    摘要： A coated article and method for producing the coated article are described. The article is coated with a system which provides protection against oxidation and corrosion and which significantly reduces the substrate temperature. An MCrAlY layer is applied to the article to be protected and a columnar grain ceramic is applied by vapor deposition to the MCrAlY coated article. An alumina layer which exists between the MCrAlY layer and the columnar ceramic layer provides for the adherence of the columnar layer to the MCrAlY layer. An important feature of the invention is that the interface between the MCrAlY layer and the alumina layer has a low surface roughness and this greatly improves the columnar ceramic layer adherence.

    摘要： A coated article and method for producing the coated article are described. The article is provided with a coating system which provides protection against hot corrosion at moderate temperatures (1200.degree.-1700.degree. F.). An overlay coating based on a metal selected from the group consisting of iron, nickel or cobalt or mixtures thereof and containing chromium and optionally aluminum, yttrium and/or hafnium is applied to the article to be protected. A silicon rich surface zone is produced at the surface of the overlay coating. Methods including pack cementation and physical vapor deposition are described for producing the coating.

    摘要： Concepts relating to the heat treatment of single crystal superalloy articles are disclosed. A first concept is the use of a heat treatment sequence which includes incipient melting of the article being heat treated followed by one or more steps which essentially heal the incipient melting damage. A second concept relates to the treatment of previously heat treated single crystal articles which have incipient melting. Methods are disclosed for healing this damage and for recovering the mechanical properties of such articles. A third concept disclosed is a particular cycle which permits effective heat treatment of a specific single crystal alloy composition.
