摘要： A method for preparing a protective layer (38) on a surface of the substrate (36) that requires a bonding temperature (BT) above a detrimental phase transformation temperature range (28) of the substrate, and then cooling the layer and substrate without cracking the layer or detrimentally transforming the substrate. The protective layer (38) and the substrate (36) are cooled from the bonding temperature (BT) to a temperature (46) above the detrimental phase transformation range (28) at a first cooling rate (30) slow enough to avoid cracking the protective layer. Next, the protective layer and the substrate are cooled to a temperature below the detrimental phase transformation range of the substrate at a second cooling rate (27) fast enough to pass the detrimental phase transformation range before a substantial transformation of the substrate into the detrimental phase can occur.

摘要： A wear alloy coating (14) applied to a substrate material (12) by a cold spray process. Particles of the wear alloy coating material (16) are directed toward a target surface (18) of the substrate at a velocity sufficiently high for the particles to deform and to adhere to the target surface. The size and composition of the particles may be varied during the cold spray process to produce a coating with a varying property across the depth of the coating. Particles of the wear alloy material may be applied by cold spraying along with particles of a second material such as a lubricant or a ceramic material. For Group 5 hard facing materials, the size and distribution of the embedded carbide nodules may be controlled by controlling the selection of the carbide particles being sprayed. The cold spray process permits a wear alloy coating to be applied proximate a brazed joint or over a directionally stabilized or single crystal material without degrading the underlying material.

摘要： A method that simultaneously monitors and captures vibration acceleration signals at locations comprising at least one site sourcing environmental excitations and a target site, which target site is selected from a planned machinery foundation site or one or more sites interfacing between elements of machinery to be placed on such foundation; extracting amplitude and frequency data from the frequency representations of the domains of such signals; quantifying displacement excitations from such data at such locations; and providing transmissivity ratios along the vibration path by summing the displacement excitations at different frequencies at each of the locations and then ratioing the sum at either the planned machinery foundation site or at a selected joint site with the sum at the environmental excitation site, thereby indicating the relative vibration stiffness between such sites. Such transmissivity ratios can then be used to modify the design of the proposed foundation, and/or the design of interfacing elements of the machine.

摘要： A process (30) for the repair of a component part (36,66) incorporating a cold spray process step (50) for depositing material particles (54) to fill a discontinuity (40) in the part surface (42) or to create a desired surface geometry (78) on the part (66). The cold spray process may be controlled to provide a grit blasting effect prior to depositing the material in order to remove contaminants (48) from the surface of the part. The material deposited (56) by the cold spray process may form a joint (78) between an insert (72) and the part (66). The process may be used to repair parts made of directionally solidified (DS) or single crystal (SC) base material (44) without causing a re-crystallization of the base material. The process may further be used to deposit repair material (56) over a braze material (22).

摘要： A fusion weldable superalloy containing 0.005-0.5 wt. % scandium. In one embodiment, the superalloy may have a composition similar to IN-939 alloy, but having added scandium and having only 0.005-0.040 wt. % zirconium. A gas turbine component may be formed by an investment casting of such a scandium-containing superalloy, and may include a fusion weld repaired area. A scandium-containing nickel-based superalloy coated with an MCrAlY bond coat will have improved cyclic oxidation resistance due to the sulfur-gettering effect of the scandium.

摘要： A system and method to create frequency derived, pre-characterization templates to be used by a machine operator for determining when a tool breaks in one spindle of a multi-spindle machine tool. The pre-characterization template is created by first impacting the tool or the holder and recording the time domain of the frequency pattern of vibrations. The natural frequencies of the tool/tool holder/spindle vibrations which include the vibration frequencies of the tool braking are recorded. Pre-characterization templates are created using FFT techniques to identify only those frequencies indicative of tool breakage. The machine tool operator then uses the monitoring system with pre-characterization templates during machine tool operation and is notified in real time of the breakage of a tool in a single spindle or a multi-spindle machine.
