Anti-corrosion solutions

Objective

 

ArcelorMittal wants to propose new solutions to cut the cost of corrosion protection for car makers.

 

Main activities

  • Development of new highly corrosion-resistant coatings as cost competitive alternatives to replace the secondary measures for corrosion protection (e.g application of waxes and sealers aiming at preventing perforating corrosion and corrosion on cut edges)
  • Technical support to clients in the field of corrosion (e.g. understanding and solving of corrosion problems, testing of coatings to be self agreed)

 

General approach

  • Complete elaboration and characterisation of new metallic coatings
  • Intensive collaborations with resin suppliers to evaluate new organic coatings: low cost solutions with high level of performances (both on EG substrate and on GI substrate)
  • Development of methodologies to evaluate corrosion as it occurs on vehicles (perforating corrosion, corrosion on edges etc.). A special effort is made to propose and validate methods to enable to quantify corrosion damage precisely (by laser triangulation for instance)

 

Main anti-corrosion competences

 

Corrosion during storage of the coil
  • Temporary corrosion resistance
  • Efficiency of inhibitive solutions/oils
  • Corrosion resistance of coated/uncoated steel


Corrosion on vehicles


  • Perforation corrosion resistance
  • Cosmetic corrosion resistance
  • Influence of painting conditions on corrosion resistance
  • Influence of forming on corrosion resistance
