Description
Technical field
The present invention relates to electroplate liquid technical field, particularly relate to the scaffold composite plating solution that a kind of decorative effect is good.
Background technology
Electroplate also known as metal electrodeposition technology, be that workpiece is immersed in the solution containing slaine to be deposited, and to workpiece
Apply negative charge, in surface of the work one layer of metal compact with workpiece of deposition or the process of alloy-layer.That electroplates is basic
Principle is to make the metal ion in solution that reduction reaction to occur on solution and plating piece interface by various electric field actions, generates gold
Belong to atom and be deposited on metal surface formation coating.Composite deposite is by by adding insoluble solid particle to plating solution
In, make matrix metal co-deposit with solid particle, form a kind of process for modifying surface of composite deposite.Nickel coating because of
It has the features such as excellent corrosion resistance, wearability and thickness of coating is uniform, obtains at aspects such as aviation, automobile, electronics, chemical industry
To extensively application.But, nickel coating coefficient of friction is bigger.And politef is to be polymerized by tetrafluoroethylene monomer, performance
Stable, in addition to there is splendid resistance to chemical corrosion, also there is the most heat-resisting, tolerance to cold, and the least friction
Coefficient.By adding polytetrafluoroethylgranule granule in electroplate liquid, polytetrafluoroethylgranule granule is made to be distributed to along with the electro-deposition of nickel
In nickel coating, the composite deposite prepared has significant antifriction effect.
In " research of NI-PTFE composite plating process " literary composition, author proposes by adding politef breast in electroplate liquid
Liquid and FC134 cationic surfactant, be successfully prepared Ni/PTFE composite deposite, and test shows that coating surface is uniform, flat
Whole, in terms of tribological property, the coefficient of friction of composite deposite is 0.218, is only about the 34% of nickel coating, but due to
PTFE matter is soft, after entering in coating, makes composite deposite relatively nickel coating hardness reduce, and wear extent increased simultaneously.So
In some field, this composite deposite can not meet demand.Rare earth element can significantly improve solid particle in functional composite material
The performance such as content, hardness, wearability and high temperature oxidation resistance, a series of at chromium plating, thermo-chemical treatment, conversion film etc. at present
Process for treating surface is applied.So the present invention will add the property such as hardness and the wearability of rare earth element raising composite deposite
Can, expand application.
