The oxidation film layer that aluminium alloy minute surface glazed ceramic anode oxidation process described in embodiment 1-8 obtains has carried out a series of performance test, and method and the test result of test are as shown in table 1:

Table 1

As can be seen from Table 1, aluminium alloy minute surface glazed ceramic anode oxidation process of the present invention is compared with common anode oxidation process, the property indices of the oxidation mould obtained is better than common anode oxidation process, the most important thing is, the present invention can form various high glazed ceramic whites and other shades of colours in aluminum alloy surface, these colors can be black flower, under-glaze red, Ruyao yellow, black ceramic and whiteware glaze etc., and this is that common anode oxidation does not realize.

The property indices of oxide film that aluminium alloy minute surface glazed ceramic anode oxidation process described in exemplified 1-8 obtains has entered again to analyze and contrast by applicant, method and result as follows:

1, film performance test

1) rete dyeing behavior mainly observes the film surface colouring situation after dyeing process, as chromatophilia, homogeneity and washing etc.

2) erosion resistance of rete adopts the neutral salt spray test of standard (3 ~ 5%Nacl solution) and spot test to carry out the corrosion resistance nature of dyeing rete respectively.Spot test solution is 25ml hydrochloric acid, 3g potassium bichromate, 75ml distilled water, after sample oxidation is closed, carry out drop in 3h, and observe film surface drop and turn the green time, > 10min is qualified.

3) sun-proof of rete and the test of colour fastness sun-proof: be sample is placed on outdoor windowsill through tests such as Exposure to Sunlight wind and weathers, test point summer and winter two batches carry out, summer places 168h, observes after placing 480h winter, determines the surperficial changing conditions of dyeing oxidation film layer.

Colour fastness takes 2 kinds of modes to test: wax after the samples dried of Coloration occlusion with cotton, observes the pornographic condition of cloth surface band; Another method dyeing sample is placed in dehydrated alcohol soak, observe ethanol by colourless extremely time of variable color; Or dip in ethanol sample with absorbent cotton, observe the situation of degreasing cotton strip dyestuff.

4) cut resistance test uses PM-1 type frictional testing machines, with M20 abrasive paper for metallograph at load 90g, by sample reciprocating friction 1500 times, measures the weight loss of sample before and after friction.

2, the colour fastness of rete

As can be seen from Table 2, aluminium alloy enamelled anodizing film is dyed, after fixing color and sealing, colour fastness is extraordinary, and more suitable than the dyefastness of sulphuric acid oxidation coating.Then fairly fade without fixation, closed dyeing film, so the color stability of fixing color and sealing operation antianode oxide film is very important.In addition, slightly fade although some color and luster retes have in wiping, increase cloth further and wipe number of times, then the degree of fading can not increase a lot, shows that the color easily fallen just is attached to surface, and the pigment in rete hole is then firm.Also have the colour fastness of red colouration, yellow, chrome yellow, flesh pink, black relatively good, but dye blueness, purple, green its colour fastness of rete are not so good, this may be relevant with the kind of dyestuff.

Table 2 ceramic oxidizing rete color fastness testing result

The rete sample that will dye soaks through anhydrous ethanol solvent and finds, enamelled anodizing film Coloring Time is in ethanol on the whole than the time long (20 ~ 30s) of sulphuric acid oxidation coating, especially with red and yellow Coloring Time the longest (> 30min), purple and green Coloring Time the shortest (30 ~ 40s); Show by ethanol result simultaneously, sulphuric acid oxidation coating (purple) seriously fades, and enamelled anodizing film is except purple, all do not fade, can illustrate that fixing color and sealing one step process of this research is very favorable for the dye stability of anode oxidation membrane.May be the associativity that encapsulant composition strengthens dye molecule and oxidation film layer hole dyeing while, colour fastness is improved.Purple and green dye molecule may be then more weak with the chemical bonds of anode oxide film hole wall, and fastness is deteriorated.Therefore, although dyeing solidification is closed can improve the dyefastness of rete, select suitable, to be easy to firmly be adsorbed on the intrapore dyestuff of oxidation film layer be also very important.

3, the solidity to corrosion of dyeing rete

Several different ceramic oxidizing retes of table 3 and common sulphuric acid anodizing dyeing rete are through the result of neutral salt spray test, can find out that all sample film surfaces all do not corrode, major part specimen surface color and luster is unchanged, have certain anti-brine corrosion ability, the specimen surface color and luster of only have illicit sexual relations purple and red colouration slightly shoals.

The result of the dropping corrosion test carried out in addition also can find that colour porcelain film and oyster white porcelain film all have excellent erosion resistance, no matter be electrochemical enamelizing or sulfur acid anodizing rete, or the surface color of oxidation film layer is different, its drop Coloring Time is all greater than, and illustrates that the rete of enamelled anodizing poststaining sealing one step process is the inspection that can meet this anti-corrosion test method.

Table 3 anodization for porcelain like film neutral salt spray test result (48h)

4, the sun-proof of rete and weathering resistance

Table 4 is anodic oxidation dyeing sample surface color changing conditions after outdoor placement certain hour, its objective is the weather-proof and light permanency investigating ceramic oxidizing dyeing rete.Summer placed, through exposing to the sun and rain, found that, colour porcelain oxide film is due to the difference that dyes, but exposing to the sun and rain through aestivate, film surface color and luster all changes, wherein the rete color and luster change of red colouration, flesh pink, black is less, show that its weathering resistance is better, and the weathering resistance of the ceramic oxidizing rete of green colouring is the poorest, this is relevant with the kind of dyestuff.Exposing to the sun and rain in addition through winter, the weathering resistance of rete is better than summer, and mainly the Exposure to Sunlight temperature in winter is low, and the reason do not drenched with rain winter.Colour porcelain film and sulfur acid anodizing film (dyeing) sun-proof, weathering resistance are similar on the whole, show that this colour porcelain rete has good weathering resistance and light permanency.

5, cut resistance test

Table 5 is dyeing rete weight losses after 1600 frictions, can find out, does not have the weight loss of ceramic oxidizing rete and the sulfur acid anodizing rete dyeed all smaller; And it is larger than the weight loss of achromophil anodization for porcelain like film through hyperchromatic porcelain film, after dyeing is described, dyestuff enters except oxide film hole except adsorbing, some dyes may be also had at film surface, along with the carrying out of surface friction, its weight loss than undyed ceramic oxidizing rete weight loss more greatly.
