TI-AL-TA-BASED COATING EXHIBITING ENHANCED THERMAL STABILITY

摘要

The present invention relates to a wear resistant coating system comprising a tantalum containing multilayered film consisting of n A layers and m B layers, where n and m are integral numbers larger than 1, deposited alternating one on each other, said multilayered film exhibiting crystalline cubic structure, characterized in that the B layers comprises tantalum and the A layers exhibit a higher defect density than the B layers.
