Problems solved by technology

However, these methods still have the following problems: the bonding strength between the coating and the substrate is not high, and there are many pores; the process is difficult to control, the process cost is high, and the pollution is serious. Therefore, in order to overcome the deficiencies in the prior art, A new wear-resistant coating on copper alloy surface was developed by vacuum cladding method

Abstract

The invention discloses a copper alloy surface wear-resistant coating prepared by using AgCuTi and a preparation method thereof. The coating comprises the following raw materials according to the mass fraction: 32-65% of Ag-Cu-Ti powder, 30-65% of WC-10Ni powder and Silicone resin binder 3~5%. The coating is a flexible fibrous technical material, not only has uniform and dense composition, but also the metal fibers in the coating form a crisscross three-dimensional spider web structure; it is compounded with the base material, not only has excellent matching, melting point, lubricity, Good caulking ability, excellent forming effect, high bonding strength, can effectively improve the wear resistance and hardness of the surface of the substrate material; at the same time, the metal cloth can be cut into various shapes, and has a strong ability to adapt to the substrate. The space between the coating and the substrate The position can be well controlled; in addition, the preparation method of the coating is simple, safe and environmentally friendly.

Description

technical field [0001] The invention relates to using AgCuTi to prepare a wear-resistant coating on the surface of a copper alloy and a preparation method thereof, belonging to the field of composite materials. Background technique [0002] The development of industrial modernization has higher and higher requirements on the surface performance of equipment parts, especially under the conditions of high speed, high temperature, high pressure, heavy load, corrosive medium, etc., the damage of parts materials often starts from the surface, such as wear, corrosion, High-temperature oxidation, etc., even those parts that fail due to fatigue fracture caused by torsional or bending loads, the fracture often starts from the surface with the highest stress, and gradually develops to the inside to cause the failure of the entire part, resulting in a reduction in the working efficiency of the mechanical device , Frequent maintenance and replacement of workpieces, reduced product quali...
