Effect of temperature on wear behavior of multilayered thin cr-coated acrylonitrile-butadiene-styrene polymer: An experimental and prediction study

Abstract

The wear behavior of thin chromium-coated and uncoated acrylonitrile-butadiene-styrene (ABS) samples were investigated by using a pin-on-disk test apparatus with a heat chamber for different temperatures of 30°C, 50°C, 70°C, 90°C, and 110°C. The wear tracks were characterized with a scanning electron microscope, energy dispersive X-ray spectroscopy, and widefield confocal microscope. The tests showed that the wear of thin chromium-coated ABS samples exhibited better results under high temperature in comparison with uncoated samples. Then, the experimental data are used to create Nonlinear AutoRegressive with eXogenous inputs (NARX) and transfer function prediction models for wear experiments. It is observed that the NARX model matches quite well with the experimental data. Copyright © 2021 by ASTM International.
