Important results from the project
The aim of the project is to develop and optimize a sustainable process for anodization of aluminium followed by impregnation of the anodic coatings using nanomaterials to produce innovative, multifunctional surfaces. The initial approach is to develop corrosion inhibitory nanomaterials to enable corrosion protection with added values and additional material related functionalities where special focus will be on low ice-adhesion.
Expected long term effects
Optimize a sustainable anodization technique and combine it with nanoparticle deposition for the development of corrosion resistant and highly ice-repellent surfaces. The successful results obtained from the project enables production of sustainable multifunctional surfaces. The newly developed procedure enables reduced environmental impact by using more environmentally friendly materials and reduced number of production steps. Lowered adhesion of ice on aircraft parts also reduce the environmental impact by reduced fuel consumption and by that lower CO2 production.
Approach and implementation
The project was led by Linköping University in collaboration with Saab and RISE. A method for cerium oxide based nano-impregnation was developed and characterized by Linköping University who also did corrosion trials. Saab gave input regarding traditional industrial processes and requirements. Saab provided samples surface treated using conventional methods as reference. RISE performed ice adhesion measurements and provided information and knowledge regarding requirements for low ice adhesion
