摘要:
A propeller blade (200) includes a metallic foam core (204) and a structural layer (206) that surrounds at least a portion of the metallic foam core (204).
摘要:
A method (20) of verifying performance of a coated part includes calculating (22) a deflection value as a function of a predetermined strain threshold value and a total thickness of a test coupon that comprises a coating on a substrate. The coating of the test coupon is co-deposited in a deposition process (28) for producing a coated part. The test coupon is bent (24) in an amount equal to the calculated deflection value and then evaluated (26) as an indication of whether a mechanical characteristic of the coated part meets a specified level.
摘要:
A method (12) of processing an article includes mechanically working (20) an article having a metallic layer disposed on a titanium substrate and establishing (22) a residual stress region that extends through the metallic layer and at least partially into the titanium substrate.
摘要:
A method of processing an article having a substrate and a cobalt-phosphorous coating disposed on the substrate includes heat treating (22) the article. At least one physical characteristic of the cobalt-phosphorous coating is altered (24) using the heat treating to thereby change (26) a performance characteristic of the article. For example, the article may be an actuator component having a bore or a shaft that is movably disposed at least partially within the bore.
摘要:
A method of forming a bearing coating (24) includes the steps of depositing a porous layer (26) on a substrate (22) and depositing a lubricating material (28) within pores of the porous layer. The porous layer and the lubricating material form a bearing coating on the substrate. The bearing coating includes between about 1 vol% and about 20 vol% of the lubricating material with the balance being the porous layer.
摘要:
A method of making an assembly is disclosed. According to the method, a curable sealant (12') is applied to a metal surface of a first article (10) , and the curable sealant (12') and first article (10) are stored under conditions to maintain the curable sealant (12') in an at least partially uncured state. The method further includes contacting the curable sealant (12') on the first article (10) metal surface with an electrically conductive surface of a second article (20,22), and curing the curable sealant (12').
