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 formingdie is filled with a powder () of electrode material, the powder () of electrode material filled in the forming die is compressed to form a porous powder compact (), the porous powder compact () is set in place in a chamber () of a heat-treating furnace (), the chamber () is supplied with inert gas or hydrogen gas, and inert gas or hydrogen gas is heated by heaters () in the heat-treating furnace () and blown toward the powder compact (), as blows circulating in the chamber (), whereby the powder compact is heated with heat of convection flows of inert gas or hydrogen gas, or mixed gas containing inert gas as principal component and hydrogen gas, so the electrode material of the powder compact is sintered.

Fabrication method of electrode for spark surface modification, and spark surface modification electrode

A method for forming a dense coating on a limited region of a subject body is disclosed. The method is composed of the steps of: applying one selected from the group of a compressed body of a powder of a metal and a sintered compressed body of a powder of a metal to a working electrode; executing discharge deposition to deposit a first coating from the working electrode on the subject body by applying the subject body as a workpiece of the discharge deposition; executing discharge deposition to deposit a second coating from the working electrode on the first coating by applying the subject body as a workpiece of the discharge deposition; and heating the subject body in one selected from the group of a vacuum, an air and an oxidizing atmosphere so as to densify the second coating or oxidizing the second coating at least in part to generate a solid lubricant substance.

Surface treatment method and repair method

A protective coating for protecting a component of a gas turbine engine or such from wear is provided with a base coating consisting essentially of metal and including a pore, and a spherical particle filling the pore, at least a surface of which consists essentially of a ceramic.
