Abstract

The invention provides a magnetic-fluid-coated textured surface lubricating substrate and a processing method of the magnetic-fluid-coated textured surface lubricating substrate and belongs to the field of machine manufacturing. For the problems that a hard coating is low in bonding strength and easily peeled off, active processing of the micro-texture composite morphology, coating and magnetic fluid lubricating is conducted on the surface mainly bearing the friction and wear of the substrate material. The processing method comprises the steps that texturing processing is conducted on the surface of the substrate through a laser processing technology, the hard coating serves as a hard support layer, texturing processing is conducted on the surface of the magnetic hard surface through the laser processing technology, a magnetic film is deposited in the microstructure through an electro-deposition technology, magnetizing is conducted, and finally the texturing surface is coated with themagnetic fluid as a lubricating phase. By the adoption of the magnetic-fluid-coated textured surface lubricating substrate and the processing method, the service life of the substrate is prolonged, the wear to the material is reduced, and the bonding strength of the coating is enhanced.

Description

technical field [0001] The invention belongs to the technical field of mechanical manufacturing, and in particular relates to a magnetic fluid lubricating a substrate on the surface of a textured and magnetized hard coating and a processing method thereof. Background technique [0002] Wear, corrosion and lubricity properties of metal surfaces are critical. Coating technology is widely used due to its significant protective effect. At present, physical or chemical vapor deposition methods are usually used to prepare hard coatings on the surface of metal materials to improve the hardness and wear resistance of the surface. However, while the hard coating brings high hardness, there are many disadvantages, such as the hard coating is brittle, easy to fall off, and causes serious scratches and wear to the surface of other workpieces. [0003] Magnetic fluid is a new type of functional material, which has both the fluidity of liquid and the magnetism of solid magnetic materi...
