Abstract
A multilayer paint modelling study was conducted to investigate the erosion properties of different types of paints. The experiments were carried out in a slurry-mixing tank in which 10 painted samples mounted on a shaft were rotated at constant speed for a certain interval of time. The effect of impact angle on the particular type of paint was investigated by orientating the samples consecutively at angles from 0° to 90° with an increment of 10°. In the slurry medium, it was found that most soft paints, such as “Enamel” type have similar erosion maps to ductile materials with a maximum wear rate at around 30°. Metallic paints and styrene type paints have shown a slightly higher angle of 40° for maximum erosion. In laboratory modelling, erosion studies of ductile materials by multilayer paint techniques are time and cost-effective.
