Method of preparation of the surface of the pieces of uranium or uranium alloy a base

摘要

The invention relates to a method of preparation of the surface of the pieces of uranium or an alloy based on uranium. / p & & p & this process comprises a step of chemical etching of the surface of the piece of uranium or uranium alloy by means of a solution of nickel chloride and hydrochloric acid, for example containing 600 has 700g.l of nicl.sub.2 and 1,8 is 2,2 mol.l of hcl. / p & & p & of the nickel coatings carried out by chemical nickel plating can then be deposited on the pieces thus treated.
