Abstract

The invention discloses a plating film forming solution of a nickel-based molybdenum disulfide wear-resistant composite film for laser cladding, and the application of the solution, and discloses a method for preparing a ceramic film on a metal surface. According to the technology formula, the plating film forming solution comprises the following components: 200-500 g / l of nickel sulfate (AR), 30-50 g / l of boric acid (AR), 10-15 g / l of sodium chloride (AR),1-2 g / l of gluside (AR), 0.01-0.1 g / l of sodium dodecyl sulfate (AR), 5-20 g / l of molybdenum disulfide (AR) and the balance of water; the condition for a technology for preparing the nickel-based molybdenum disulfide composite film is that the temperature is 40-50 DEG C, the pH is 4.0-5.0, the electric current density is 1-2 A / dm <3>, and under air, continuous stirring which meets the requirements of a plating technology is performed to obtain the nickel-based molybdenum disulfide composite film for laser cladding. The invention further discloses a method for preparing the wear-resistant composite film. According to the invention, the defect that performing laser cladding on the molybdenum disulfide can not be realized is overcome, so that a wear-resisting property of a laser-cladding layer is greatly improved.

Description

technical field [0001] The invention relates to the fields of surface treatment and laser cladding, in particular to an electroplating composite film layer. Specifically, it refers to an electroplating film-forming solution for a nickel-based molybdenum disulfide wear-resistant composite film layer for laser cladding and its application. Background technique [0002] Wear-resistant coating refers to a coating made of inorganic non-metallic wear-resistant materials on the surface of metal materials. Usually made by spraying, it has the characteristics of high hardness, good wear resistance, high bonding strength with metal materials, acid resistance, alkali resistance, and strong corrosion resistance. [0003] Molybdenum disulfide is an important solid lubricant, especially suitable for high temperature and high pressure. It has the characteristics of moisture-proof, waterproof, alkali-proof, acid-proof, etc., and can play a filling role. Due to the low friction coefficient...
