Description

A kind of antistatic composite plating solution of scaffold

Technical field

The present invention relates to electroplate liquid technical field, the antistatic composite plating solution of more particularly, to a kind of scaffold.

Background technology

Plating, also known as metal electrodeposition technology, is to contain workpiece immersion in the solution being intended to deposited metal salt, and to workpiece Apply negative electrical charge, deposit the process of a layer of compact metal or alloy-layer with workpiece in surface of the work.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 insoluble solid particle is added to plating solution In, so that matrix metal and solid particle is co-deposited, form a kind of process for modifying surface of composite deposite.Nickel coating because It has excellent corrosion resistance, wearability and thickness of coating uniform the features such as, obtain at aspects such as aviation, automobile, electronics, chemical industry Apply to extensive.However, nickel coating coefficient of friction is larger.And polytetrafluoroethylene (PTFE) is to be polymerized by tetrafluoroethylene monomer, performance Stable, in addition to there is splendid resistance to chemical corrosion, also there is heat-resisting, cold resistance well, and very little 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 preparing has significant antifriction effect.

《NI-PTFE composite plating process is studied》In one literary composition, author proposes by adding polytetrafluoroethylene (PTFE) breast in electroplate liquid Liquid and FC134 cationic surfactant, are 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 the 34% about of nickel coating, but due to PTFE matter is soft, after entering in coating, so that composite deposite is reduced compared with nickel coating hardness, wear extent increased simultaneously.So In some fields, this composite deposite can not meet demand.Rare earth element can significantly improve solia particle in functional composite material Content, hardness, the performance such as wearability and high temperature oxidation resistance, a series of in chromium plating, thermo-chemical treatment, conversion film etc. at present It is applied in process for treating surface.So the present invention improves the property such as hardness and the wearability of composite deposite by adding rare earth element Can, expand application.
