Although the scratch test has now become commonplace both in the research field as a
measurement tool and in industry as a Quality Control (QC) tool, the utility of this technique …

Mar is a type of subtle surface damage caused by a sliding object barely visible to human
eyes. This minor damage phenomenon has rarely been systematically studied. Significant …

Rockwell C diamond indenter with a spherical tip of radius of 108 μm was used to slide on
bulk polycarbonate under linearly increasing normal load from 5 mN to 20 N in order to …

For the scratch process of polypropylene (PP), the stick-slip phenomenon always exists and
contributes to the observed periodic surface damage patterns. The stick-slip, one main …

To investigate the scratch behavior of short glass fiber (SGF) reinforced polybutylene
terephthalate (PBT) composites, the scratch tests with the progressively increasing normal …

In this work, an in-situ observation of temperature rise during the scratch test was performed
for both brittle and ductile polymeric materials, ie, poly (methylmethacrylate)(PMMA) and …

The mechanical properties, the scratch resistance and the surface damage mechanisms of
organic lenses and transparent anti-scratch and antireflective coatings, commonly used in …

Fullerene (C60) is used to prepare a high-performance epoxy nanocomposite having
enhanced antiscratch performance. Herein, C60 was oxidized and then silanized using 3 …

In this study we present a new in situ real-time approach to perform and analyze scratch
tests of transparent coating/substrates systems. This method allows for the observation of the …

The present study investigated the geometrically necessary dislocation (GND) with the
influence of the surface roughness by establishing the relation of roughness in GND for …
