钛合金阳极氧化膜层影响因素的研究与应用
|
摘要
钛合金具有重量轻,密度低,强度高,耐腐蚀性好等优点,在国民经济和国防工业上的应用越来越广泛,但也存在耐磨性差,与其他金属的接触腐蚀等缺点。为了改善其性能,需要对钛合金进行表面处理。钛合金有许多表面处理技术,其中钛合金的阳极氧化处理技术因工艺简单,在实际生产中得到广泛应用。钛合金阳极氧化处理时氧化膜层的厚度和颜色,与电解液的组成和温度、电流密度、电压、时间等因素关联,研究这些因素对钛合金阳极氧化的影响,从而解决工程实际问题。
Generally,titanium alloys have the advantages of light weight,low density,high specific strength,and good corrosion resistance.It is clear that titanium alloys are widely used in the national economy and defense industry.However,it seems that titanium alloys have some disadvantages such as poor wear resistance and contact corrosion with other metals.In order to improve its performance,it is sure that titanium alloys need to be surface-treated.On the other hand,titanium alloys have many surface treatment technologies,among which the anodizing treatment technology of titanium alloy is used in actual production due to its simple process.Similarly,it is certain that the thickness and the color of the oxide film during the anodizing of the titanium alloy might be related to the composition and temperature of the electrolyte,current density,voltage and time.Therefore,the effect of these factors on the anodic oxidation of titanium alloys would be investigated so as to solve engineering problems.
