Abstract

The results of structural and corrosive studies of copper-tungsten composite material obtained by electron-beam evaporation and subsequent condensation in vacuum. It is shown that the copper-tungsten condensate is a gradient material, lamination which increases with increasing content in the tungsten. Gravimetric studies, analysis of the corrosive protection and corrosive chart showed that with increasing content of tungsten in the condensates corrosive resistance increases. Structural studies have confirmed an increase in corrosive resistance with increasing tungsten content in the condensates. At the microscopic pictures taken after the corrosive tests, for condensates with the content of tungsten is greater than 15% destruction of the material is not fixed
