Graphen zink alloy coating on steel wire

Reference number
Coordinator Swedwire AB
Funding from Vinnova SEK 74 958
Project duration November 2017 - April 2018
Status Completed
Venture Strategic innovation program SIO Grafen

Purpose and goal

The project aims to provide available information on how the graph can be used to strengthen the corrosion protection properties of zinc as a surface coating on steel wire. And how to apply this in a galvanizing process of the drag wire. The information collected has strengthened the knowledge in the field and possible processes for mixing zinc and the graphene have been identified.

Expected results and effects

No studies or published patents have been found within the subject of graphene/zinc coating. A process for mixing graphene in other metals could be identified and formed the basis of the prototype tests carried out. Big difficulties arose trying to get a homogeneous blend of zinc and graphene as there is no natural driving force for zinc and graphene to blend.

Planned approach and implementation

The project was carried out in 2 parts. Part 1 Preliminary study: with the aim of taking advantage of studies already completed in the field Part 2 Prototype test: With the help of the information obtained in the preliminary study, conduct a small-scale test where a steel wire is coated with a zinc / graphene layer and then tested for its corrosion resistance. Difficulties in identifying a working method for mixing zinc and graphene resulted in that no prototype test could be carried out. Hence Part 2 of the project was solely focused to identify a working method for mixing graphen with zinc.

The project description has been provided by the project members themselves and the text has not been looked at by our editors.
