Composition coated metal corrosion resistant coating and method to prevent metal corrosion by metal Spraying metal surfaces exposed to carbon oversaturated Environments comprising Said composition

摘要

The present Invention provides compositions of metal coated high-performance corrosion resistant metal Coating and Methods for providing such compositions.The coated metal compositions are represented by structure (PQR), where p is an oxide Layer on the surface of PQR), Q is a Coating metal Layer interposed between P and R, and R is a base metal. P includes alumina, Chrome oxide, silica, Mullite or mixtures thereof.Q includes ni and al and at least one Element selected from the group consisting of CR, si, MN, fe, co, B, C, N, P, GA, GE, as, in, SN, SB, Pb, SC, la and CE, ti, Zr, HF, V NB, ta, MO, W, RU, RH, ir, PD, AG, au, Cu, and mixtures thereof.R is selected from the group consisting of carbon Steels, Low Chromium Ferritic Stainless Steel, Austenitic Stainless Steel, duplex Stainless Steel, Alloys, Inconel, Incoloy Alloy, fe ni based Alloys, Alloys based on ni and Co based Alloys.The advantages exhibited by the compositions described include coated metal corrosion Resistance improved by Spraying the metal High Temperature Carbon supersaturation in environments with relatively low Oxygen partial pressures. The coated metal compositions are suitable for use in equipment of the Generation Process of synthesis gas.
