Magnesium Plating and Assembly for Advanced Applications

Objective



Today, the consumption of magnesium alloys for structural
applications in the automotive, aeronautics and space
industries is stagnating, or even decreasing, compared to
the 1960s. And yet magnesium is the highest of all
metals and one the most abundant and most easily
machinable and castable ones. It also has very good
mechanical characteristics.
Although a new generation of Magnesium alloys has been
emerging, some denser metals such as titanium and
aluminium, or some more costly materials like the
composite materials, are now being preferred.

Why are magnesium alloys neglected?
for two basic reasons:
low anti corrosion performance,
lack of confidence from the industry, due to past,
sometimes disastrous, experiences.
Now, here is our CHALLENGE: to develop some insulating
or conductive surface treatment techniques based on
chemical or physical deposits for enhanced corrosion
resistance, as required by the very nature of magnesium,
i.e.: magnesium is the most electronegative practical
metal in the periodical table of elements, magnesium
exhibits an anodic character in relation to the
assemblies. The aim is to increase corrosion resistance
by 30%, compared to the treatments currently available on
the Magnesium market, while preserving the environment
(not using chromium VI, for example).
to validate the technologies we shall develop
to set the design and operating rules needed for using
magnesium.
If these two gaps were filled, this would immediately
open the way for a great number of applications. The
fields of application involved in the proposal are the
following:
automotive, space, aeronautical, railway industries
communication industries: portable systems
(computers, telephone sets, etc.),
and any other industries where weight necessarily has
to be reduced to lower the consumption of fossile
energy and for preserving the environment.

To reach the MAGPLAT objectives, the Project which lasts
3 years, gathers 8 partners from 4 European Union
countries. Users from Automotive, Aeronautics and Space
industries will define with the developers the alloys to
be used and the anti corrosion level to be reached to
lead to a reliable and cost effective material
protection process. The Consortium, coordinated by a
dynamic SME specialised in material surface coating and
protection, associates in well balanced manner SMEs (3)
and big companies (3) with research center either
institute (1) and University (1). The expected gain in
term of anti corrosion behaviour will be at least 30%
over the currently available techniques, together with
excellent performances in term of life cycle and aging
time.
