CS237966B1 - A method of pretreating a product surface prior to amalgamating - Google Patents

Abstract

The solution relates to amalgamation of metals. The aim of the solution is to improve the quality of amalgam on ferrite products and increase its service life. The method of pre-processing the product before amalgamation includes etching, pickling, galvanic deposition of a mercury-soluble metal, for example silver. According to the solution, in the period between pickling and galvanic deposition of a mercury-soluble metal, the product is gradually subjected to heating, chemical and electrochemical copper plating and nickel plating.

Description

(54) Method of pre-treatment of the surface of products before amalgamation

The solution concerns the alloying of metals.

The aim of the solution is to improve the quality of amalgam on ferrite products and increase its service life.

The method of pre-processing the product before amalgamation includes etching, pickling, galvanic deposition of a metal soluble in mercury, for example silver.

According to the solution, in the time between pickling and galvanic deposition of mercury-soluble metal, the product is gradually subjected to heating, chemical and electrochemical copper plating, and nickel plating.
