It is further used as preferred embodiment, the opening shape of one end of the function cover is square or rectangular,
It is the situation of plane suitable for the position of repairing with prosthetic device.
Be further used as preferred embodiment, the surface of the function cover and catheter be provided with heat-barrier material or every
Hot coating, is conducive to keeping the reaction temperature in high temperature plating implementation process.
It is further used as preferred embodiment, the function cover and catheter use stainless steel or polytetrafluoroethylene (PTFE) material
Material, can be also made of the material of other inertia and difficult plating.
Meanwhile, function cover also can be used to coordinate the different surfaces shape of device to be repaired using other shapes.
With reference to the explanation of above-mentioned implementation method, a specific implementation step of the present utility model is as follows：
a）Surface dressing：To can with conventional immersion plating to workpiece or prepare the workpiece material implement chemical plating workpiece
Surface to be processed polished, polished, degreasing or pickling processes；
b）Plating front activating：To through step a）Treated workpiece surface carries out activation process；
c）Coating plating：By the high temeperature chemistry plating plating solution place of coating at room temperature through step b）Treated workpiece table
Face, the preparation of coating is completed by the fabricated in situ and coating of coating material；The high temeperature chemistry plates the temperature T >=Topt of plating solution
+ 10 DEG C, when wherein Topt is the plating solution to identical workpiece or prepares the material of the workpiece and implement chemical plating with conventional immersion plating
Corresponding optimal plating temperature.
It is necessary condition that what any electroless deposition reacted is smoothed out with the activated energy barrier for overcoming correlated response.Change
Bath system activation energy is most economical, one of most effective way is regulation and control bath temperature.With the normal of industrial actual application value
Rule chemical plating immersion plating technology, its optimal plating temperature is typically not less than 75 DEG C.If workpiece is not preheated etc. special before plating
Treatment, i.e., in normal temperature or room temperature, be then inevitably present the obvious temperature difference between workpiece/plating solution.When plating is coated with, due to plating
Liquid accumulates big with the contact area of surrounding room temperature air much smaller than conventional immersion plating, and plating solution with the ratio between workpiece surface product, therefore
After plating solution coats workpiece surface, obvious temperature-fall period certainly will be experienced.To ensure that plating solution will not after workpiece surface is contacted
Because effects of reduced temperature and loss of activity, this technology takes the countermeasure for preheating plating solution before plating is coated with.It is optimal to obtain
Plating effect, on the premise of bath stability is ensured, bath temperature is preferably controlled in than the plating solution to identical workpiece or its system
When standby material is with conventional immersion plating implementation chemical plating in the range of at least 10 DEG C high of corresponding optimal plating temperature.Otherwise, chemistry
Plating plating speed will be difficult to meet the need of practicality, or electroless plating reaction cannot smoothly be entered at all because the extraneous activation energy for providing is not enough
OK.Chemical plating bath used by coating plating can buy with the autogamy of any known or secret formula or directly commercially produced product.
The value level of plating other conditions such as specific process parameter such as plating solution coating speed, frequency and number of times is coated with, is then led depending on workpiece
Depending on the specific requirements such as hot property, electroplate liquid formulation, coating species, plating speed, Coating and its thickness.Coating plating terminates
Afterwards, the treatment such as workpiece is overall or its plating is locally preferably cleaned, dried, the plating solution of workpiece surface is remained in remove, and is wrapped
Running water and/or distilled water, deionized water scouring/drip washing are included, hot blast or compressed air are dried up, or effumability organic solvent is such as
Ethanol, acetone etc. dry after cleaning.To meet practical application needs, can also further be passivated, the treatment such as dehydrogenation.
It is process object with the 20# steel plates of size 250mm × 300mm × 2.5mm, first to its center 50mm × 50mm's
One surface region carries out preliminary grinding with hand-held emery wheel, then is polished successively so that 240-1000# silicon carbide papers are from coarse to fine.With absorbent cotton
Running water being dipped successively and distilled water being cleaned, dipping absolute ethyl alcohol with gauze after hot blast drying is cleaned, and is dried.With hair
The uniform brushing of hydrochloric acid solution that brush dips 7% is activated in preplating region, is blotted activating solution with filter paper after 60sec, is now selected
It is completely embedded with catheter with the function cover that opening shape is square and appropriate openings size, and will be in advance preheated to 95 DEG C
Chemical plating bath（Ju Ti Pei Fang and technological condition are shown in Table, when use conventional immersion plating with the plating solution to 20# steel at
During reason, optimal plating temperature is 85 DEG C）Injected inside the device by the opening closed on catheter, while hand-held catheter
And apply certain pressure and avoid plating solution from leaking outside, a large amount of bubbles can be produced after the several seconds, plating process is smoothed out, to prevent
Device air pressure inside is excessive to cause plating solution to leak outside, and can now open the opening closed on catheter is used to be vented, and treats that gassing shows
During as substantially weakening, then plating solution and the new plating solution of injection can be extracted out by above-mentioned opening.As above after circulate operation 60min, to filter
Paper blots the residual solution of specimen surface, and is cleaned with running water and distilled water successively, dries up.Result naked eyes are visible one layer
Light, uniform, fine and close silvery white coating.Power is combined to coating with cross-hatching to detect, it is found that coating/matrix is combined tight
It is close, without any peeling, obscission.Porosity test is carried out with the 10g/L potassium ferricyanides, 20g/L sodium chloride solutions, coating is found
It is fine and close.Droplet test is carried out with 50ml/L sulfuric acid, 3.5% sodium chloride and 100g/L sodium hydroxide solutions respectively, in 2h coating without appoint
What changes, and illustrates that corrosion resistance of coating is excellent.
Above is preferable implementation of the present utility model is illustrated, but the utility model is created and is not limited to institute
State embodiment, those of ordinary skill in the art can also make a variety of etc. on the premise of without prejudice to the utility model spirit
With conversion or replacement, these equivalent deformations or replacement are all contained in the application claim limited range.
