Title: | Fabrication, characterisation and property modelling of TiB2 based nanostructured coatings | Authors: | Nurot Panich | Keywords: | DRNTU::Engineering::Materials::Nanostructured materials | Issue Date: | 2007 | Source: | Nurot Panich.

Doctoral thesis, Nanyang Technological University, Singapore. | Abstract: | Fabrication and development of TiB2-based nanostructured coatings and the development of finite element (FE) models to simulate the nanoindentation and micro-scratch test processes in various coating systems were investigated in the present work. By varying the sputter-target power density, substrate temperature, deposition time, substrate-totarget distance, substrate rotation, substrate biasing and substrate sputter cleaning, the relationship between the sputtered structure properties and sputtering conditions were established. In order to increase the coating/substrate adhesion, interlayer and multilayer techniques between TiB2 and tough material, e.g. Ti and Cr were proposed and employed. Furthermore, techniques to strengthen the sputtered interlayer such as Ti by annealing the resultant coatings at various temperatures and introducing nitrogen gas during interlayer deposition were carried out. | Description: | 244 p. | URI: | https://hdl.handle.net/10356/35954 | DOI: | 10.32657/10356/35954 | Schools: | School of Materials Science & Engineering | Fulltext Permission: | open | Fulltext Availability: | With Fulltext |
