Abstract
The invention relates to a method for electroplating on the surface of a silica optical fiber. In the method, an optical fiber on which Ni-P is chemically plated is taken as a cathode; a nickel anode is first cleaned by using sodium hydroxide with the concentration of 30 percent, is then neutralized by using sulfuric acid with the concentration of 10 percent and is finally cleaned by using distilled water; 1.5g of lanthanum oxide additive is added into every liter of conventional electroplating solution; and the electroplating solution is plated on the surface of the silica optical fiber at the temperature of 25 DEG C and the current density of 0.7A dm<-2>. In the method, the lanthanum oxide is added into the electroplating solution according to a certain proportion, so that the deposition rate and the current efficiency are improved.
Description
Technical field
The present invention relates to the method for silica fibre electroplating surface, particularly the method for silica fibre electroplating nickel on surface.
Background technology
The optical fiber bragg grating sensor that silica fibre is made is detected temperatures and strain and many physical quantitys and the chemical indirect measurement of measuring relevant with temperature and strain directly.Rare earth element has than thick atom radius and particular electrical minor structure and is having good physical and chemical performance, and the rare earth element of matters is added in the electroplate liquid, can effectively change silica fibre surface metal electroplating efficiency.But because problem such as its process complexity, lack a kind of effective way of not only having accelerated film forming efficiency but also having improved film forming characteristics in the present electro-plating method.
Summary of the invention
In order to solve above-mentioned drawback, a kind of method of silica fibre electroplating surface is characterised in that: will be negative electrode with the optical fiber of chemical Ni-P plating, nickel anode elder generation be cleaned with 30% sodium hydroxide, and with the neutralization of 10% sulfuric acid, distilled water is cleaned afterwards again; The traditional tile special plating solution adds 1.5g/L lanthanum trioxide additive, 25 degrees centigrade of temperature of electroplating solution, current density 0.7Adm
-2Carry out plating.
Wherein, the method for described silica fibre electroplating surface, lanthanum trioxide additive use dissolving with hydrochloric acid purity are 99.9% lanthanum trioxide acquisition.
Embodiment
Material choice:
Greater than 99%, sodium-chlor purity contains the alcohol amount greater than 59% greater than 99.5% sodium lauryl sulphate greater than 98.5% anhydrous sodium sulphate analytical pure for 99.9% purity lanthanum trioxide, six hydration nickel sulfate purity, and boric acid purity is greater than 99.5% chemical Ni-P plating silica fibre
To be negative electrode with the optical fiber of chemical Ni-P plating, nickel anode elder generation be cleaned with 30% sodium hydroxide, and with the neutralization of 10% sulfuric acid, distilled water is cleaned afterwards again; Traditional tile special plating solution (six hydration nickel sulfate 180g/L, anhydrous sodium sulphate 60g/L, sodium-chlor 9g/L, PH=5.2, sodium lauryl sulphate 0.07g/L, boric acid 32g/L) adds 1.5g/L lanthanum trioxide additive, 25 degrees centigrade of temperature of electroplating solution, current density 0.7Adm
-2Carry out plating.
Wherein, the method for described silica fibre electroplating surface, the lanthanum trioxide additive uses the lanthanum trioxide of 1mol/L dissolving with hydrochloric acid mass concentration 1.5g/L to obtain.
Close cross section pattern use scanning electron microscopic observation to electroplating the top layer, coating is formed with equipment such as energy spectrometer and plasma emission spectrometer and various conventional method of analysis and is measured, discovery is electroplated with the nickel plating that doping lanthanum oxide additive not carries out and is compared, the present invention has improved nickel deposition speed (bringing up to 15.2 microns/hour by 14.2 microns/hour) and current efficiency, improved the nickel dam quality, density, microhardness is improved, average grain size, resistivity and wetting time are respectively by 12 microns, 27 micro-ohms centimetre and 5-6 reduce to 1.5 microns second, 23 micro-ohms centimetre and 2-3 second.
The invention is not restricted to the foregoing description; in design scope of the present invention; the description of book according to the above description, those of ordinary skill in the art also can make some conspicuous changes, but these changes all should fall within the protection domain of claim of the present invention.
