摘要:
A coated cutting insert for removing material from a workpiece that includes a substrate is disclosed. A wear-resistant coating on the substrate that includes an α-alumina layer and a Zr— or Hf— carbonitride outer layer deposited on the α-alumina layer. The Zr— or Hf— carbonitride outer layer is subjected to a post-coat wet blasting treatment. The wet blasting changes the stress condition of the exposed alumina coating layer from an initial tensile stress condition to a compressive stress condition.
摘要:
A coated article such as a coated cutting tool or coated wear part, which includes a substrate and a coating scheme on the substrate. The coating scheme has a titanium-containing coating layer, and an aluminum oxynitride coating layer on the titanium-containing coating layer. The aluminum oxynitride includes a mixture of phases having a hexagonal aluminum nitride type structure (space group: P63mc), a cubic aluminum nitride type structure (space group: Fm-3m), and optionally amorphous structure. The aluminum oxynitride coating layer has a composition of aluminum in an amount between about 20 atomic percent and about 50 atomic percent, nitrogen in an amount between about 40 atomic percent and about 70 atomic percent, and oxygen in an amount between about 1 atomic percent and about 20 atomic percent. The method of making the coated article includes a step of providing a substrate and depositing an aluminum oxynitride coating layer from a gaseous mixture that includes nitrogen, aluminum tri-chloride, ammonia, carbon dioxide, hydrogen chloride, optionally carbon monoxide, optionally argon, and hydrogen.

摘要:
The invention relates to a method of coating a cemented carbide or cermet substrate body by means of PVD, in which the fully sintered substrate body is subjected without further intermediate treatment before PVD coating to a blasting treatment using a particulate blasting agent until the zone close to the surface of the substrate body has a residual stress which is at least essentially of the same magnitude as the residual stress present in the single or first applied PVD layer. The invention further relates to such a coated cemented carbide or cermet body, in particular in the form of a cutting tool.

The invention relates to a tool, especially a cutting tool, comprising a substrate member onto which at least one layer is deposited by means of CVD, and a method for the chemical vapor deposition of a two-phase layer on a sintered part. According to the invention, the single deposited layer or at least one of the layers is provided with a TiCN phase, TiOCN phase, TiOC phase, or TiC phase and an additional phase consisting of ZrO2 and/or HfO2. CH3CN, C5H5N, or C6H6 is used in the gas atmosphere for producing such a layer in addition to TiCl4, HfCl4, and/or ZrCl4 and CO2, the remainder being composed of H2 and/or Ar.
