Method for plating nickel on surfaces of ceramic particles

Abstract

The invention provides a method for plating nickel on surfaces of ceramic particles. The method comprises the following steps: fused alumina zirconia ceramic particles are polished by using an abrasive paper; and after a preset roughness is reached, the fused alumina zirconia ceramic particles are put in anhydrous alcohol, are oscillated and cleaned by using ultrasonic waves, are put in rougheningliquid for roughening after drying, are sensitized after cleaning and drying, are put in acetone solution after sensitization, are cleaned by using the ultrasonic waves, are put in activating liquidfor activation after drying, are put in chemical plating liquid for plating after cleaning and drying, and are flushed and dried after plating to obtain finished products. The method for plating nickel on the surfaces of the ceramic particles increases real surface areas of the fused alumina zirconia ceramic particles and nickel metal, so that the bonding strength between the ceramic particles andthe nickel metal is improved; the reaction efficiency is improved; the nickel plating time is shortened; and the surfaces of the fused alumina zirconia ceramic particles after plating reach the metalgloss, are uniform in nickel plating and excellent in corrosion resistance, and achieve a certain wear resistance.

Description

technical field [0001] The invention relates to the field of surface treatment of ceramic particles, in particular to a method for plating nickel on the surface of ceramic particles. Background technique [0002] As we all know, two objects that are in contact with each other or moving relative to each other will have friction on their surfaces. In general, friction is often accompanied by wear, and when the wear reaches a certain level, it will inevitably lead to the failure of various machines or parts. a great safety hazard. my country is also a big manufacturing country. In our country, departments such as metallurgy, mining, building materials, electric power, and coal use a lot of mining machinery, engineering machinery, and various crushing and grinding equipment. These equipment generally operate in harsh industrial environments. Under the circumstances, some parts will consume a large amount of metal every year due to the wear and tear of sand, ore, soil and other m...

Problems solved by technology

Due to the poor wettability of metal and ceramic particles, the interface bonding strength is low, if the ceramic particles are directly put into the liquid metal process, it is not conducive to the smooth progress of the interface reaction, and a good composite layer cannot be obtained.
