采取积极的保护措施,因此造成的自然环境腐蚀造成的经济损失降到最低。本文的目的是与国家重点基础研究发展计划(973)的腐蚀和金属材料研究工作的自然环境项目,针对不同的测试要求简单的现场开发出腐蚀检测设备。研究工作文件由两个部分组成:
Take positive protective measures, so the economic loss caused by natural environment corrosion is minimized. The purpose of this paper is to develop a simple corrosion detection equipment for different testing requirements in accordance with the national key basic research and development program (973). The working paper consists of two parts
一个检测器是基于大气腐蚀电开发,检测器的性能测试包括误差分析,电偶腐蚀测试和电偶腐蚀测试中的溶液环境在该薄膜,以及用于在大气腐蚀LY12铝合金薄不同氯化物研究膜中的浓度,表明该检测器具有更好的性能。
A detector is developed based on atmospheric corrosion electricity. The performance test of the detector includes error analysis, galvanic corrosion test, solution environment in galvanic corrosion test, and the concentration of different chlorides in the thin film used for atmospheric corrosion of LY12 aluminum alloy. The results show that the detector has better performance.

第二,金属材料的腐蚀开发了基于检测器稳压器/恒流电路和性能测试。检测器显示出良好的仪器漂移特性,负荷特性,快速的响应时间,大范围允许电容性负载。内置较少的可用和波形发生器波形振幅,低频值的类型,如果虚拟仪器提供波形检测器的功能扩展检测器。通过与测量探测器RP也表现出更好的性能。

Second, corrosion of metal materials was developed based on detector voltage regulator / constant current circuit and performance testing. The detector shows good drift characteristics, load characteristics, fast response time and wide range of capacitive load. Built in less available and waveform generator, waveform amplitude, low frequency value type, if virtual instrument provides waveform detector function expansion detector. By comparing with the measured results, the detector RP also shows better performance.
这两个检测器具有较少的控制,操作简便;使用作为电解池口的空气塞,安全可靠;220V交流电源使用,方便,可靠;数字面板表显示等.。后,将溶液治疗双金属复合衬板改进的性能主要是由于溶液处理合金的Cr后的合金,Mo增加固溶的程度,并在固溶处理还消除金属间化合物的合金的有害性质。
The two detectors have less control and are easy to operate; It is safe and reliable to use the air plug as the opening of electrolytic cell; The use of 220 V AC power supply is convenient and reliable; Digital panel, table display, etc. After the solution treatment, the improved properties of the bimetal composite liner are mainly due to the increase of the degree of solid solution and the elimination of the harmful properties of the intermetallic compound alloy.
与普通压→1360?0C/2H真空烧结工艺路线相比,镍-铬-钼合金耐海水强度可通过1225?0C/40分钟压制→1300?0C/4H溶液处理工艺路线,可塑性和耐腐蚀性较高,其σ_b715MPa,6月17日.2%时,腐蚀速率为0.051毫米/A。所以1225?0C/40分钟压制→1300?0C/4H溶液处理工艺路线为最佳行车路线。这也研究了合金元素W,铜与Ni铬钼及其机理海水耐腐蚀合金的机械性能,耐腐蚀性能。
Compared with common pressure → 1360? Compared with 0C / 2H vacuum sintering process, the seawater resistance of Ni Cr Mo alloy can be improved by 1225? 0C / 40 min pressing → 1300? 0C / 4H solution treatment process has high plasticity and corrosion resistance σ_ The corrosion rate of b715mpa was 0.051 mm / A on June 17 at 0.2%. So 1225? 0C / 40 min pressing → 1300? 0C / 4H solution treatment process is the best route. The mechanical properties and corrosion resistance of W, Cu, Ni, Cr, Mo and their mechanism seawater corrosion resistant alloys were also studied.
研究表明:双金属复合衬板,而加入合金元素钨,铜,其σ_b到694MPa的综合性能最好Cu2W,Δ15.8%时,腐蚀速率为0.002毫米/A。这是由于强烈的合金元素W的固溶强化成分,同时信铬钢堆焊耐磨板(8+8、6+6、12+8)允许具有抗氯?镍基合金-在缝隙腐蚀,点蚀和Cu是合金元素的更正电位,其中,所述腐蚀过程可以富集合金表面,更稳定的钝化膜,并进一步提高该合金的耐腐蚀性。
The results show that the bimetallic composite liner, with the addition of alloying elements such as w and Cu, has better mechanical properties σ_ The comprehensive performance of cu2w from B to 694mpa is the best, Δ 8%, the corrosion rate is 0. 002 mm / A. This is due to the strong solid solution strengthening composition of alloying element W. at the same time, it is believed that chromium steel hardfacing wear-resistant plates (8 + 8, 6 + 6, 12 + 8) are allowed to have chlorine resistance? Nickel base alloy - in crevice corrosion, pitting and Cu are the corrected potentials of alloy elements, in which the corrosion process can enrich the alloy surface, more stable passive film, and further improve the corrosion resistance of the alloy.
