The 5th step, thermal treatment.Composite deposite sample after the electroless plating is placed resistance furnace, be warmed up to 250～300 ℃ with stove, insulation 2h, take out the cooling back.
The above-mentioned composite deposite that obtains is carried out performance test and analyzes discovery, TiO in the coating 2Per-cent reach 3.49%, coating and high base strength reach peak value 8.68MPa, sample weight loss is little, wear resistance is 1.69 times of base material, wear resistance the best.The average corrosion rate of composite deposite is very low, and solidity to corrosion is 58.5 times of magnesium alloy substrate;
The composite deposite microstructure is observed, as shown in Figure 2, compound titanium dioxide granule comparatively uniformly on the cell structure in the composite deposite, it is the visible white point shown on Fig. 2, nano particle is described in deposition process, is captured, and coated by Ni, Cu, P by metal Ni, Cu, the P of codeposition, common deposited and then progressively forms composite deposite on matrix.In forming process, nano-TiO 2A part is embedded in Ni-Cu-P cellular structure surface, and a part is coated in the Ni-Cu-P matrix metal, is evenly distributed on the whole.
Composite deposite is carried out energy spectrum analysis, and as Fig. 3 a, Fig. 3 b, TiO appears in composite deposite in the time of 25.108 ° 2Distinctive diffraction peak.This explanation X ray can penetrate Ni-Cu-P coating and detect nano-TiO 2Particle has also confirmed TiO 2Particle is present in the composite deposite really.After thermal treatment, a lot of sharp-pointed peaks have appearred in coating, as stable phase Cu 3P, Ni 3Cu has wherein also appearred in the P peak 2The O phase, this is the oxidized feature that shows of surface metal element when thermal treatment.
The coating antibiotic rate is up to 99.7%, this be since composite deposite in except antiseptic elements such as copper, nickel element in action, the more important thing is nano-TiO 2Adding, owing to its anti-microbial property that receives the excellence that illumination produces makes the anti-microbial property of composite deposite reach comparatively ideal level.
TiO 2Produce hole-electron pair at the Shi Caihui that excites that is subjected to sunlight, this hole-electron pair continues to be stimulated and forms nontoxic hydroxyl radical free radical and oxonium ion, and these just have the strong oxidizing property energy, bacterial oxidation can be caused death TiO 2The anti-microbial effect that produces owing to exciting of light exactly.When not having illumination, it is breakdown that the contact reacts of copper, nickel makes the cytolemma of bacterium in the coating, makes bacterium death.TiO under the illumination cultivation 2It is stronger to play a role, and anti-microbial property is than the illumination condition allowance below nominal size under the unglazed cultivation.Carry out the antibacterial controlled trial of intestinal bacteria with quantitative method of scoring, its result is shown in Fig. 4 a, 4b, 4c, 4d.
By Fig. 4 a, 4b, 4c, 4d as can be seen: the sterilization effect of composite deposite is better than ternary alloy coating, with check sample contrast, the kill rank of bacterium is all had obvious effects.Fig. 4 d is the microscopic morphology of the white bacterium observed at the Lecia microscopically, and it is shaped as elongated rod shape, prove that process of the test is under aseptic condition to finish, and the bacterium appearance of other kinds is not arranged, and the microbiological contamination phenomenon does not promptly take place.After 24 hours, the fungistatic effect of coating is very obvious in illumination, can illustrate in the long more germicidal action of playing of the time of illumination just obvious more.
Embodiment 2:
Regulate the solution composition among the embodiment 1, all the other steps are identical, proceed the bacteriostasis rate test of chemical composite plating.Wherein solution composition is to contain in every liter of plating bath: nickel sulfate content 12g/L; Ortho phosphorous acid sodium content 11g/L; Citric acid content 27g/L; Ammonium bifluoride content 8g/L; Thiocarbamide 1.2mg; Sodium lauryl sulphate 0.05g/L; Copper sulfate content 0.08g/L, nano-TiO 26gL -1Test-results shows: composite deposite has excellent photocatalysis performance, with TiO 2The photocatalysis of powder is suitable, and this is TiO 2Powder has found a carrier, can increase the repeat usage of anti-microbial property, is the perfect adaptation of antimicrobial technology and electroless plating technology.In the contrast of different time, coating and bacterium antibacterial effect of a specified duration more duration of contact are remarkable more.
