Abstract
Amorphous Al–Mg–B thin films were synthesized via a combinatorial sputtering approach The properties of Al–Mg–B films with the varying deposition temperature was investigated The deposition temperature was found to dominate the hardness of the amorphous asdeposited film The hardness increases with increasing deposition temperature and may even exceed that of crystalline AlMgB14 material The high hardness may be attributed to the existence of randomly distributed B12 icosahedra structure Therefore the thin film that was deposited on cemented carbide shows wellcutting performances in turning Ti alloy bar At the same time an appropriate method of pretreatment is the key to ensure the coating tool with the excellent adhesion by impact fracture testThis study was financially supported by the Fundamental Research Funds for the Central Universities No DUT10JN08 the Natural Science Foundation of Jiangsu Province No BK2011252 and the Industry Science and Technology Supported Plan of Changzhou No CE20110012
