Summary on Grant Application Form |

The SERC supported Newcastle Nanoindenter facility has been fully commissioned and has allowed a considerable new understanding to be gained of the ways in which continuously recording load:displacement methods can be used to quantitatively characterise the elastic, plastic and fracture response of ceramics and hard coated-materials to surface contact. Often, this is the only way of investigating the properties of materials at current (sub-micron) microstructural scales. The proposed new programme is to extend several areas of study and pursue a number of new avenues with our established technical skills and knowledge base. First, considerable further work is required to fully understand the contact response of coated systems, especially as a function of substrate deformation character and the residual stress state of the coating. Recent work also suggests that many diamond-like films exhibit nano-scale creep and thus can readily be investigated. Further, we can now successfully address the application of nanoindentation methods to detect the presence of soft absorbate-controlled films (eg hydrated layers) on engineering ceramics, the point to point differences in response of mixed phase polymers and the crushing strength and mechanical properties of spheres and powders (relevant to their mechanical response during compaction etc). Completely new investigations will cover the development of higher load techniques to fibre-pushing, the application of a new nano-scratch facility and the contact fatigue of ceramics and coatings.
