对于碳化物的提取,通常采用非水溶液低温电解提取的方法,而且多用甲醇(也有乙醇)基液(以下简称在低温下电解、以甲醇为基液的方法为A;乙醇为基液的方法为B)。因为是在低温下电解提取,操作不方便,而且甲醇影响操作人员健康。本试验是探索一种提取Ni-Cr-Mo-Ti-Nb和Ni-Cr-W-Mo-Al-Ti合金中碳化物的方法,使操作简便,而且对操作人员无毒,同时能获得光滑的电解区表面,有较高的收得率,有可靠的分析结果。一本方法的基本思想常用的方法A或B的电解液组分中含有5%盐酸,1%酒石酸,10%丙三醇。在—5℃以下,以0.1A·cm~(-2)的电流密度电解60分钟。本试验是以乙醇为基液,希望在室温下提取碳化
For the carbide extraction, usually non-aqueous solution of low-temperature electrolytic extraction method, and more with methanol (also ethanol) base liquid (hereinafter referred to as electrolysis at low temperature, methanol as a base solution method is A; B). Because it is extracted at low temperature electrolysis, the operation is not convenient, and methanol affect the health of operators. This test explores a method for the extraction of carbides in Ni-Cr-Mo-Ti-Nb and Ni-Cr-W-Mo-Al-Ti alloys that is easy to operate and non-toxic to the operator while achieving a smooth The electrolysis area surface, a higher yield, a reliable analysis of the results. The basic idea of a method commonly used method A or B electrolyte components containing 5% hydrochloric acid, 1% tartaric acid, 10% glycerol. Below -5 ℃, the current density of 0.1A · cm ~ (-2) electrolysis for 60 minutes. This test is based on ethanol, hope to extract carbonization at room temperature
