Study of optimal parameters of degreasing and etching of superconducting materials

The superconductors are materials in which there is a unique phenomenon of superconductivity linked so that an electric current, once induced in a superconducting circuit, will be a long time to circulate through this circuit without appreciable reduction of their power without additional energy supply. The practical use of superconductors opens wide prospects for solving a number of problems where the use of conventional electrical materials uneconomical or impossible in principle. Manufacture of superconducting materials, passing several stages is quite complex and costly process. To reduce the cost of studies have been conducted to reduce the concentration of nitric acid in half on a hexagonal bronze and niobium rods, which are used as components for superconducting materials. Causing the time degreasing is reduced more than in 2 times that allows to increase the performance of superconducting materials without degradation of the treated surface.
