Description

Purpose and areas of usage
The development belongs to the field of surface processing of metal products, in particular the pre - treatment of steel products before applying metal, polymeric or composite coatings of various purposes. It is designed to increase the solidity of their adhesive connection.


Main characteristics. gist of development
The development allows to obtain the roughness of steel products with irregular microrelief due to the formation of a underlayer of the auxiliary coating with a Fe - Zn alloy. It is deposited electrochemically from the proposed economic sulfate electrolyte at a cathode current density of 8 - 12 A / dm2 and a temperature of 50 - 60 °C using iron muds or steel anodes. After application of the adjuvant coating, the surface roughness of the products of low carbon steel is: Ra = 4. 5 microns, Rmax = 36 microns. Adhesion tests of polymeric coatings based on aromatic polyamides applied to the developed Fe - Zn support coating showed increased adhesion strength to the level of cohesive polymer destruction.

Main advantages of development
The development makes it possible to obtain the roughness of steel products in a more cost effective way with lower capital and energy expenses compared to the world's counterparts.

 

Market demand
The development can be effectively used in the pre - processing of steel products at the enterprises of mechanical engineering, metal working and automotive industry.
