Technique de la productionIndex. décimale : 667.9 Revêtements et enduits Résumé : In the Bonfiglioli gearbox plant, the coating process has to meet high standards. By setting a very strict compliance threshold and monitoring the coating parameters carefully it has been possible to achieve the required coating quality. One decisive factor is the use of carefully coordinated proportioning, mixing and spraying equipment. Note de contenu : - Monitoring the coating process at every stage
- Spray booths with robots
- New proportioning system improves quality
- Benefits of automated application
- Reducing the frequency of cleaning and filling cycles
- High-quality protective coatings for gearboxes
- Fig. 1 : A modern proportioning, mixing and spraying system is used for the gearbox coating processes in the Bonfiglioli plant. The benefits include increased efficiency and productivity
- Fig. 2 : Coating gearboxes is a complex process. The protective coating must be applied evently to all the areas particularly at risk of wear and corrosion
- Fig. 3 : The proportioning systems are designed for manual processing, but a PLC allows the two devices to function as semi-automatic systems and to interact to a limited extend with the coating robots
- Coated parts in the gearbox plant in Forli. The two main benefits of automating the process are the reduction in paint use and the shorter colour changesPermalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=30992

Revêtements protecteursIndex. décimale : 667.9 Revêtements et enduits Résumé : E-coat, liquid and powder : there are many different coating options available for the ACE and home appliance markets. Both the one- and two-layer systems offer combinations that can meet the sectors' needs and specification for performance, corrosion protection and gloss and colour retention. However, as these markets becomes more demanding, coatings manufacturers like Axalta must work ever more closely with their customers to create specific solutions that address both practical and financial demands by continually developing high-quality, cost-effective technologies.

vernis en phase solvantIndex. décimale : 667.9 Revêtements et enduits Résumé : The relations between evaporation of clearcoat solvents and various operating parameters of the spray from a rotary bell atomizer were measured using a particle dynamic anemometer (PDA). The robot arm holding the spray applicator was moved relative to the PDA so that the volume flux at different parts of the spray could be measured. The difference in total flux between two planes, perpendicular to the spray axis, was considered to be equal to the evaporation. Evaporation was found to increase with increasing bell speed. Evaporation also increased with increasing coatings flow rate from 100 to 200 cm3/s flow rate, but not for a further increase to 300 cm3/s. Higher electrostatic potential, bell speed, and lower flow rate decrease the mean particle diameter. Particle mean velocity increases with increasing bell speed and flow rate. Coatings flow rate, bell speed, electrostatic potential, and the interaction between flow rate and bell speed were significant factors affecting evaporation rate. Of the former three, coatings flow rate was the most influential.

Surfaces fonctionnellesIndex. décimale : 667.9 Revêtements et enduits Résumé : Ceramic fibers were functionalized by the sputter coating of copper in this study. The surface and interface structures of the functionalized ceramic fibers were investigated by atomic force microscopy (AFM) and environmental scanning electron microscopy (ESEM). The observations by AFM revealed the formation of nanoclusters on the fiber surface. The coated layer of the sputtered copper was also confirmed by the ESEM examination, equipped with an energy-dispersive X-ray analysis. It was also found that the electrical resistance of the ceramic fibers decreased with increased coating thickness. The interfacial bonding between fibrous substrate and sputter-coated copper was investigated and discussed by peel-off tests in this study. The mechanism of the interfacial adhesion between copper and fiber substrate was also discussed.
