MULTILAYERED CVD COATED ARTICLE AND PROCESS FOR PRODUCING SAME |
摘要 |
The invention relates to a cemented carbide or ceramic article having a multilayered coating of a plurality of ultrathin CVD coating layers, and a process for producing same. Each of the ultrathin CVD coating layers has a thickness of approximately 200 nanometers or less. The multilayered coating ranges from approximately 50-400 layers, has excellent adherence and a smoothness and a hardness of at least approximately 40 GPa. The CVD coated article of the present invention exhibits improved coating properties of excellent smoothness, uniformity, toughness, hardness and abrasive wear resistance.
