A cylinder for a molding machine comprising a HIP-sintered lining layer on an inner surface of a cylindrical steel body, the lining layer comprising 38-70% by volume of tungsten carbide particles having a median diameter d.sub.50 of 1-7 m and a matrix composed of an Ni-based alloy, and the maximum length of the matrix in an arbitrary cross section being 12 m or less.

A MAX-phase material is provided for a cutting tool and other applications.

A composition based on a certain chromium-free silicate-based binder is described. The composition is an aqueous solution of lithium-doped potassium silicate in combination with an aluminum or aluminum alloy powder, zinc powder or a combination thereof. The coatings of the present invention are capable of achieving a full cure at temperatures as low as 350-450 degrees F. by the inclusion of a colloidal solution of a nano-sized ceria, thus making the coatings especially suitable for application on temperature sensitive base materials.

A method for manufacturing an aluminum circuit board including a step of spraying a heated metal powder containing aluminum particles and/or aluminum alloy particles to a ceramic base material, and of forming a metal layer on a surface of the ceramic base material. A temperature of at least a part of the metal powder is higher than or equal to a softening temperature of the metal powder and lower than or equal to a melting point of the metal powder at a time point of reaching the surface of the ceramic base material. A velocity of at least a part of the metal powder is greater than or equal to 450 m/s and less than or equal to 1000 m/s at the time point of reaching the surface of the ceramic base material.

The present invention regards a metallic component of a distillation and/or fermentation apparatus, characterized by being covered with at least one layer of nanostructured copper, said layer of nanostructured copper possibly comprising also nano-particles of TiO2. Furthermore, the present invention regards methods for covering said metallic component with at least one layer of nanostructured copper which may also comprise nanoparticles of TiO2. Finally, the present invention regards the use of said components in distillation and/or fermentation processes, in particular for the alcoholic distillation of spirit beverages.

A forming method of an yttrium oxide fluoride (YOF) coating film and a (YOF) coating film formed thereby are disclosed. The YOF coating film has no or extremely small pores therein and a nanostructure to increase light transmittance thereof, and has high hardness and high bonding strength and thus can protect a transparent window of a display device. The method for forming an YOF coating film involves the steps of: providing pretreated YOF powder having a particle diameter ranging from 0.1 to 12 m; receiving a transfer gas supplied from a transfer gas supply unit and receiving the pretreated YOF powder supplied from a powder supply unit to transfer the pretreated YOF powder in an aerosol state; and colliding/smashing (spraying) the pretreated YOF powder transferred in the aerosol state with/onto a substrate in a process chamber to form an YOF coating film on the substrate.

A spray nozzle can control a film region easily. A spray nozzle of an embodiment includes, a nozzle main body, a nozzle tip section connected to a tip of the nozzle main body, and at least one path changing section which is provided in a passage of the carrier gas in the nozzle tip section and changes a path of the film material.

A method of treating a superalloy article, including selecting an article having a superalloy composition, whereby the article has a treatable feature on its surface. The method further includes removing a base alloy from a region abutting a first portion of the treatable feature. The method further includes treating a second portion of the treatable feature with a treatment composition to remove surface oxides. The method further includes inserting a treatment material into the first portion of the treatable feature followed by depositing the base alloy in the first portion of the treatable feature. The method further includes heat treating the article at a temperature above the melting point of the treatment material whereby the treatment material flows into the second portion of the treatable feature forming a treated article.

A pipe structure includes a pipe disposed in a state of contact with the air, a fluid with a temperature of at least 100 C. flowing inside the pipe; and a coating material containing nickel oxide and coated onto an outer periphery portion of the pipe
