A METHOD OF MAKING MESH FILTERS FROM MATERIALS AND ALLOYS.
Abstract
The object of the invention is a method of making mesh filters from metals and alloys by selective anode etching, in solutions of hydrochloric acid or its salts, of initial billet from a foil obtained by rolling or by pressing and sintering metallic powders. To intensify the process and improve the quality of the mesh, electrolysis is conducted under conditions set forth in the disclosure. To obtain a mesh from metals and alloys that cannot be etched (for example, tungsten, molybdenum and tantalum) other metals (for example, zinc, cadmium, iron) that form structural components in the composition of the alloy that are soluble in the selected electrolite are introduced into the composition of the initial billet.
