Compared with available technology, the present invention has simple and reliable technology process, and is favorable to obtaining homogeneous and stable antiwear coating.
Description
[technical field]
The invention belongs to technical field of surface, a kind of specifically nano silicon compound wear resistant coatings technology.
[technical background]
The research and development of scuff-resistant coating and application thereof are paid attention to by the people of mechanical engineering field always, and it is most important for the work-ing life of improving material how to obtain high performance scuff-resistant coating.The brush coating technology because have that equipment is simple, technology flexibly, the long-pending speed of plating is fast, the coating kind is many, the bonding strength advantages of higher of coating and body material, thereby the reparation, especially a puzzled embodiment repairing or the open-air repairing for big machinery that are widely used in component of machine more have outstanding practical value.Last century, the eighties began, people adopt the brush coating technology to obtain composite deposite, its principle is before brush plating plating a kind of or several insoluble solid particles to be added in the plating bath, make solia particle and metal ion codeposition, thereby and make its equably disperse in metal plating, form composite deposite.But because the solid particulate that adds mostly is micron order in the past, its performance can not satisfy the requirement of development in science and technology, so range of application is subjected to certain limitation.
Since nano material is born,, has added the more excellent composite deposite of nano material preparation performance and become possibility because its many Jie that are different from microcosmic and macroscopic material see characteristic.Nano material is meant by superfine crystal grain to be formed, and size is less than the solid material of 100nm.The nano-solid particle is joined in the common electrical brush plating liquid, and the nanometer brush lining that can obtain superior performance closes coating.Nano-composite plate can increase substantially the characteristics such as wear resistance, solidity to corrosion, high temperature oxidation resistance and heat conductivility of coating, therefore has wide application value in the Surface Engineering field.
[summary of the invention]
The objective of the invention is to design a kind of nano silicon compound wear resistant coatings technology, make the uniform and stable scuff-resistant coating of obtained performance, to satisfy the needs of most of wear-resisting spare part.
For achieving the above object, design a kind of nano silicon compound wear resistant coatings technology, comprise following processing step: working-surface pre-treatment, electricity are clean, the activation of 2# activation solution, the activation of 3# activation solution, the bottoming of special nickel, adopt the nano silicon electric brush plating liquor to carry out brush to be coated with composite deposite fully.Electricity needs voltage 12V when clean, adopts positive connection, and speed is 9m/min during brush plating, and the time is 40S.Need voltage 10V during the activation of 2# activation solution, adopt opposition method, speed is 9m/min during brush plating, and the time is 15S.Need voltage 14V during the activation of 3# activation solution, adopt opposition method, brush plating speed is 9m/min, and the time is 60S.Special nickel needs voltage 12V when feeling secure, and adopts positive connection, and brush plating speed is 9m/min, and the time is 120S.The brush lining needs voltage 12V when closing coating, adopt positive connection, and speed is 9m/min during brush plating, and the time is 600S.The preparation method of nanometer electric brush plating liquor is: the nanometer silicon dioxide particle that adds 5g/L in the fast nickel electric brush plating liquor of common spy, be of a size of 30nm, add the polymethyl acid amide of 0.3g/L and an amount of poly carboxylic acid again, carry out magnetic agitation 10min then, behind the ultrasonic again concussion 10min, obtain the nanometer electric brush plating liquor.
Compared with prior art, preparation technology of the present invention is simple and reliable, helps the uniform and stable scuff-resistant coating of obtained performance, can satisfy the needs of part wear-resisting spare part.
