Title:
金属基板の表面にチャネルを形成する方法
Document Type and Number:
Japanese Patent JP4731101
Kind Code:
B2
Abstract:
A method for forming a channel (80) within a coated (72, 74), metal-based substrate (54) is described. In one technique, a channel-forming material (50) is first deposited on the substrate (54), followed by the deposition of a bonding agent (58), such as a braze. One or more coatings (72, 74) can then be applied over the substrate (54). In one embodiment, the channel (80) is formed when the channel-forming material (50) is subsequently removed. In another embodiment, the channel (20) is formed due to the lack of adhesion between particular channel-forming materials (10) and the overlying bonding agent (18). Related articles are also described, e.g., gas turbine components which include protective coatings and a pattern of cooling channels.
