    摘要： A method of coating an iron-based article includes a first heating step of heating a substrate that includes an iron-based material in the presence of an aluminum source material and halide diffusion activator. The heating is conducted in a substantially non-oxidizing environment, to cause the formation of an aluminum-rich layer in the iron-based material. In a second heating step, the substrate that has the aluminum-rich layer is heated in an oxidizing environment to oxidize the aluminum in the aluminum-rich layer.

    摘要： The invention refers to a process for the formation of a thermal barrier coating on a substrate, comprising the steps of: a) applying a bond coat on the substrate; b) subjecting the bond coat to a low activity aluminizing process, thus obtaining, above the bond coat, a temporary intermediate diffusion layer; c) applying, on the temporary intermediate diffusion layer, aluminum powder in suspension with a solvent or aqueous base, said aluminum powder having size distribution from 15 to 150 μm; d) performing a thermal treatment in a vacuum at a pressure from 10−3 to 10−5 bars, at a temperature from 800° C. to 1050° C. and with an active phase having duration in the range of 60 minutes to 4 hours, thus obtaining above the bond coat an enriched intermediate diffusion layer; and e) applying a definitive barrier layer on said enriched intermediate diffusion layer.

    摘要： In a method for production of a corrosion resistant and/or oxidation resistant coating, at least one metal of the platinum group or an alloy thereof is galvanically deposited onto a surface of a substrate, and thereafter the thusly galvanically coated substrate is aluminized. In a first stage of the galvanic deposition process a current magnitude applied for the galvanizing is increased continuously or step-wise beginning from an initial value up to a maximum value, and in a second stage of the galvanic deposition process the current magnitude applied for the galvanizing is maintained constant at the maximum value. The galvanic deposition of the or each metal of the platinum group or the corresponding alloy may be carried out using an open-celled or open-mesh or porous anode.

    摘要： A composite resistive to high-temperature corrosion and abnormal oxidization, maintains original excellent high-temperature characteristics of Ni alloys over a long period of time, and suitable for applications in a high-temperature such as gas turbines, jet engines, and elements for exhaust-gas systems. A heat-resistant Ni-alloy composite has excellent high-temperature oxidation resistance, including a Ni-alloy substrate that has been subjected to an Al-diffusing treatment. The surface coat has a multi-layer structure including an inner layer composed of an α-Cr phase and an outer layer composed of a β phase (Ni—Al—Cr) and a γ′ phase (Ni3Al(Cr)) on the substrate surface. The Al content in the outer layer is at least 20 atomic percent. The α-Cr phase functions as a diffusion-barrier layer. The outer layer retains and secures a high Al content required for self-regeneration of a defective portion of the Al2O3 layer damaged in an operating condition.
