Investigating the abrasive wear behavior of locally used automotive paint

Abstract EN

The objective of this research is to investigate the abrasive wear behaviour of polymer base automotive paint, which is locally used for steel painting.

Research has been conducted under dry, water lubricated, and water-soap lubricated conditions.

The effects of applied load, sliding distance, abrader surface roughness, and paint drying time on the abrasive wear volume and abrasive wear rate were investigated under controlled environment of 23°C temperature and 40 % humidity.

The examined paint was used directly on steel substrate with no primer.

Preliminary results show that wear volume increases with increasing applied load, sliding distance and abrader roughness.

However, results also show decreasing wear volume with increasing drying time up to 50 hr.

Beyond this value, time seems to have little effects on abrasive wear behaviour.

This argument is valid for all four conditions of tests.

As for abrasive wear rate, results show decreasing abrasive wear rate with applied load sliding distance, abrader surface roughness, and drying time.

Results clearly indicate that the presence of water significantly increases the wear volume and wear rate.

Furthermore, the addition of soap to water increases the wear volume and rate to even higher levels.
