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 method for producing a tool coated with a hard coating, the method including the following steps: applying a TiAIN coating layer onto a substrate with a first magnetron sputtering process and applying a TiSiN coating layer onto the TiAIN layer with a second magnetron sputtering process, where x is smaller than or equal to 0.85 and preferably between and including 0.80 and 0.70 whereas the second magnetron sputtering process is performed with power densities greater than 100 W/cmand as such is a HIPIMS process.

Method for producing a double-layer coated cutting tool with improved wear resistance

A coating consists essentially of one or more selected from the group of nitrides of one or more first metals of titanium, zirconium and hafnium beyond 0 at % but less than 100 at % and a balance of silicon, and nitrides of one or more second metals of vanadium, niobium and tantalum.

Compressor vane or blade for engine

When a compressor vane or blade for an engine is used in an environment containing abundant foreign substances, deposits originated from the foreign substances are likely to deposit on surfaces of the vane or blade. The compressor vane or blade according to the present disclosure has a base body of the compressor vane or blade; and a coating covering the base body, which consists essentially of one or more selected from the group of molybdenum disulfide and tungsten disulfide.

Compressor vane or blade for engine with exfoliating coating

A heat-resistant, austenitic cast steel having excellent machinability comprising by mass 0.4-0.55% of C, 1-2% of Si, 0.5-1.5% of Mn, 18-27% of Cr, 8-22% of Ni, 1.5-2.5% of Nb, 0.01-0.3% of N, 0.1-0.2% of S, and 0.02-0.15% of Al, the balance being Fe and inevitable impurities, a machinability index I represented by the following formula: I=100&#xd7;S+75&#xd7;Al+0.75&#xd7;Mn&#x2212;10&#xd7;C&#x2212;2&#xd7;Nb&#x2212;0.25&#xd7;Cr&#x2212;0.15&#xd7;Ni&#x2212;1.2&#xd7;N, wherein each element symbol represents % by mass of each element in the cast steel, meeting the condition of &#x2212;3.0&#x2266;I&#x2266;+14.0, and an exhaust member made thereof.
