An alloy comprising Refractory Chromium metal capable of forming an oxide Layer on the surface of Chromium resistant to oxidation and / or corrosionProcedure for Preparation and article made from Said Alloy

摘要

A corrosion-resistant Alloy and / or oxidation includes Chromium, Preparation method thereof and article made with the Alloy, where laaleacion includes Chromium,In the form of Chromium oxide, resistant to oxidation and corrosion, ESP Board produced by glass at high temperature, the Alloy containing dispersed in its Matrix, Chromium oxide Cr2O3,Or a precursor of this oxide.This Alloy can be prepared by a process that comprendeuna metalurgiautilizando Powder consolidation Stage Hot Metal Powders, in particular through Sintering.The application can be done on items that can be used in a corrosive environment or oxidation at high temperature.The Matrix includes: desde10 60% Cr; from 10 to 50% of W and mo from 10 to 70%.The Alloy also includes a Sintering Agent such as Palladium or other platinoide in a proportion of 0.1 to 3% by weight.The Matrix can be chosen between possesses thefollowing Elements: 10 to 40% Cr; 10 to 80% or 80%; 10; 0 to 40% (by weight) of FaithWithin the same dispersion containing oxides: Yttrium, LANTHANUM, LANTHANUM, Cerium, zirconium, HAFNIUM, or Thorium.
