  • the Al-13Co-26Ce powder was prepared by gas atomization.

  • Particle velocities were measured using the DPV-CPS (Tecnar Automation Ltd., St- Bruno, Quebec, Canada), a laser in-flight diagnostic system. While a continuous laser illuminates a measurement volume, a dual-slit photomask captures the signal generated by individual particles passing in front of the sensor. The signal from the photosensor is then amplified, filtered, and analyzed. The in-flight diagnostic of each individual particle that crosses the measurement volume is performed by determining the time between two peaks of the particle signal. The particle velocities are then obtained by dividing the distance between the two-slits by the particle's flight time [21]. In this study, the velocity measurements were taken at a location 5 mm from the spray gun exit. In order to avoid particle build-ups and rebounds that could obstruct the sensor field of view, the particle velocity measurements were performed without the presence of a substrate at the exit of the spray gun.

  • the test specimens were supported in the same manner as a cantilevered beam at one end and were subjected to an alternating force at the other, as depicted in Fig. 3.

Secondary electron and backscattered electron images of the coatings' cross-sections were used to evaluate the microstructural features. Porosity and oxide contents were measured by optical microscopy and analyzed using a commercial metallographic software. A grey scale delineation technique was used to quantify the area fraction of oxides, porosity, and aluminum. X-ray diffraction (XRD) were carried out using a Scintag XDS-2000 diffractometer using Cu Ka radiation at 50 steps per degree and a count time of 5 sec per step.
  • XRD X-ray diffraction
  • Bond strength evaluations were conducted using the ASTM Standard C 633-01 [19]. Coatings were produced on grit-blasted standard test samples having a 25.4 mm diameter and an overall length of 38.1 mm. Several passes were carried out to cover the entire surface of the sample. The top portion of the coating was machined flat and glued to an uncoated test sample, using an adhesive (Master Bond EP- 15, Ralphensack, NJ, USA). The assembled parts were cured at 17O 0 C for 90 minutes in a V block device that ensures proper alignment. Before testing the coatings, the bonding agent was tested separately on uncoated test samples, and failed at 82 MPa, which conforms to the product specifications.
  • Example 5 Particle velocity measurements Prior to producing the Al-Co-Ce coatings, particle velocity measurements were performed under the test conditions listed above. The measured particle velocity distribution is shown in Fig. 5. The particle velocities varied between 600 and 1000 m/s, with an average of 842 ⁇ 80 m/s. This high average particle velocity was due to the small average particle size. A narrow particle velocity distribution was obtained as a result of the slender particle size distribution.
  • Ce coated specimens are presented in Fig. 6. At all three stress levels, the specimens with CGDS deposited Al-Co-Ce outperformed the bare and the Alclad coated specimens. At a stress of 50 ksi, the Alclad and the Al-Co-Ce coated specimens failed at about the same number of cycles. However, as the stress amplitude decreases, the Al-Co-Ce coatings significantly improve the fatigue performance of the substrates. At 30 ksi, the Al-Co-Ce coatings outlasted the bare and the Alclad specimens by over an order of magnitude.
  • the fatigue curve for the coated samples indicates that the Al-Co-Ce coatings give rise to a significant increase in fatigue properties of the coated substrates in comparison with the uncoated substrates at all stress levels.