Embodiment 3:
Regulate the solution composition among the embodiment 1, proceed the bacteriostasis rate test of chemical composite plating.Wherein solution composition is to contain in every liter of plating bath: nickel sulfate content 18g/L; Ortho phosphorous acid sodium content 32g/L; Citric acid content 12g/L; Ammonium bifluoride content 29g/L; Thiocarbamide 1mg; Sodium lauryl sulphate 0.01g/L; Copper sulfate content 0.35g/L, nano-TiO 210gL -1Test-results shows:
The increase interval 0～0.4g/L of copper sulfate content in the plating bath, the first minimizing afterwards that be changed to of the wear weight loss of coating increases, the wear resistance increase of coating is because because the adding of copper, with infinitely solid solution of nickel, form sosoloid, reach the effect of solution strengthening, so along with the increase of copper content, the wear resistance of coating increases; The increase intensive of copper content has suppressed the deposition of phosphorus in addition, and when containing the phosphorus of lower aq in the coating, the wear resistance of coating is higher, so the wear resistance of chemical plating Ni-Gu-P coating is preferably.But when the copper content in the coating was too much, the wear resistance of coating reduced on the contrary, and this is increasing owing to copper, the downgrade of coating, surface irregularity, porosity increases, so bonding force also descends, coating is not wear-resisting, so copper sulfate content is 0.1～0.6g/L in the preferred plating bath of the present invention.When electroless plating begins along with TiO 2The increase of content, plating speed increases gradually, works as TiO 2Content is at 4g.L -1Time plating speed is the fastest to be 0.22706mg.mm -2.h -1, reach peak value, continue to add TiO afterwards 2, then gradually the decline of plating speed.
The antibacterial ability of titania powder itself is determining the Ni-Cu-P/ nano-TiO 2The antibacterial ability of composite deposite.Adopt the flask method of shaking that titania powder has been carried out the test of anti-microbial property, by titania powder is vibrated in bacteria suspension for a long time, the increase bacterium contacts with titanium dioxide, to show its anti-microbial effect.Test result is shown in Fig. 5 a, 5b.By Fig. 5 a, 5b as can be seen, add in the last substratum of titanium dioxide powder and the growth of bacterium do not occur, and do not add in the flask of titania powder, it is comparatively in great numbers that the bacterium in the bacteria suspension grows in substratum, can contrast the anti-microbial property of titanium dioxide excellence clearly.
In the plating bath of ternary Ni-Cu-P alloy layer, add 2～10gL -1Nano-TiO 2The back forms different Ti O 2The composite deposite of content, nano level TiO 2Adding make the anti-microbial property of coating that very large raising arranged, this can illustrate nano level TiO 2To killing intestinal bacteria is effectively, and this is because nano level TiO 2Particle diameter little, specific surface area is big, the surface atom number increases, the surface energy height causes nano-TiO 2The surface portion titanium atom lack the coordination of oxygen and be in oxygen debt state, TiO 2The outstanding key on surface forms defect level in energy gap, make TiO 2The surface have very high activity, thereby strengthened anti-microbial property.Each content TiO 2The antibiotic rate of coating all greater than 95%, TiO wherein 2Content is 4g.L -1The time coating antimicrobial ability be 99.7%.This be since composite deposite in except antiseptic elements such as copper, nickel element in action, the more important thing is nano-TiO 2Adding, owing to its anti-microbial property that receives the excellence that illumination produces makes the anti-microbial property of composite deposite reach comparatively ideal level.Though the test result according to anti-microbial property shows that the anti-microbial property of each coating is more or less the same, but certain trend is arranged, increase afterwards earlier and reduce, anti-microbial property has a peak value, and this can illustrate that in the test of anti-microbial property be not to add into TiO more 2Good more, as to show by each coating surface morphology nanoparticle TiO 2Compounding quantity as can be seen, coating composite Ti O 2Amount be limited, be dispersed in the TiO in the coating 2The effect of playing also is maximum, and its anti-microbial property also is best.
