Y-rich oxide distribution in plasma sprayed MCrAlY-coatings studied by SEM with a cathodoluminescence detector and Raman spectroscopy.

Relevancy:  

Y203 thermal sprayed film coated member and process for producing the same.

Relevancy:  

A member is obtained by forming a Y2O3 black spray coating on a surface of a substrate or covering the surface of the substrate with a Y2O3 black spray coating through an undercoat or a middle layer. This coating has good heat characteristics and is good in the resistance to damaging through a high hardness. The Y2O3 black spray coating is produced by subjecting white Y2O3 powdery material to a plasma spraying in an inert gas atmosphere containing substantially no oxygen or by forming a Y2O3 white spray coating and then irradiating an electron beam or a laser beam to this coating to melt at least a part of the white coating under heating to thereby smoothen denseness and blacken the surface of the coating.

Y2O3 thermal sprayed film coated member and process for producing the same.

Relevancy:  

Member comprising a Y2O3 black thermal sprayed film formed on a surface of a base material, and a member comprising a Y2O3 black thermal sprayed film coated on a surface of a base material through an undercoat or an intermediate layer. This film has good thermal properties and good damage resistance by virtue of increased hardness. The Y2O3 black thermal sprayed film is formed by subjecting a white Y2O3 powder material to plasma spraying in a substantially oxygen-free inert gas atmosphere, or by forming a white thermal sprayed film of Y2O3, then exposing this film to an electron beam or a laser beam to heat melt at least a part of the white film, thereby smoothing the film surface and, at the same time, blackening the film.

Y2O3-sealed Nickel-Aluminium protective coatings for Inconel 625

Relevancy:  

SURF Surfaces of flame-sprayed Ni-Al coatings deposited on to Inconel 625 substrates were sealed by Y2O3 film (0.5-1.5µm) derived pyrolytically from Y acetate tetrahydrate-based precursor soln. Y2O3-sealed Ni-Al coating specimens were placed into automated cyclic furnace and subjected to heating-cooling cycle tests (one cycle = 12 h at 900°C + 12 h at 25°C) to evaluate usefulness of coating system in preventing oxidation of underlying Inconel. After 75 cycles, the wt gains of sealed Ni-Al coatings were c. 50% lower than those of unsealed coatings. Such effectiveness of Y2O3 sealer in improving efficacy of Ni-Al protective coatings was due mainly to reactivity with alumina formed by oxidation of Al within coatings. Selective reaction led to formation of crystalline YAlO3 phase. Extended oxidation resulted in transformation of YalO3 into the Y3Al5O12 phase as a result of a secondary reaction between YAlO3 and alumina. Consequently, sealing layers consisting of Y2O3, YAlO3, and Y3Al5O12 contributed to filling and eliminating inherent open spaces in Ni-Al coatings, thereby suppressing diffusion of oxygen through pores. Such oxygen-impervious layers endow Ni-Al layers with long useful life-span as oxidation-resistant coatings for Inconel.

Relevancy:  

Discusses statistical means for meaningfully representing coating thickness & its degree of uniformity. Graph uses silver-coated ballbearing as model. Concepts set out incl. capability index, normal distribution & standard deviation. Graphs show how such concepts are integrated & used in a production setting, where upper and lower coating thickness limits are set. 2 refs

Yarns and fabrics having a wash-durable non-electrically conductive topically applied metal-based finish.

Relevancy:  

Durable non-electrically conductive metal treatments (such as coatings or finishes) for yarns and textile fabrics are provided. Such treatments preferably comprise silver and/or silver ions; however, other metals, such as zinc, iron, copper, nickel, cobalt, aluminum, gold, manganese, magnesium, and the like, may also be present or alternatively utilized. Such a treatment provides, as one example, an antimicrobial fiber and/or textile fabric which remains on the surface and does not permit electrical conductivity over the surface. The treatment is extremely durable on such substrates; after a substantial number of standard launderings and dryings, the treatment does not wear away in any appreciable amount and thus the substrate retains its antimicrobial activity (or other property).
