Abstract

The wear behaviour of bare and polymer-coated soda-lime glass specimens sliding against 440C stainless steel counterfaces was investigated with the aid of a pin-on-disk apparatus. The selected polymeric coatings were commercially supplied safety films, which are nowadays extensively applied on glass in the automotive and construction industry. One of their main failures is the degradation of their properties due to wear. In this work, the frictional behaviour of these coatings on glass were evaluated and compared to those of bare soda-lime glass. Correlations have been also made between the worn surfaces and weight loss in order to investigate the effect of wear conditions (speed, load) on the wear behaviour of these tribosystems. In addition, during the dry wear of soda-lime glass sliding against stainless steel counterfaces, the dominant wear mechanisms were found to be localized adhesion and abrasion, whereas, in the case of the multilayered polymeric coatings localized adhesion, deformation and tearing were observed.

Highlights

Ceramic materials, because of their excellent technological properties, such as strength, hardness, chemical inertness, and thermal shock resistance, have been used in many technological fields and manufacturing applications
The various glasses are promising for use in industrial and technological areas [1,2,3,4]
Several aspects need to be addressed before they can be applied to even more fields of application. One of these aspects is their tribological properties, as most glasses are found to have relatively low resistance to wear [5,6] due to their considerably low fracture toughness [7,8]. It has been found [9,10,11,12] that the abrasive resistance of glasses strongly depend on the wear conditions, which determine the occurring wear mechanisms

Summary

Introduction

Because of their excellent technological properties, such as strength, hardness, chemical inertness, and thermal shock resistance, have been used in many technological fields and manufacturing applications. Several aspects need to be addressed before they can be applied to even more fields of application One of these aspects is their tribological properties, as most glasses are found to have relatively low resistance to wear [5,6] due to their considerably low fracture toughness [7,8]. During the abrasive wear of soda-lime and borosilicate glass, abrasive debris particles form and agglomerate at the contacting interface [9,10]. Chemical analysis of these particles showed that they consisted of both tribomaterials (glass and metallic countermaterial)
