Assembly - January 2009 - (Page 20) Assembly Innovations and inhibitors can be adjusted to suit a variety of surfaces and applications. “Although we concentrated on corrosion, our method could also be applied to self-repairing coatings for antifungal or antifriction applications,” says Andreeva. One practical problem the MaxPlanck team is still working on is how to automate the layer formation procedure for mass-production applications. Beyond that, they are already developing other anticorrosion formulations. A German research team has invented a self-healing, nanoscale coating that may someday replace the anticorrosion materials currently being applied by the automotive industry.

Controlled release of the inhibitors is stimulated by the presence of corrosive agents, while the polyelectrolyte layers buffer pH changes at potentially corrosive areas. In addition, because the polyelectrolyte constituents can move from layer to layer, the coating can heal itself when damaged. The chemistry of the process is versatile. The mix of polyelectrolytes hether a bolt is tightened by an air tool, a pulse tool or a computer-controlled electric tool, engineers can never be absolutely certain how securely the joint has been fastened. That’s because engineers measure torque to assess the tightness of the joint, when what they really want to measure is clamp load. 2D and 3D File Downloads available at www.weissna.com Technology that inspires The TC Standard Cam Indexer.
