Airfoil with improved coating system and methods of forming the same
A coating system for a surface of a superalloy component is provided. The coating system includes a MCrAlY coating on the surface of the superalloy component, where M is Ni, Fe, Co, or a combination thereof. The MCrAlY coating generally has a higher chromium content than the superalloy component. The MCrAlY coating also includes a platinum-group metal aluminide diffusion layer. The MCrAlY coating includes Re, Ta, or a mixture thereof. Methods are also provided for forming a coating system on a surface of a superalloy component.
Diffusion barrier to prevent super alloy depletion into nickel-CBN blade tip coating
A diffusion barrier coating on a nickel-based alloy substrate comprising the diffusion barrier being coupled to the substrate between the substrate and a composite material opposite the substrate, wherein the diffusion barrier comprises a nickel phosphorus alloy material.
GALVANIZED STEEL SHEET HAVING EXCELLENT PLATING ADHESION AND CORROSION RESISTANCE, AND MANUFACTURING METHOD THEREFOR
Provided is a galvanized steel sheet having excellent plating adhesion, having a plated layer with improved friction characteristics by means of a predetermined level of Fe elution, and having excellent corrosion resistance; and a manufacturing method therefor.
METHOD OF MANUFACTURING HOT PRESS-FORMED MEMBER HAVING EXCELLENT PRODUCTIVITY, WELDABILITY AND FORMABILITY
An method of manufacturing a hot press-formed member comprises heating a blank of an aluminum-based plated steel sheet in a heating furnace, removing the heated blank from the heating furnace and conveying the removed blank between an upper mold portion and a lower mold portion of a mold, mounted on a press, to be seated; and performing a forming process after the upper mold portion of the mold is in contact with the seated blank.
Multicolor Fixture Finishes
A plumbing fixture having a multi-color appearance includes a first portion including a first finish having a first appearance and a second portion including a second portion having a second appearance that differs from the first appearance. The plumbing fixture further includes a transition region between the first portion and the second portion, wherein the appearance of the third region is graduated from the first appearance to the second appearance between a first end of the transition region adjacent the first portion and a second end of the transition region adjacent the second portion. The plumbing fixture has an ombré appearance as a result of the graduated transition between the first portion and the second portion.
COATED STEEL MEMBER, COATED STEEL SHEET, AND METHODS FOR PRODUCING SAME
This coated steel member includes: a steel sheet substrate having a predetermined chemical composition; and a coating formed on a surface of the steel sheet substrate and containing Al and Fe, in which the coating has a low Al content region having an Al content of 3 mass % or more and less than 30 mass % and a high Al content region formed on a side closer to a surface than the low Al content region and having an Al content of 30 mass % or more, a maximum C content of the high Al content region is 25% or less of a C content of the steel sheet substrate, a maximum C content of the low Al content region is 40% or less of the C content of the steel sheet substrate, and a maximum C content in a range from an interface between the steel sheet substrate and the coating to a depth of 10 μm on a side of the steel sheet substrate is 80% or less of the C content of the steel sheet substrate.
PULSED DIRECTED ENERGY DEPOSITION BASED FABRICATION OF HYBRID TITANIUM/ALUMINUM MATERIAL FOR ENHANCED CORROSION RESISTANCE AND STRENGTH
A method of providing a protective titanium layer to an outer surface of an aluminum component includes providing an aluminum component and forming a first layer of titanium-based bulk metallic glass on the component, wherein formation of the bulk metallic glass layer comprises depositing a titanium alloy powder using pulsed directed energy deposition.
PVD bond coat
A superalloy workpiece includes a superalloy substrate and an interface layer (IF-1) of essentially the same superalloy composition directly on a surface of the superalloy substrate. A transition layer (TL) of essentially the same superalloy and superalloy oxides or a different metal composition and different metal oxides is on the interface layer (IF-1). The oxygen content of the transition layer increases from the interface layer (IF-1) towards a barrier layer (IF-2) of super alloy oxides or of different metal oxides.
Nano-twinned copper layer with doped metal element, substrate comprising the same and method for preparing the same
A nano-twinned copper layer with a doped metal element is disclosed, wherein the nano-twinned copper is doped with at least one metal element selected from the group consisting of Ag, Ni, Al, Au, Pt, Mg, Ti, Zn, Pd, Mn and Cd in a region from a surface of the nano-twinned copper layer to a depth being 0.3 μm, and a content of the metal element in the region is ranged from 0.5 at % to 20 at %. In addition, at least 50% in volume of the nano-twinned copper layer includes plural twinned grains. Furthermore, a substrate including the aforesaid nano-twinned copper layer and a method for preparing the aforesaid nano-twinned copper layer are also disclosed.
INTEGRATED HIGH THROUGHPUT COLD SPRAY COATING MANUFACTURING SYSTEM
In some embodiments, a coating applied to steel reinforcement bar (e.g., steel rebar) that could considerably extend the lifetime of concrete structures by reducing steel rebar corrosion is disclosed. The coating includes a thin, passivating steel (e.g., stainless steel) layer that is applied to the outside of conventional steel rebar. The coating can be applied in-line through metal cold spray manufacturing, which is a high throughput coating technique that can be integrated into existing steel manufacturing plants. Furthermore, a novel, high performance ferritic steel with tailored resistance to corrosion from chlorides is described. The new ferritic steel is distinct from other commercial and experimental steels, and is better suited for coating low-cost steel structures like rebar. Multiple alloying elements including Cr, Al, and Si will each form protective oxides independently, increasing the total amount of protection and extending it over much wider ranges of pH and electrical potential.
