| Outline of Final Research Achievements |
To improve efficiency of coating process of ship's hull, relation between the size, velocity and properties of the spray droplets and surface roughness of the coating film was quantitatively investigated. For the quantitative investigation, model experiments of coating process were conducted. Roughness of paint film which formed using actual paint was measured. Summarizes these results, a prototype of coating quality simulation program for obtaining the surface roughness of the coating from the droplet conditions.
