Abstract

The invention provides a preparation process of chemical plating Ni-P-PTFE-SiC composite plating layers. The preparation process comprises the following steps: (1) the pretreatment of carbon steel samples comprises the steps of sand blasting, cleaning, deoiling, derusting, cleaning and hydrochloric acid activation; (2) PTFE emulsion is pretreated; (3) SiC particles are deoiled; (4) the SiC particles are activated; (5) the SiC particles are dispersed; (6) plating liquid C of 800 ml is prepared; PTFE dispersing liquid and SiC dispersing liquid are added in the plating liquid C; (7) sample piecesare put in the mixed plating liquid C for plating by 2 h, and then, are taken out; (8) the plated sample pieces are ultrasonically cleaned in hot water, and are taken out for airing; and (9) the thickness, the bonding force, the hardness, the friction coefficient and the wear rate of the sample pieces are tested. Compared with a Ni-P plating layer, a Ni-P-PTFE plating layer and a Ni-P-SiC platinglayer, the plating layer achieves more excellent wear resistance. The plating layer is compact and free of holes, achieves self-lubricating and wear resisting effects, and can effectively achieve thepurpose of surface wear resistance of carbon steel.

Description

technical field [0001] The invention relates to a preparation process of a functional coating on the surface of a metal material, in particular to a preparation process of an electroless Ni-P-PTFE-SiC composite coating on the surface of carbon steel. Background technique [0002] Material wear is one of the main forms of material failure. Material wear is usually the loss of material surface quality, resulting in material thickness reduction and strength and other properties that do not meet engineering requirements. How to improve material surface wear resistance and reduce the loss of material surface quality is the key factor to prevent material wear failure. Material surface modification can improve the wear resistance of materials without changing the material matrix. Electroless plating is an important method for surface modification of materials. Among them, the electroless Ni-P alloy coating has high corrosion resistance and is widely used in process production. H...
