can cause pollution to environment easily. In addition, the high-performance antifriction and antiwear manganese-aluminum-bronze alloy can function as the antifriction and antiwear material of all parts and components of a friction motion pair used in complex conditions of high speed, heavy duty, high temperature and corrosive media in the machinery industry, metallurgy industry, energy industry and chemical industry and can be used for preparing parts and components such as sliding bearings, worm gears, sliding blocks, shaft sleeves and driving nuts.

The invention discloses an aqueous epoxy adhering solid lubricant. The lubricant is composed of bi-component aqueous epoxy resins, a solid lubricant, a wear-resisting agent, a surface active agent, an antiseptic agent, an anti-sedimentation agent and water. The lubricant can be coated on the surfaces of processing workpieces such as stainless steel, carbon steel, alloy and the like. The lubricant is characterized in that water is adopted as a solvent, which has no pollution and no damage on bodies of painting constructors; and the coating has the advantages of good antifriction property and excellent physicochemical properties, and can replace an organic solvent type solid lubricant to be used on slide parts of multiple mechanical devices.
