A sliding member of the present invention includes a coating on a base material. The coating contains hard metal particles and corrosion-resistant metal particles that have hardness lower than that of the hard metal particles. The hard metal particles contain particles that have at least Vickers hardness of 600 Hv or higher. The corrosion-resistant metal particles are made of at least one kind of metal selected from the group consisting of copper (Cu), cobalt (Co), chromium (Cr), and nickel (Ni), or are made of an alloy containing said metal. The coating has a cross section in which the hard metal particles are dispersed in an island manner in a particle aggregate of the corrosion-resistant metal particles and in which an area ratio of the corrosion-resistant metal particles is 30% or larger. Thus, corrosion of the hard metal particles in the coating is prevented, whereby the sliding member maintains wear resistance for a long time.

Methods of forming a desired geometry at a location on a superalloy part are disclosed. The method may include directing particles of a powder mixture including a low melt temperature superalloy powder and a high melt temperature superalloy powder to the location on the superalloy part at a velocity sufficient to cause the superalloy powders to deform and to form a mechanical bond but not a metallurgical bond to the superalloy part. The directing of particles continues until the desired geometry is formed. Heat is applied to the powder mixture on the repair location. The heat causes the low melt temperature superalloy powder to melt, creating the metallurgical bonding at the location. Another method uses the same directing to form a preform for repairing the location on the part. The low melt temperature superalloy powder melts at less than 1287° C., and the high melt temperature superalloy powder melts at greater than 1287° C.

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 μm; 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.

Specifically, the present invention provides a plasma treatment detection indicator comprising a color-changing layer that changes color by plasma treatment, the color-changing layer comprising metal oxide fine particles containing at least one element selected from the group consisting of Mo, W, Sn, V, Ce, Te, and Bi, the metal oxide fine particles having a mean particle size of 50 μm or less.

Hexavalent chromium-free slurries are provided that are capable of achieving a full cure at temperatures as low as 330-450 degrees F., thus making the coatings especially suitable for application on temperature sensitive base materials. The slurries are suitable in the production of protective coating systems formed by novel silicate-based basecoats that are sealed with novel phosphate-based topcoats. The coating systems exhibit acceptable corrosion and heat resistance and are capable of replacing traditional chromate-containing coating systems.
