Ti—Al—Ta-based coating exhibiting enhanced thermal stability

摘要

A wear resistant coating system including a tantalum-containing multilayered film having n A layers and m B layers, where n and m are integral numbers larger than I, deposited alternating one on each other. The multilayered film exhibits crystalline cubic structure, and is characterized in that the B layers include tantalum and the A layers exhibit a higher defect density than the B layers.
