Description
Technical field
The invention belongs to steel corrosion detection technique field, relate to a kind of method of testing with rust steel sample rusty scale and matrix bonding properties and device, be specially adapted to quantitative test band and become rusty the combination degree of steel sample Surface Rust and matrix.
Background technology
The corrosion of steel is a general and serious problem, and the loss that wherein atmospheric corrosion causes accounts for the half of whole corrosion loss.And the economic loss caused due to corrosion of steel structure every year accounts for 2% ~ 4% of national economy total output value.At present, the economic loss that causes because of corrosion of steel structure every year of the whole world is up to more than hundreds billion of dollar; Therefore, hold corrosion-prone problem in an atmosphere to solve steel, people have developed weathering steel.Weathering steel has good atmospheric corrosion resistance relative to carbon steel, and one of the main reasons is through long term atmospheric and is exposed to the sun, and define the protective rust being combined firmly, stablizing densification with matrix in its surface, it hinders entering of corrosive medium; And loosen at the rusty scale that steel surface is formed, not firmly, easily come off with matrix bonding properties and have micro-crack to exist, therefore can not play a protective role to matrix.
In order to evaluate weathering steel and carbon steel in dissimilar atmospheric environment form the protective effect of rusty scale to matrix; the particularly bonding properties of rusty scale and matrix; the correlation technique found at present has: " research of Protective Rust Layer Formed on Surface of Weathering Steel Panels and substrate combinating strength " that the people such as Zhang Quancheng deliver, and they are the interface bond strengths measuring weather-resistant steel plate rusty scale/matrix system with indentation method.The method needs to carry out thinning to steel sample Surface Rust, carries out indentation test afterwards with sclerometer under the load that applying is certain, gets its cracking or peels off diameter to investigate weathering steel rusty scale and matrix bonding properties.The method needs fixing sclerometer equipment, can destroy the matrix surface of steel sample after test, can not carry on next step corrosion rate test." impact that the synergy of Cu, Mn is corroded in simulated marine atmosphere environment low alloy steel " that the superfine people of Liu state delivers, they corrode element and chemical state thereof in the weightening finish rule of rusty scale, the growthform of rusty scale, thing phase, rusty scale with the means researchs such as weightening finish method, scanning electron microscope, X-ray diffraction, electron probe and x-ray photoelectron power spectrum 16Mn steel and Cu-Mn weathering steel under simulated marine atmosphere dry wet alternating environment.Weightening finish method is the growth rate embodying rusty scale in its rusty scale forming process, can not embody the bonding properties of rusty scale and matrix; Scanning electron microscope observes the pattern of rusty scale; X-ray diffraction is the phase structure of test rusty scale material; And electron probe and x-ray photoelectron power spectrum are chemical state analysis rusty scale being carried out to element depth analysis and alloying element respectively.They all directly can not react the bonding properties of rusty scale and matrix, and device therefor is very expensive." character of marine environment medium carbon steel Surface Rust and research method " that the people such as Zou Yan deliver, they mainly discuss pattern, the constitution and formation mechanism of steel surface rusty scale, utilize electrochemical impedance method to measure electric conductivity and the poriness of rusty scale respectively, utilize the corrosion speed of gravimetric method and electrochemical techniques measuring metallic materials.Little with the bonding properties relation of test rusty scale and matrix.
In sum, also do not have to destroy metal base surface at present, and can simple and easy to do, calibration tape rust steel sample rusty scale and the method for matrix bonding properties and device quantitatively, with the satisfied research different rusty scale of steel grade surface formation and the bonding properties of matrix in different environments, the therefrom corrosion stability of reaction material in its respective environment.
Summary of the invention
Not only for Problems existing during above-mentioned measurement metal base surface band rust steel sample rusty scale, the invention provides and a kind ofly do not destroy metal base surface but also can simple and easy to do, calibration tape rust steel sample rusty scale and matrix bonding properties and take into account the method and apparatus that simultaneously can test out the corrosion rate of its steel sample quantitatively.
The concrete technical scheme that the present invention takes is as follows:
The first step: the test steel sample of polishing of learning from else's experience carries out degreasing and neutralisation treatment, measures sample length, width and height after cleaning and dehydration, and to calculate its surface area be that S(is accurate to 0.01mm

2adhesive tape pair do not have the effect of stripping with matrix in conjunction with insecure rusty scale.
9th step: upper and lower surface is placed in up and down with the fixture of cushion by the band rust steel sample that adhesive tape is deposited with, guarantees that steel sample surface all can be stressed with cushion.
Tenth step: screwing fastening screw successively to steel sample surface pressing according to clockwise and middle part is 400 ± 5Pa, leaves standstill >=3min..Pressure <395Pa, adhesive tape is deposited with insufficient strength with matrix in conjunction with insecure rusty scale to steel sample surface; Pressure >405Pa, steel sample Surface Rust institutional framework can be destroyed.Standing <3min. also can cause adhesive tape not reach requirement with matrix in conjunction with the intensity that is deposited with of insecure rusty scale to steel sample surface.
11 step: fastening screw of outwarding winding successively, takes out band rust steel sample, takes adhesive tape off.
12 step: weigh and be only greater than 2.4N/cm with bond matrix intensity
2band rust steel sample quality be M
21(being accurate to 0.1mg).
13 step: repeat the 8th step ~ the 12 step, to M
2n-1-M
2n≤ 0.2mg, ensures allly all to be stripped in conjunction with insecure rusty scale with matrix.
14 step: band rust steel sample is put into 15% ~ 18% hydrochloric acid being added with 20g/L urotropine, and temperature is room temperature, removes all rusty scales on steel sample surface, with the naked steel sample of washed with de-ionized water, and with dehydration of alcohol, dries up with hair-dryer, put into exsiccator 2h.
15 step: weighing naked steel sample quality is M
