COATING MATERIALS FOR A CUTTING TOOL OR AN ABRASION RESISTANCE TOOL

摘要

PURPOSE: A coating materials for a cutting tool or an abrasion resistance tool, capable of the dominant growth of another surface or plane of A-AL2O3, is provided to improve the wearability and lubrication by forming the shape of the outermost layer plate. CONSTITUTION: A coating materials for a cutting tool or an abrasion resistance tool comprises a lower layer(10), a bonding layer(20) and an outermost layer(30). The lower layer is laminated at the upper part of the base material in a MT CVD construction method. The bonding layer is formed to be contiguous on the top of the lower layer. The outermost layer is formed to be contiguous on the top of the bonding layer. The outermost layer is laminated using a HT CVD construction method.
