A coated tool of the present invention includes a base material; and a hard coating film on the base material. The hard coating film is a nitride or carbonitride which contains aluminum (Al) of 65 atomic % or more and 90 atomic % or less and titanium (Ti) of 10 atomic % or more and 35 atomic % or less with respect to a total amount of metal (including metalloid) elements, and have a face-centered cubic structure. In the X-ray intensity distribution of the α axis of the positive pole figure with respect to the (111) plane of the face-centered cubic structure, the hard coating film have a maximum intensity Ia in the α angle range of 80° to 90° and an intensity in the α angle range of 0° to 70° is 30% or less of the Ia.

Coated tool

The present invention discloses a coated cutting tool having a hard coating film on a surface of the tool. The hard coating film is a nitride, the content ratio of titanium (Ti) with respect to a total amount of metal elements (including semimetal elements) is in a range of 70 at % to 95 at %, the content ratio of silicon (Si) with respect to the total amount of metal elements (including semimetal elements) is in a range of 5 at % to 30 at %, and the content ratio of argon (Ar) with respect to the total amount of metal elements (including semimetal elements) and non-metal elements is 0.1 at % or less. The hard coating film has a NaCl type crystal structure and has an average crystal grain size in a range of 5 nm to 30 nm.

Coated cutting tool

A multilayer hard film-coated cutting tool including a cutting tool body and a multilayer hard film formed on a surface of the cutting tool body, wherein the multilayer hard film comprises at least an upper layer and a lower layer; the upper layer is made of a Ti and Si compound layer; the lower layer is made of a multi-layered film of an A-layer and a B-layer, a layer thickness of the B-layer is equal to or thicker than a layer thickness of the A-layer, a ratio of the layer thicknesses of the A-layer and the B-layer being A-layer:B-layer=1:1 to 1:2, the multilayer hard films having 2 to 8 pairs of the A-layer and the B-layer in a case where a single pair is defined by a combination of a single A-layer and a single B-layer.

Multilayer hard film-coated cutting tool

A workpiece has a body () and a wear-resistant hard coating system (HL), which system comprises a layer of the following composition:(AlCrBZ)X where For a, b and c specific ranges of values are valid.

Workpiece with hard coating

A coating is stripped off a work piece by applying a chromous and aluminiforous coat directly on the work piece and stripping the work piece with an alkaline solution containing a strong oxidant. A single-compartment system can be used, which includes a spray chamber including a circulatory spray-cycle system; a support for holding the work piece; and a media container connected to the spray chamber via a media circulation system.
