Special coatings
A professional tool manufacturer for carpenters wants to find an alternative solution to the hard chromium coating in the projection cylinders.
The tools are made of aluminum cylinders in which a segmented piston slides. The aluminum cylinders emerging from the foundry are nickel-plated and then chromium-plated, before undergoing a final boring. The project is to develop a dry-lubricating (sol-gel) coating that replaces metallic coatings.
To develop a sprayable composite sol-gel coating bonded to aluminum or magnesium foundry. This coating must withstand a temperature of about 150-200 °C and must lubricate the piston rings in the cylinder for 200 000 uses.
A composite sol-gel based on organosilanes and a lamellar material has been developed. Spray deposition allows to obtain micronic layers perfectly adherent on aluminum or on magnesium with a controlled thickness. The technology meets the requirements with a simplest process and at lower costs. It allows a weight gain of the tools when aluminum is substitute by magnesium.
An industrialist wants to evaluate alternatives to alodine 1200 for light aluminum alloys.
To develop a thin uniform colored coating with similar performance to alodine 1200 in terms of adhesion, corrosion resistance and conduction. The solution must be Chromium free.
Develop a conductive, highly-adhesive sol-gel coating on 2024 alloys, applicable by spray or brush, and effectively protect against corrosion (180 to 500 h of BS)
We developed a hybrid composite coating with anti-corrosion properties (BS 500h), with transverse electrical resistance meeting the MIL-DTL-81706 standard. The work focused on mastering the synthesis of the conductive elements and the hybrid matrix, from the laboratory scale to the pre-industrialization.
