Effect of residual stress on adhesion behaviour of TiN coating
TiN coating prepared by physical vapour deposition on additively manufactured Ti-6Al-4V alloy was studied from the perspective of residual stress to improve adhesion strength. The growth mechanism of TiN coatings was analysed and the coating adhesions were evaluated using a scratch tester. The results showed that the crystal nucleus grew under the surface diffusion and grain boundary migration to form a continuous coating. The preferred directions for crystal growth were the (111), (200) and (220) planes. The compressive stress value has a negative correlation with the bonding strength between the coating and the substrate. Specimen with larger tensile stresses had a more regular cross-section and more compact connection, and protected the coating integrity.
期刊介绍：
The Bulletin of Materials Science is a bi-monthly journal being published by the Indian Academy of Sciences in collaboration with the Materials Research Society of India and the Indian National Science Academy. The journal publishes original research articles, review articles and rapid communications in all areas of materials science. The journal also publishes from time to time important Conference Symposia/ Proceedings which are of interest to materials scientists. It has an International Advisory Editorial Board and an Editorial Committee. The Bulletin accords high importance to the quality of articles published and to keep at a minimum the processing time of papers submitted for publication.
