摘要： A method for forming a thermal barrier coating system on an article subjected to a hostile thermal environment, such as the hot gas path components of a gas turbine engine. The coating system is generally comprised of a ceramic layer and an environmentally resistant beta phase nickel aluminum intermetallic (&bgr;-NiAl) bond coat that adheres the ceramic layer to the component surface. A thin aluminum oxide scale forms on the surface of the &bgr;-NiAl during heat treatment. The &bgr;-NiAl may contain alloying elements in addition to nickel and aluminum in order to increase the environmental resistance of the &bgr;-NiAl. The &bgr;-NiAl powder having a size in the range of 20-50 microns is applied using air plasma spray techniques to produce a surface having a roughness of 400 microinches or rougher. The ceramic top coat can be applied using inexpensive thermal spray techniques to greater thicknesses than achievable otherwise because of the rough surface finish of the underlying &bgr;-NiAl bond coat.

摘要： A bond coat and method of forming a bond coat for a thermal barrier coating system are set forth. The bond coat is a roughened bond coat and comprises a layer possessing an uneven, undulated, and irregular surface. The layer is formed of a metal powder mixture disposed on a substrate, such as a turbine component, by high velocity oxygen fuel spraying. The metal powder mixture comprises at least one of a first powder having a first melting point and a second powder having a second melting point that is higher than the first melting point. The bond coat's uneven, undulated, and irregular surface enhances prevention of de-bonding of elements in a thermal barrier coating system.

摘要： A durable coating process which provides improved adhesive bond strength between the coating and its substrate. This process utilizes spray parameters which generate a unique plasma coating that can be applied through a liquid environment between the spray gun nozzle and the substrate to provide combined ion cleaning, etching and activation of the surface to be coated. The improved surface conditioning allows the creation of an exceptionally strong metallurgical bond at the interface between the splattered droplets of the coating material and the substrate. The improved plasma coating process utilizes a relatively short nozzle-to-work surface distance and is therefore suitable for use directly in a liquid such as water in order to keep the substrate from overheating, which may be more likely to occur if the coating were applied in a gas or vacuum environment. The resulting plasma coating is characterized by high values of adhesive bond strength which are attributable to the high-strength metallurgical bond formed between the coating and substrate.
摘要翻译：一种耐用的涂层工艺，其提供涂层和其基材之间改进的粘合剂粘结强度。该方法利用喷射参数，其产生可以通过喷枪喷嘴和基底之间的液体环境施加的独特的等离子体涂层，以提供组合的离子清洗，蚀刻和活化待涂覆的表面。改进的表面调节允许在涂层材料和基底的溅射液滴之间的界面处产生非常强的冶金结合。改进的等离子体涂覆工艺利用相对较短的喷嘴与工件的表面距离，因此适合直接用于诸如水的液体中，以便保持基材不发生过热，如果涂覆涂层可能会更容易发生在气体或真空环境中。所得到的等离子涂层的特征在于粘合剂粘合强度高，这归因于涂层和基底之间形成的高强度冶金结合。
