Indentation Creep and Adhesion of Hybrid Sol-Gel Coatings

Abstract:

In this study the creep behaviour and adhesion characteristics of hybrid sol-gel silica-based coatings on copper substrates was examined. Sol-gel technology was used to synthesize the organically modified silanes using mixtures of tetraethoxysilane and glycidoxypropyltrimethoxysilane precursors. The creep properties and adhesion behaviour of the coatings were assessed using nanoindentation and microtensile testing, respectively. The link between film structure and creep behaviour was explored. It is shown that the creep response of the coatings is influenced dramatically by the introduction and quantity of the organic substituent.
